IP 240 Preface Preface In addition to open and closed-loop control, the programmable controllers of the SIMATIC S5 family execute special tasks such as positioning and counting. So that these auxiliary functions do not unnecessarily load the central processor (S5 CPU), they are handled by standalone "intelligent" I/O modules. These have their own microprocessors and execute special time-critical tasks autonomously.

IP 240 1 System Overview System Overview Intelligent input/output modules (I/Os) extend the field of applications of the SIMATIC S5 programmable controller system. They are technology-oriented and off-load the central processor by preprocessing the input signals. Digital input modules can resolve pulses up to a frequency of 100 Hz. The IP 240 can be used for applications with higher frequencies and for connecting incremental encoders.
1P 240 System Overview In the position decoding, counting and positioning modes, the 1P 240 can be used as a standalone module in the U-range programmable controllers S5-1 15U, S5-135U (CPU 922 and 928), S5-150U and S5-155U. Operation as an expansion to the 1P 252 closed-loop control module with direct data exchange between the 1/0 modules is only possible in the S5-1 15U programmable controller.

Operation 5.1 IP 240 Settings for Interrupt Generation The processing of interrupt signals makes it possible to respond rapidly to status changes. In the SIMATIC S5 programmable controllers, a distinction is made between two types of interrupts: • ”Servicing IRx interrupt circuits” (S5-115U, S5-135U and S5-155U in the 155U mode) • ”Reading I/O byte 0” (S5-150U and S5-155U in the 150U mode). 5.1.
IP 240 Operation If several IP 240 modules use one interrupt circuit, the current interrupt source must be determined by reading the interrupt request bytes of all modules or by additionally evaluating I/O byte 0. This must be taken into account in the STEP 5 program due to the system characteristics of the S5-115U CPUs ( Section 5.1.2). Note • • • • 5.1.2 In the S5-115U, S5-135U and S5-155U, only one of the coding switches S2.1 to S2.4 may be closed at any given time.
Operation IP 240 Switchbank S1 1 PB 0.0 2 0.1 3 0.2 4 0.3 5 0.4 Switchbank S2 6 0.5 7 0.6 8 7 8 on on off off 0.7 I/O byte 0.0 to 0.7 Master or Slave Enable for I/O byte 0 Fig. 5-3. Allocation of Coding Switches on Switchbanks S1 and S2 to Interrupt Generation with I/O Byte 0 The coding switches on banks S1 and S2 shown in Fig. 5.3 have the following meaning: on: The corresponding bit of I/O byte 0 is set in response to an interrupt signal on the I/O module.
IP 240 Operation Example for setting the coding switches Three IP 240s are to be enabled for interrupt generation. One IP 240 is to be operated as master module and the other two as slave 1 and slave 2. Slave 1 is assigned to PY 0.1 and slave 2 to PY 0.2. Bits PY 0.3 to PY 0.6 are reserved by other modules. PY 0.7 is not used and must be masked on the master module or else OB9 must not be programmed. Fig. 5-4 shows the necessary settings of coding switches on the IP 240 modules.
Operation IP 240 Additional programming in the organization blocks for the S5-115U: a) The interrupt service routine must be programmed in an FB so that it may execute several times. • I/O byte 0 must be read once at the beginning of interrupt processing to determine which IP triggered the interrupt. • I/O byte 0 must also be read at the end of the interrupt service routine. If a new interrupt request is pending, it must be serviced without exiting the interrupt OB.
IP 240 5.3 Operation Matching to Encoder Signals You can connect the following to the IP 240 as position encoders: • symmetrical incremental encoders with 5 V differential signals complying with RS 422A via inputs A/A, B/B, Z/Z and • asymmetrical incremental encoders with 5 V DC or 24 V DC signals via the inputs A*, B* and Z*. You can connect encoders with 5 V DC or 24 V DC signals to the CLK, GT and IN binary inputs. You can set coding switches for matching the IP 240 to the encoder signals. 5.3.

IP 240 Functional Description 6 Functional Description 6.1 Module Functions The IP 240 is an intelligent I/O module for acquiring and preprocessing encoder and counting pulses. The module has two channels and can be initialized for the relevant application via the user program. 6.1.1 Modes The IP 240 can be operated in the positon decoding, counting, positioning and IP 252 expansion modes.
Functional Description 6.1.2 IP 240 Digital Outputs The digital outputs on the module can be used for direct driving of actuators and displays for particular process states (actual values). The digital outputs can be set to a predefined state by the user program. This takes place at a higher level than when the outputs are set as a function of the actual value.
IP 240 Functional Description Wirebreak/short-circuit (red WB LED) When a channel is set to symmetrical pulses, the encoder cable is monitored by evaluating the two pulse trains of an encoder track. Detection of a wirebreak/short-circuit is indicated separately for each channel for the duration of the fault condition with the red WB (WireBreak) LED. Hardware fault (red MF LED) The red MF (Module Fault) LED indicates a hardware fault on the module.
Functional Description IP 240 6.2.1 Configuring Function Blocks Configuring function blocks serve to select the modes. Each mode is assigned its own function block: • FB 167 for positioning mode ( Section 10.23.2) • FB 169 for position decoding mode ( Section 7.3.1) • FB 171 for counting mode ( Section 8.3.1) • FB 173 for IP 252 expansion mode ( Section 9.3.1) Configuring FBs are normally called in Restart organization blocks (OB20, OB21, OB22).
IP 240 Functional Description 6.3 Restart Characteristics 6.3.1 Power On After ”Power on” a test routine is initiated on the IP 240 to verify proper functioning of the module. If the routine executes without error, the module is in a wait state which allows configuring of the channels. Any errors detected are stored in data words 8 to 10 of the specified data block when configuring, and are indicated with the red MF LED. The digital outputs are switched to the inactive state after ”Power on”. 6.3.

IP 240 6.4.2 Functional Description Parameter and Data Errors Parameter errors When parameter errors occur, the function block sets bit 1 in the PAFE byte. Parameter errors occur when • the function block is not compatible with the IP firmware • the function block is incorrectly initialized • the channel was not configured, or it was not configured for this control FB. The function block enters the precise cause of error in data word 13 of the specified data block, and the data block is exited.
Functional Description 6.5 IP 240 Multiprocessor Operation In the S5-135U and S5-115U PLCs with multiprocessor capability,the IP 240 can also be used when these PLCs are equipped with more than one processor. Note that an IP 240 can be addressed by one processor only. The IP 240 must be assigned to the CPU with which it is to interchange data.

IP 240 Position Decoding 7 Position Decoding 7.1 Application In this mode, the IP 240 can be used in all applications in which position changes are to detected and decoded using incremental encoders. The module can process encoder pulse trains with a frequency of up to 500 kHz for symmetrical encoders and 100 kHz for asymmetrical encoders. The function of a cam controller can be simulated by presetting reference tracks. Error detection during signal acquisition is possible by monitoring signals. 7.
Position Decoding IP 240 Changing the counting direction To change the counting direction, you must interchange the encoder signal connections as follows: • for symmetrical encoders, interchange A/A and B/B. • for asymmetrical encoders, interchange A* and B*. Actual value range and overrange The actual value range is defined as - 99,999 to+99,999. - 99,999 Overrange ... - 1 0 - 99,999 ... -1 0 +1 ... +99,999 Defined actual value range 0 +1 ... +99, 999 Overrange Fig. 7-2.
IP 240 Position Decoding The zero offset value thus always offsets the zero point of the actual value range to the reference point. A zero offset can be revoked by transferring a ”0” value to the IP. Configuring FB 169 does not transfer the zero offset entered in the DB. Configuring FB 169 does not transfer the zero offset entered in the DB.

IP 240 Position Decoding Transfer of the initial values from the data block to the IP 240 The limit values are initially transferred to the IP with configuring FB 169. During operation, you can enter modified limit values with control FB 170. • Transfer by calling configuring FB 169 Enter the limit values which are to be transferred to the IP in DR 29. In DR 29, one bit is assigned to each track. ( Table 7.
Position Decoding IP 240 Triggering a process interrupt Every REFn bit can trigger a process interrupt when it goes from 0 to 1 (rising edge). You must indicate which REFn bits are to trigger interrupts by setting the corresponding bits (0 to 7) in the PRA1 parameter for configuring FB 169. Each of these bits is allocated to a separate track. The triggering of interrupts is independent of synchronization of actual-value acquisition.
IP 240 Position Decoding If you set bit DIGn/9 to ”0”, a change in the REF bit from 0 to 1 sets the output only when the actual value enters the track over a track limit. Note If DIGn/9 is set to ”0”, actual value-dependent triggering of process interrupts is disabled until the end of the next module firmware cycle in the following cases: • for all of the channel's tracks following transfer of a zero offset and • for the modified tracks following the transfer of new track limits.

IP 240 Position Decoding Traversing speed and track width In order for entry into a track to be detectable in every module firmware cycle, the traversing speed must be matched to the minimum track width. The encoder pulses acquired by the IP are counted in a counter chip. The current (internal) count is read out once in each module firmware cycle and then postprocessed to produce the (external) actual value. The track limits are compared to this actual value.

It applies to all tracks of a channel and is only transferred to the IP 240 during a configuring pass.
IP 240 Position Decoding If the direction is reversed outside the hysteresis range following switching of an output, the switching point at the track limit is retained ( Fig. 7-7).
Position Decoding IP 240 The output is switched analogously upon entry into and upon exit from the upper track limit. The output is reset when the actual value reaches the ”upper track limit+hysteresis”. (without Fig.) b) Setting of an output Fig. 7-9 shows switching of an output upon exit from and upon entry into the upper track limit. The output is reset when the upper track limit is exceeded, and the specified hysteresis value goes into force for this limit.
IP 240 7.2.5 Position Decoding Forcing the IP Outputs You can use control bits DAnF and DAnS (n=1 for digital output 1 or n=2 for digital output 2) to indicate whether output D1 or D2 • • • is to be enabled for actual value-dependent switching by the IP (if so, set DAnF to 0 and DAnS to 1 in DL17) is to be set without regard to the actual value (if so, set DAnF to 1 and DAnS to 1 in DL17) is to be reset without regard to the actual value (if so, set DAnF to 0 and DAnS to 0 in DL17).
Position Decoding IP 240 In addition, the following are carried out on the basis of the specified configuring data: • any outputs that are set are reset • an interrupt is generated for DRBR or NPUE and interrupt bit DRB or NPU is set in the interrupt request bytes. Status bit DRBR is reset on the IP when the fault has been rectified and • the status area has been read at least once or • the interrupt request bytes were read ( Section 7.2.7) and the fault that triggered the interrupt was a wirebreak.
IP 240 Position Decoding Invoking the interrupt servicing OBs in the S5-150U and S5-155U PLCs (150 mode) In the S5-150U and S5-155U (150 mode), the associated interrupt servicing OB is invoked at the next block boundary when one of the bits in I/O byte 0 changes its values. Use the ABIT parameter in configuring FB 169 to specify whether the OB is to be invoked every time the bit changes its value or only when it goes from 0 to 1.
Position Decoding 7.2.9 IP 240 Reference Point Approach Since incremental encoders cannot indicate the absolute position after a power failure, a reference point must be approached to calibrate a measuring system. The location of the reference point is determined by the zero mark or reference signal (Z signal) emitted by the encoder during a preliminary signal. To generate the preliminary signal, you must connect a bounce-free switching element within the traversing range.
IP 240 Position Decoding Aborting a reference point approach The reference point approach initiated by setting the REFF bit is normaly terminated, following synchronization, with a negative-going edge at the preliminary contact input.

IP 240 Counting 8 Counting 8.1 Applications In this mode, the IP 240 can be universally used for pulse counting. The module can process pulse trains with frequencies of up to 70 kHz. 8.2 Principle of Operation For the counting mode the following STEP 5 modules are necessary: • A data block You must create a data block (DB) prior to calling the configuring function block for the first time. New data must be entered in this DB prior to its transfer to the IP 240 by the FB 172.
Counting IP 240 When the defined actual value range is exceeded, the counter enters overrange and the IP sets status bit UEBL (overflow). When set, the UEBL bit can trigger an interrupt. You must indicate whether or not it is to do so via the PRA parameter during configuring ( Section 8.3.1). The UEBL bit is reset when the status area or interrupt request bytes are read. When the counter has entered the overrange, the pulses are only counted.
IP 240 8.2.2 Counting Final Value Storing the final count When you evaluate the actual value, you are evaluating the current count. The IP also makes the actual value of the preceding count available, i.e. the count value at the instant of the first negative GATE signal. This is referred to as the final count. This value is retained until the next negative GATE signal, and can be read out from the IP. When the final value is stored at termination of counting, status bit REF2 is set.
Counting IP 240 The following options are available for forcing the output: a) The digital output is to be set when the actual value reaches ”0”, and reset on the first positive GATE signal edge following the start of a new count. In this case, you must set control bits DA1F to 0 and DA1S to 1 in DL 17. b) The digital output is to be reset without regard to the count. In this case, you must set control bits DA1F to 0 and DA1S to 0. c) The digital output is to be set without regard to the count.
IP 240 8.2.4 Counting Flagging with Status Bits Status data is updated in every cycle of the module firmware on the IP. If you want information about the status, you must call control FB 172 and parameterize function 1 ”Read actual value, final value and status bits” ( Section 8.3.2). The CPU then transfers the status bits from the IP to the data block (DW 18, 19 and 27). Status bit AKTV (D 18.5) indicates whether the count has been enabled. It has the same meaning as a set gate signal.
Counting 8.2.5 IP 240 Interrupt Generation and Processing Status bits REF1, REF2, UEBL and UEBS can trigger an interrupt and are stored in the interrupt request bytes on the IP with their positive-going edges as RF1, RF2, UEB and UBS ( Section 8.3.3). Reading the interrupt request bytes After an interrupt request, an interrupt service organization block is called by the CPU. You must call a control FB in this interrupt OB and parameterize ”Read interrupt request bytes” with FCT=3.

IP 240 9 IP 252 Expansion IP 252 Expansion When the IP 240 is used with the IP 252 closed-loop control module, control lines, which are only implemented in the S5-115U programmable controller with a PS 7A/15A power supply, are required to coordinate direct data exchange between the modules. The following explanations for this special mode therefore relate only to the S5-115U programmable controller. 9.
IP 252 Expansion IP 240 By expanding the IP 252 with IP 240 modules, it is possible to provide two or more control loops with actual values from incremental encoders. In these cases, the IP 240 operates as a slave module for the IP 252.
IP 240 9.2 IP 252 Expansion Data Interchange between S5 CPU -- IP 240 -- IP 252 During operation, data traffic between the IP 240 and the IP 252 is controlled by the closed-loop control module. CPU access to the backplane bus is prevented during the data interchange.
1P 252 Expansion 1P 240 — 9.3 Configuring When configuring the 1P 252 closed-loop control module, YOU must W the configuring switches — for speed measurement so that the actual count is interrogated by the 1P 240. Furthermore, during initialization the 1/0 address and the assigned channel of the 1P 240 must also be specified. The 1P 240 is configured by calling function block FB 173 in restart organization blocks OB21 and OB22.

Incremental encoders must be used to generate the path-dependent signals.
Positioning IP 240 10.1.2 Functional Description This section includes a brief description of the IP 240's method of operation in ”positioning” mode and provides explanations of terms used in subsequent sections. Configuring the IP, data interchange The IP 240 is a two-channel module. You can configure one or both channels for ”positioning” mode using configuring function block FB 167. The configuring FB is invoked in the restart organization blocks.

Positioning IP 240 b) Switching and signalling ranges for a position During the approach to a target position, the IP 240 monitors the entry into ranges BEE1 and BEE2 in order to be able to control the drive. Overtravel and standstill of the axis after the drive has been switched off, however, must also be considered. You can define a target range (BEE3) for this purpose. The IP 240 signals entry into and exiting of this range via status bits and interrupts.
Bits BEE1 RICH Example: EWA 4NEB 811 6120-02a Target position 400 700 Traverse range Starting position Range BEE1 900 1000 1100 Range BEE2 aaaaaa aaaaaa -v aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaa aaaaaaaaaaaaaaaaaaaaaaa
Positioning IP 240 b) Approaching the target position in negative direction The axis is at 1600 increments when the position is selected. The axis must travel in the negative direction at the rapid traverse rate. • When the actual value is 1300, the traverse rate is switched to creep speed. • When the actual value is 1100, the drive is switched off. • When the actual value is 1070, the target range has been reached.

IP 240 Positioning To compensate backlash, you can specify that the IP output is to be disabled on a approach to position only when the direction of travel was positive (ascending actual value). If the position was approached in a negative direction, the IP output remains set and the position is ”overrun”. When the BEE2 range is exited, the output must be reset over the S5 CPU (via embedded commands to the IP 240). The position must then be reselected.
Positioning IP 240 c) Synchronization with an external control signal When this method is used, each positive signal edge at the IN input resets the actual value and reactivates the position last selected. Positioning can thus be started in dependence on the IN signal. This method of synchronization is particularly suitable for length measurement, as the current actual value is stored as final value on a negative signal edge at the IN input.
IP 240 Positioning BCD representation If you require BCD-coded data for the purpose of documentation, definition or post-processing, you may choose this form of representation instead of binary. Position numbers and distance values for position 0, however, cannot be represented in BCD. ”1111” is entered in the high-order nibble (half-byte) as the sign (SG) of a negative number. A nibble (also called a half-byte or tetrad) is the term used for the four high-order or the four loworder bits in a byte.
Positioning IP 240 10.3.2 Data in the Data Block and in the Transfer Buffer If the data interchange with the IP 240 • is handled by standard function blocks, you must observe the contents of the data words in the data block when writing and evaluating data. • is programmed as direct data interchange ( Chapter 11), you must observe the contents of the data bytes in the transfer buffer when writing and reading data.

Positioning IP 240 Numerical representation and ranges for input and output values The table below provides an overview of the digit positions actually used and of the ranges for all input and output values. The table also shows, once again, in which cases you need binary and in which cases BCD representation for numerical values. In the column headed ”Configuring parameter” you will find the allocation of the data item to configuring parameter BCD/x or BCD/y.
IP 240 Positioning 10.4.2 Rotary Axis In the case of a rotary axis, the traverse path is closed and is not limited. A revolution can comprise a maximum of 9,999,999 increments. The rotary axis is defined by the following values: • The initial value of the rotary axis is always ”0”. • The final value of the rotary axis points to the same position as the initial value. It must be assigned in the configuration of the IP 240 and may lie between +1 and +9,999,999.
Positioning IP 240 Maximum traversing speed The encoder pulses acquired by the IP are counted in a counter chip. The current (internal) count is read once in every module firmware cycle and is then post-processed to form the (external) actual value. In order for the IP 240 module firmware to ascertain the direction of movement without any ambiguity whatsoever, the change in the actual value between two count readouts (tLZ) must be less than the halved final value for the rotary axis (tLZ max.·v max.<0.
IP 240 10.5 Positioning Switching the IP Outputs The IP 240 is equipped with two digital outputs (D1 and D2) for each channel. You have two options for influencing setting and resetting of the IP outputs: • • You can determine the switching performance of the IP outputs when you configure the channel. Depending on the application, you can control either the direction of travel or the traversing speed directly via the IP outputs.
Positioning IP 240 10.5.2 The IP Outputs Control the Traversing Speed When you configure DAV=0 or DAV=1, you pass control of the traversing speed to the IP outputs. The outputs are switched without regard to the direction of travel. a) Outputs are set separately (DAV=0) After the target position has been selected ( Fig. 10-12a: Actual value 1000), the IP 240 sets output D1 in dependence on the actual value. When range BEE1 is entered (actual value 2000), output D1 is reset and output D2 set.

IP 240 10.6 Positioning Backlash Compensation (LOSE) Backlash in the position decoding system reduces the positioning accuracy. To prevent this, all positions and the reference point must always be approached from the same direction. The IP 240 supports this when you configure ”Backlash compensation”. Configuring backlash compensation You can specify backlash compensation by setting the ”LOSE” parameter to ”1”: NAME LOSE : JU FB 167 : STRU.
Positioning IP 240 If the actual value is greater than the position value of a newly selected position, the positioning procedure must be subdivided into two steps: 1st step Select position ( Fig. 10-15: Actual value 9300). The drive is switched on and moves at rapid traverse speed in a negative direction toward the target position. The speed is switched to creep at the right BEE1 switching point (actual value 7400).
IP 240 Positioning 10.6.2 Backlash Compensation during Reference Point Approach Compensation of the backlash during reference point approach ( Section 10.13.1) is similar to compensation during positioning. Synchronization is attained only when the reference point is approached in a positive direction. Decisive for evaluation of the direction is the instant at which the preliminary contact signal (connected to the IP's IN input) changes back to zero.
Positioning IP 240 Actual value range and overrange The actual value range is defined as -9,999, 999 to +9,999,999. - 9,999,999 to - 1 0 - 9,999,999 Overrange to -1 0 + 1 to 9,999,999 Defined actual value range 0 + 1 to 9,999,999 Overrange Fig. 10-17. Actual Value Range and Overrange in Positioning Mode When the defined actual value range is exited, the counter enters the overrange and the IP 240 sets the UEBL bit.

Positioning IP 240 10.7.2 Zero Offset By transferring a zero offset (NVER), you can allocate a new actual value to the current position. You may also make a distinction as to whether or not actual-value matching should take the last (old) zero offset that was transferred into account. The specified zero offset is taken into account when the actual value is computed and during synchronization of the actual value.
IP 240 Positioning b) Additive zero offset The new actual value is computed as follows when you specify an additive zero offset: Actualnew=Actualold + Zero offsetadd.,new The actual value thus changes by the value of the additive zero offset transferred.

IP 240 10.8 Positioning Position Data for Positions 1 to 254 Position data includes: • the position value designating the absolute location of the position in the traversing range, • the position number, which you use to select a position, • the distance values of the switching and signalling ranges. Position data for a total of 254 positions can be stored on the IP for each channel. The distance values for the switching and signalling ranges apply to all positions.
Positioning IP 240 Entering the position numbers and position values in the data block The area beginning with DW 60 is reserved for position numbers and position values. The number of positions determines the length of the data block ( Section 10.23.1). If you need more than 65 positions, then you also need more than 256 data words in the DB. Observe carefully the restrictions applying to processing of data words beyond DW 255 ( Section 10.24).
IP 240 Positioning The position number assigned to a position need not be identical to the number of the position entry. It is more practical, however, for the two to be identical, particularly when you want to change a position value with control FB 168 after configuring ( Section 10.18.1), as the number of the position entry, not the position number itself, must be specified in the control FB. 10.8.
Positioning IP 240 When the actual value is within a range, the associated status bit BEE1, BEE2 or BEE3 is set to zero.
IP 240 Positioning Transferring the distance values with the configuring FB The distance values are initially transferred to the IP 240 when you configure the channel. Before invoking FB 167, you must enter the distance values in the data block. The distance value in data words 50 and 51 is for range BEE1, the distance value in data words 52 and 53 for range BEE2, and the distance value in data words 54 and 55 for range BEE3.
Positioning IP 240 Zero mark monitoring Zero mark monitoring is used to detect spurious or missing pulses, and is possible only when • the number of encoder pulses between two zero marks (Z signals) is divisible by 4 or 5 without a remainder, • the timing of the zero mark signal satisfies the conditions discussed in Section 13.1 ”Signal Forms and Timing Requirements for Incremental Encoders” and • a reference point approach was terminated with synchronization.
IP 240 Positioning 10.10 Initializing the Parameters for Interrupt Generation (PRA1, PRA2, ABIT) The following status bits have interrupt capability, and can trigger an interrupt on the S5 CPU when they go to ”1” or ”0”. The associated interrupt bit is also set in the interrupt request bytes.
Positioning IP 240 When using an S5-150U or S5-155U (150 mode), note that the ABIT parameter must also be initialized. In these programmable controllers, an interrupt service OB is invoked at the next block boundary when the associated bit in PY 0 (I/O byte 0) changes its signal state. By initializing the ABIT parameter accordingly, you can indicate whether the interrupt service OB is to be invoked every time the signal state of the interrupt bit changes, or only when the bit goes from ”0” to ”1”.

Positioning 10.13 IP 240 Methods of Synchronization Positioning is possible with the IP 240 only when the actual value has been synchronized. Three methods of synchronization are available for this purpose: • Reference point approach A reference point approach synchronizes the actual value to a fixed point in the traversing range. • Software-controlled synchronization The actual value is synchronized every time a control bit with a value of ”1” is transferred.

Positioning IP 240 Switching the IP outputs during reference point approach (HAND=0) The switching performance of the IP outputs specified when the channel was configured is taken into account during reference point approach. a) DAV=0 (switch outputs separately) After the outputs have been enabled (FREI=1), IP output D1 is set. When the preliminary contact signal is reached (positive edge at the IN input), output D1 is reset and output D2 set. D2 is reset when the reference point is reached.
IP 240 Positioning c) DAV=2 After the outputs have been enabled, the IP output specified by setting control bit DA1S or DA2S is set. The output is reset when the reference point is reached.
Positioning IP 240 Status of range bits BEE1, BEE2 and BEE3 during reference point approach When reference point approach is selected, all three range bits (BEE1, BEE2 and BEE3) are set to ”1”. Bit BEE1 is set to ”0” when the preliminary contact is reached. It remains at ”0” until the preliminary contact is exited and the status area on the IP 240 has been read at least once. You can control the switch to creep speed by evaluating status bit BEE1 ( Section 10.16).
IP 240 Positioning Interrupting a reference point approach You can interrupt a reference point approach by transferring • control bit HASY = 0 or • control bit FREI = 0 to the IP 240. When the reference point approach is interrupted with HASY=0 and FREI=1, the IP outputs are disabled only when they are are under IP 240 module firmware control during reference point approach (HAND=0).
Positioning IP 240 The new position number can be transferred to the IP 240 together with SOSY=1. Refer to Section 10.14.1 for information on how to select a position number. If there is to be no software-controlled synchronization, you must set SOSY to ”0” prior to the next transfer of the control bits.
IP 240 Positioning 10.13.3 Synchronization with an External Control Signal When synchronization with an external control signal, referred to from here on as ”cyclic synchronization”, is used, the IP 240 evaluates the edge change at the IN input. On a positive signal edge (signal change from 0 to 1) at this input, the actual value is set to the value of the zero offset and the position last selected reactivated.

Positioning IP 240 If it is necessary to disable the IP outputs, you can do so by transferring FREI=0 and, at the same time, specify the new position number (thus combining steps 2 and 3). If it is not necessary to disable the IP outputs, you can omit step 2 and transfer the new position number together with control bits FREI=1 and HAND=0 (thus combining steps 3 and 4). In this case, however, the module sets the outputs immediately in dependence on the actual value.

Positioning 10.19 IP 240 Interrupting Positioning and Skipping of a Position Positioning is interrupted when • control bit FREI=0 is transferred. In this case, the outputs are disabled but the old position number is retained. If the actual value changes (e.g. due to transfer of a zero offset), the status bits are matched to this position number and any pending interrupts generated in dependence on the actual value. You can enable the outputs by transferring FREI=1.

Positioning IP 240 10.25 Example: Removing Parts from a Die-Casting Machine aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa Finished parts are to be taken from a die-casting machine and deposited at various positions. This example concentrates on positioning of one of the three axes. When the setpoint is reached, an interrupt is generated, thus enabling a gripper. The traversing speed (rapid traverse or creep speed) is set directly via the IP's digital outputs.

The IP 240 sets the DFRT bit in the status register when the requested data are available in the transfer buffer. In order to prevent errors in a data interchange between IP 240 and S5 CPU, interrupt processing must be disabled while the data interchange is in progress.

IP 240 12 Response Times Response Times The response time is the time between reaching of a setpoint and the IP 240's reaction. The signals from the incremental encoders or pulse encoders are acquired by counter chips. These counter chips make an internal count available which is read and evaluated in each module firmware (FW) cycle. IP inputs IN and GT are also sensed at the hardware level and postprocessed by the firmware.
Response Times 12.2 IP 240 Computing the Response Time Using channel 1 as example, Figure 12-2 shows which FW slices must be taken into account when computing the response time. Channel 1 setpoint reached.

A Adapter Casing (S5 Adapter) In this Chapter In this chapter, you will learn how to install modules in the adapter casing, and what you must observe when using the various S5 modules. Section IP 240 EWA 4NEB 811 6120-02b Contents Page A.1 Prerequisites A-2 A.2 Installing an Adapter Casing in the S7-400 A-3 A.3 Inserting S5 Modules in an Adapter Casing A-4 A.4 Interrupt Processing A-5 A.
Adapter Casing (S5 Adapter) A.1 Prerequisites General The following prerequisites must be observed as regards the use of S5 modules in the S7-400: Check with your local Siemens office that the modules you want to use have been approved for implementation. Programmable S5 modules can be linked into a STEP 7 user program only with special standard function blocks.
Adapter Casing (S5 Adapter) A.2 Installing an Adapter Casing in the S7-400 Introductory Remarks To install an S5 module in an S7-400, you must first install the adapter casing in the S7 rack, then set the address on the S5 module, and, finally, insert the module in the adapter casing. Installing the Adapter Casing in a Rack Proceed as follows to install an adapter casing in a rack: 1. Check to make sure that the jumpers on the back of the adapter casing are closed (factory setting).
Adapter Casing (S5 Adapter) A.3 Inserting S5 Modules in the Adapter Casing Procedure Proceed as follows to insert an S5 module in the adapter casing: 1. Set an interrupt circuit on the module, which sets the destination CPU for interrupts (in the case of interrupt-generating modules only). Interrupt Circuit... ... Corresponds to Destination CPU /INT A CPU 1 /INT B CPU 2 /INT C CPU 3 /INT D CPU 4 2. Unscrew and remove the interlocking plate on the adapter casing. 3.
Adapter Casing (S5 Adapter) A.4 Interrupt Processing Introductory Remarks The adapter casing converts S5 interrupts into S7 interrupt functions and interrupt signals. Interrupt Routing All of the S5 module’s interrupts are forwarded as (S7) process interrupts.

Addressing S5 Modules (Adapter Casing and IM 463-2) In this Chapter B This chapter describes how to address S5 modules inserted in the adapter casing, and how to address S5 modules connected via the IM 463-2. Section B.
Addressing S5 Modules B.1 Addressing S5 Modules Introductory Remarks There are two ways of using an IP xxx S5 module in the S7-400: By installing it in the adapter casing in the S7 central rack By using an S5 expansion rack and connecting the S5 module via the IM 463-2 interface module in the S7 central rack and the IM 314 interface module in the S5 expansion rack.
Addressing S5 Modules S5 Address Areas S5 modules in the S7-400 may be addressed in the following addressing areas: I/O area (P area) Extended I/O area (Q, IM3, IM4) Page area I/O Area A PESP signal (that is, a memory I/O select signal) is generated in the P area only when S5 modules are interfaced to the system via the adapter casing. The signal is forwarded to the S5 module. No PESP signal is generated for the Q, IM3 or IM4 areas.
Addressing S5 Modules Example of Addressing in the Page Area The CPU and an IP (an IP being an intelligent I/O module) interchange data via the S5 bus interface and a 2 Kbyte dual-port RAM which is divided into two “pages”. The addressing area in which the pages are located is set at the factory. You need only set the page number for the first page on the module. A module’s two pages always reserve two consecutive numbers. The IP thus knows the address for the second page automatically.

IP 240 3 Addressing Addressing The IP 240 module reserves an address space of 16 bytes in the I/O areas. All data are exchanged via these areas, which can be read out and written to by the S5 CPU. The data transfer is handled by a standard function block. It is merely necessary to set the desired starting address and the I/O area (P or Q area) via coding switches on switchbanks S2 and S3 on the module.

IP 240 5 Operation Operation Before startup you must set various coding switches on the module. You can stipulate • interrupt generation with switchbanks S1 and S2 ( Section 5.1) • disabling of the digital outputs with switchbank S4 ( Section 5.2) • encoder signal matching with switchbanks S5 and S6 ( Section 5.3) The locations of the switchbanks and the fuses are shown in Fig. 5-1. The switch settings in the figure are factory setttings.
Operation 5.1 IP 240 Settings for Interrupt Generation The processing of interrupt signals makes it possible to respond rapidly to status changes. In the SIMATIC S5 programmable controllers, a distinction is made between two types of interrupts: • ”Servicing IRx interrupt circuits” (S5-115U, S5-135U and S5-155U in the 155U mode) • ”Reading I/O byte 0” (S5-150U and S5-155U in the 150U mode). 5.1.
IP 240 Operation If several IP 240 modules use one interrupt circuit, the current interrupt source must be determined by reading the interrupt request bytes of all modules or by additonally evaluating I/O byte 0. This must be taken into account in the STEP 5 program due to the system characteristics of the S5-115U CPUs ( Section 5.1.2). Note • • • • 5.1.2 In the S5-115U, S5-135U and S5-155U, only one of the coding switches S2.1 to S2.4 may be closed at any given time.

Allocation of Coding Switches on Switchbanks S1 and S2 to Interrupt Generation with I/O Byte 0 The coding switches on banks S1 and S2 shown in Fig. 5.3 have the following meaning: on: The corresponding bit of I/O byte 0 is set in response to an interrupt signal on the I/O module.
IP 240 Operation Example for setting the coding switches Three IP 240s are to be enabled for interrupt generation. One IP 240 is to be operated as master module and the other two as slave 1 and slave 2. Slave 1 is assigned to PY 0.1 and slave 2 to PY 0.2. Bits PY 0.3 to PY 0.6 are reserved by other modules. PY 0.7 is not used and must be masked on the master module or else OB9 must not be programmed.
