Technical Description and Installation Instructions 1 This chapter outlines the basic functions of the CP 243-2 and explains how the module is installed and started up.
Technical Description and Installation Instructions 1.1 ! ! ! General Notes on Operation – Safety Warnings Caution When handling and installing the CP 243-2, make sure that you keep to the ESD guidelines. The CP 243-2 must only be connected when the AS-i power supply unit is turned off. Caution Noise immunity/grounding To ensure the noise immunity of the CP 243-2, the CP 243-2 and the AS-i power supply unit must be correctly grounded.
Technical Description and Installation Instructions 1.2 Uses of the Module DP Slave and AS-i Master The CP 243-2 module can be operated in the S7-200 programmable controller. It allows the attachment of an S7-200 to the AS-Interface (as AS-i master). Both interfaces can be used independent of each other.
Technical Description and Installation Instructions Components Supplied The CP 243-2 product includes the following components: CP 243-2 Product information bulletin on the CP 243-2 1-4 SIMATIC NET CP 243-2 AS-i Master C79000-G8976-C142/02
Technical Description and Installation Instructions 1.
Technical Description and Installation Instructions 1.4 Installing the Module Slots in the S7-200 The CP 243-2 can be inserted in all slots for expansion modules in the S7-200 programmable controller (CPUs 22x).
Technical Description and Installation Instructions 1.5 Front Panel – Access to all Functions Connection, Display and Control Elements On the front panel, you have access to all the connection, display and control elements of the CP 243-2. During operation, the connection and control elements are protected by a front cover.
Technical Description and Installation Instructions 1.6 Terminal Block Connections The CP 243-2 has the following connections: Two connections to the AS-i cable (bridged internally) One connection for functional ground The terminals are located under the cover of the front panel of the CP 243-2. AS-i cables Figure 1-3 Functional ground Connecting the AS-i Cable Connections to the AS-i Cable The CP 243-2 has two connections for AS-i cables that are jumpered internally on the CP 243-2.
Technical Description and Installation Instructions Note Functional ground (terminal ) The CP 243-2 has a connection for functional ground. This connector should be connected to the PE conductor with as little resistance as possible.
Technical Description and Installation Instructions 1.7 Modes of the CP 243-2 Standard Operation In this type of operation, the user program accesses the user data of the AS-i slaves and the diagnostic data of the CP 243-2. Programming is simple and this type of operation is adequate for the majority of automation tasks. In standard operation, no commands or special parameters are transferred to the slaves. This type of operation corresponds to the profile M0 of the AS-i master specification.
Technical Description and Installation Instructions 1.8 Displays and Operator Controls Changing the Display Status – DISPLAY Button You can change between the status display (basic status), slave display and PROFIBUS display with the DISPLAY button. Each time you press the button, you change to the next display status finally returning to the initial status. In the slave display, the slaves on the AS-Interface are displayed in groups of 5 slaves.
Technical Description and Installation Instructions 1.8.1 Status Display Interpreting the Status Display The status display is active when no group LEDs are lit. The status display is the default display in the basic status of the CP 243-2. Meaning of the LEDs The LEDs have the following meaning: Table 1-2 LED (color) CM (yellow) Status Configuration Mode Meaning This displays the operating mode of the CP 243-2.
Technical Description and Installation Instructions Table 1-2 , continued LED (color) SF (red) Status System error Meaning This LED is lit in the following situations: The CP 243-2 has detected an internal problem (for example a defective EEPROM). The CP 243-2 is unable to make the currently required mode change (for example an AS-i slave with address 0 exists) when a button is pressed.
Technical Description and Installation Instructions 1.8.2 Slave Display Interpreting the Slave Display Status You can switch over to the slave display mode used by pressing the DISPLAY button. You switch from group to group by pressing the DISPLAY button again: The slave display is active when at least one group LED is lit. Characteristics of the Slave Display If the CP 243-2 is in the configuration mode, all detected AS-i slaves are displayed.
Technical Description and Installation Instructions Example of a Slave Display From the display shown below, you can obtain the following information: The 2nd group LED is lit, i.e. the 2nd line from the top (corresponds to 21 = 2DEC; 2. group of 5; slaves 5–9). If the 2nd and 4th LEDs are also lit within the slave display, this means that slaves 6 and 8 are active. If the “B” LED is also lit, then in this example, this would mean that slaves 6B and 8B are active.
Technical Description and Installation Instructions 1.9 Configuring the AS-Interface with the SET Button Interpreting the Display Status The CP 243-2 distinguishes between two operating modes on the AS-Interface: Configuration mode Protected mode Pressing the SET button changes the operating mode. Note The SET button is only effective when the bit PLC_RUN = 0 is set in the control byte of the CP 243-2. This is always the case when the S7-22x CPU is in the STOP mode.
Technical Description and Installation Instructions Note Changing from the configuration mode to the protected mode is only possible when there is no slave with address “0” connected to the AS-Interface. If a slave “0” is connected, the “SF” LED lights up when the SET button is pressed. Preparing to Configure Make sure that the following situation applies: The S7-22x CPU must be set to STOP (PLC_RUN=0).

Banks 16–30: Reserved area These areas are reserved for later expansions and cannot be used.
Access to the Data of the AS-i Slaves 3 This chapter explains the AS-i master interface of the CP 243-2. The first part covers addressing the AS-i slaves and access to the binary data of the slaves. In the second part, addressing and access to the analog data of the AS-i slaves is explained.
Access to the Data of the AS-i Slaves 3.1 Access to the Binary Data of the AS-i Slaves 3.1.1 Addressing the AS-i Slaves in the User Program Requirements Before you can access the I/O data of the AS-i slaves, the following requirements must be met: Deactivate the filtering of the analog inputs for the CP 243–2 in the system data block of the S7–200 CPU. Set the “PLC_RUN” bit (bit 7) in the digital control byte to ’1’ at the beginning of the cyclic program.
Access to the Data of the AS-i Slaves Assignment of the AS-i Input Data of the Standard or A Slaves (Bank 0 in the Analog Input Area of the CP) Bank Byte no.
Access to the Data of the AS-i Slaves Assignment of the AS-i Input Data of the B Slaves (Bank 31 in the Analog Input Direction of the CP) Bank Byte no.
Access to the Data of the AS-i Slaves Data Exchange in the STOP Mode of the S7-22x CPU In the STOP mode, the S7-22x CPU sets bit PLC_RUN in the digital control area to “0” automatically. As a result, the CP 243-2 outputs “0” data to all binary slaves. Special Feature of Analog Slaves If you use analog slaves complying with profile 7.3 or 7.4 the following points apply: In the input direction, the CP 243-2 sets the nibbles assigned to the slaves to “0”.
Access to the Data of the AS-i Slaves Example Figure 3-1 shows an example of the CP 243-2 addressing four AS-i slaves. In the example, m = 0 is the start address for the input data and n = 0 is the start address for the output data. The bits relevant for the user program (existing AS-i slaves) are shown on a gray background. The bits on a white background are irrelevant for the user program.

Access to the Data of the AS-i Slaves 3.1.2 Access to the AS-i User Data Data Access with STEP 7 Micro To access the binary data of the slaves, you use the analog transfer commands of the STEP 7 Micro/WIN32 programming language. Example If you want to access individual bits of the slave data, you can use the method shown in the following sample program. The example created with STEP 7 Micro/WIN32 is valid for a CPU 222 with a CP 243-2 plugged in directly beside it: OB1 (STL) NETWORK 1 LD SM0.1 SI Q1.
Access to the Data of the AS-i Slaves 3.2 Access to the Analog Data of the AS-i Slaves (Slaves complying with Profile 7.3 or 7.4) 3.2.1 Addressing the Analog AS-i Slaves in the User Program Requirements Before you can access the I/O data of the AS-i slaves, the following requirements must be met: Deactivate the filtering of the analog inputs for the CP 243–2 in the system data block of the S7–200 CPU.

For further information about the range of values, measuring range, accuracy etc., refer to the relevant documentation of the analog slaves.
Access to the Data of the AS-i Slaves 3.2.2 Access to the AS-i Analog Data Data Access with STEP 7 Micro You access the analog data of the AS-i slaves using the analog commands of the “STEP 7 Micro/WIN32” programming language. Example The following example shown in STL is valid for a CPU 222 with a CP 243-2 plugged in directly beside it. The program reads the analog input value of slave 3 (channel 2) cyclically and sends it to the analog output slave 16 (channel 1). OB1 (STL) NETWORK 1 LD SM0.1 SI Q1.

Signaling Errors and Diagnostics in the User Program 4 This chapter explains which errors of the CP 243-2 are signaled and how to read out the Delta list.
Signaling Errors and Diagnostics in the User Program 4.1 Signaling Error Signaling If the CP 243-2 recognizes errors on the AS-Interface (AS-i slave failure, AS-i Power Failure) during operation, it signals these errors by resetting the input data of the affected slave and by setting the corresponding bit in the error register in the SM area (Special Memory). The SM byte addresses depend on the slot of the CP 243-2.
Signaling Errors and Diagnostics in the User Program 4.2 Example: Reading the Delta List STL Example The following example in STL applies to a CPU 222 with a CP 243-2 plugged in directly beside it: If an AS-i configuration error occurs in the protected mode, the CP 243-2 sets bits SM 9.0 and SM 11.0 (both bits provide the user with the same information: AS-i configuration errors).

Command Interface 5 Via the command interface, you can control the response of the AS-i master completely from within your user program. This chapter introduces you to the AS-i command interface and the AS-i commands. You require the AS-i command interface when you want to use functions over and above pure I/O data exchange with the AS-i slaves (for example assigning parameters to slaves from within the S7-200 program, modifying slave addresses etc.).
Command Interface 5.1 Command interface of the CP 243-2 Command Buffer and Response Buffer Command calls are made to the CP 243-2 from within the user program. You specify the command call in a command buffer and start the job. The command buffer is in the analog output area of the CP 243-2 (for example starting at AQW0 if the CP 243-2 is plugged in directly beside an S7-200 CPU). Depending on the command to be executed (see Section 5.
Command Interface Command Sequence The diagram below shows the following: How to execute commands in the user program How the CP 243-2 reacts to a command AS-i master (user program) CP 243-2 (reaction to command) Set command parameter in the analog output area Initial status Initial status ASI_COM bit = 0 ASI_RESP bit = 0 ASI_COM bit = 0 ASI_RESP bit = 0 Start command Set ASI_COM bit = 1 Wait for response Receives command Executes command ASI_RESP bit = ?

Command Interface A command started by the CP 243-2 is executed completely regardless of the state of the ASI_COM bit. The ASI_RESP bit is only reset by the CP 243-2 when the user program has set the ASI_COM bit to “0”.

Command Interface General Structure of the Command Buffer Depending on the command, the command buffer can extend over a maximum of 14 banks (bank 2–15 in the analog module) with a maximum of 224 bytes. In the following description of the command interface, the start address 0 is assumed for the analog input module of the CP to simplify byte numbering.
Command Interface General Structure of the Response Buffer Depending on the command, the response buffer can extend over a maximum of 14 banks (bank 2–15 in the analog module) and a maximum of 224 bytes. In the following description of the command interface, the start address 0 is assumed for the analog output module of the CP to simplify byte numbering.
Command Interface Command Status Whether or not the job was executed correctly or errors occurred is signaled in the command status of the response buffer in byte 1. Table 5-6 Meaning Value 00 H Job completed without error 81 H The AS-i slave address is incorrect 82 H The AS-i slave is not activated (not in LAS). 83 H Error on AS-Interface. 84 H Command not permitted in the current status of the AS-i master. 85 H An AS-i slave with address 0 exists.
Command Interface General Structure of the AS-i Slave Address If an AS-i slave is addressed in a command or in a reply, the address is structured as shown below: Bit 7 Bit 5 Bit 4 S bit Bit 3 Bit 0 Slave address Where the S(elect) bit for selecting the slave type is specified as follows: S bit = 0 Standard AS-i slave or AS-i slave with extended addressing mode in address area A S bit = 1 AS-i slave with extended addressing mode in address area B 5-12 SIMATIC NET CP 243-2 AS-i Master C79000-G8976-C1
Command Interface 5.2.1 Set_Permanent_Parameter Purpose With this call, a parameter value for the specified AS-i slave is transferred to the CP 243-2 . The value is saved permanently as a configured value. The configured parameter is not transferred immediately to the AS-i slave by the CP 243-2. The configured parameter value is only transferred when the AS-i slave is activated after turning on the power supply on the CP 243-2.
Command Interface 5.2.2 Get_Permanent_Parameter Purpose With this call, a slave-specific parameter value stored on the EEPROM of the CP 243-2 is read.
Command Interface 5.2.3 Write_Parameter Purpose of the Command The AS-i parameter value transferred with the command is passed on to the addressed AS-i slave. The parameter is stored on the CP 243-2 only temporarily and is not entered as a configured parameter in the EEPROM! The AS-i slave transfers its current parameter value in the reply (parameter echo). This can deviate from the value that has just been written according to the AS-i master specification (/2/).
Command Interface 5.2.4 Read_Parameter Purpose This call returns the current parameter value (actual parameter) of a slave. This value must not be confused with the parameter echo that is supplied by the AS-i slave as a reply to the write_parameter job.
Command Interface 5.2.5 Store_Actual_Parameters Purpose This call overwrites the permanently stored configured parameters with the actual parameters, in other words the parameters are reconfigured. For AS-i slaves that comply with the AS-i slave standard profile 7.4, the AS-i master manages the AS-i slave parameter assignment itself. The configured parameters for these AS-i slaves always have the value F H.
Command Interface 5.2.6 Set_Extended_Permanent_Configuration Purpose This call sets the following configuration data for the addressed AS-i slave. I/O configuration ID code Extended ID1 code Extended ID2 code The configuration data are stored permanently on the EEPROM of the CP 243-2 and are used as the expected configuration by the AS-i master in the protected mode. The configuration data are specified by the manufacturer of the AS-i slave. The meaning of the configuration data is described in /2/.
Command Interface 5.2.7 Get_Extended_Permanent_Configuration Purpose This call reads the following configuration data (configured data) of an addressed AS-i slave stored on the EEPROM of the AS-i master. I/O configuration ID code Extended ID1 code Extended ID2 code The configuration data are specified by the manufacturer of the AS-i slave. The meaning of the configuration data is described in /2/.
Command Interface 5.2.8 Store_Actual_Configuration Purpose of the Command With this call, the (actual) configuration data (I/O configuration, ID code, extended ID1 code and extended ID2 code) of all AS-i slaves are stored permanently in the EEPROM as the (expected) configuration data. The list of activated AS-i slaves (LAS) is adopted in the list of permanent AS-i slaves (LPS).
Command Interface 5.2.9 Get_Extended_Actual_Configuration Purpose of the Command With this call, the following configuration data of an addressed AS-i slave obtained by the AS-i master on the AS-Interface are read. I/O configuration ID code Extended ID1 code Extended ID2 code The configuration data are specified by the manufacturer of the AS-i slave. The meaning of the configuration data is described in /2/.
Command Interface 5.2.10 Set_Extended_LPS Purpose With this call, the list of configured AS-i slaves is transferred for permanent storage in the EEPROM. When this command is executed, the AS-i master changes to the offline phase and then changes back to the normal mode (warm restart on the AS-i master). The call is not executed in the protected mode.
Command Interface 5.2.11 Set_Offline_Mode Purpose This call switches between the online and offline mode. The online mode is the normal situation for the CP 243-2. Here, the following jobs are processed cyclically: During the data exchange phase, the fields of the output data are transferred to the slave outputs for all slaves in the LAS. The addressed slaves transfer the values of the slave inputs to the master when the transfer was free of errors.
Command Interface 5.2.12 Select_Autoprogramming Purpose This call can enable or disable the “automatic address programming” function (see also Section 6.1). The AUTO_ADDR_ENABLE bit is stored permanently; in other words it is retained after a warm/hot restart on the AS-i master.
Command Interface 5.2.13 Set_Operation_Mode Purpose of the Command With this call, you can select between the configuration mode and the protected mode. In the protected mode, only AS-i slaves are activated that are entered in the LPS and whose expected and actual configurations match, in other words when the I/O configuration and ID codes of the detected AS-i slaves are identical to the configured values. In the configuration mode, all detected AS-i slaves (except for slave address “0”) are activated.
Command Interface 5.2.14 Change_AS-i_Slave_Address Purpose of the Command With this call, the address of an AS-i slave can be modified. This call is mainly used to add a new AS-i slave with the default address 0 to the AS-Interface. In this case, the address is changed from the old slave address (0) to the new slave address. This change can only be made when the following conditions are fulfilled: 1. A slave with the “old slave address” exists. 2.
Command Interface 5.2.15 Get_AS-i_Slave_Status Purpose With this call, the status register of the addressed AS-i slave can be read out. Depending on the type of AS-i slave, the flags of the status register have the following meaning: Status Bit AS-i slave complying with standard 2.0 S0 Address volatile S1 This flag is set when the internal AS-i slave routine for permanent storage of the AS-i slave address is active. This can take up to 15 ms and must not be interrupted by a further addressing call.

AS-Interface Protocol Implementation How the AS-Interface cycle time depends on the number of connected slaves The following formula is used to calculate the AS-Interface cycle time depending on the number of activated slaves. Tcycl = (1 + number of activated slaves) * 156µs If a pair of slaves using the extended addressing mode (A/B slaves) occupies an address, this pair is counted as a single slave in the formula.

Glossary APF AS-i Power Fail. Flag or LED display that indicates that the power supply on the AS-i cable is too low or has failed (for example failure of the AS-i power supply unit). AS-i (AS-Interface) Actuator-sensor interface. A network system for the lowest field area of the automation range. It is suitable for networking sensors and actuators with control devices. (previously: SINEC S1) AS-i A/B slave AS-i A/B slaves use the extended addressing mode.
Glossary AS-i module For the AS-Interface, a module concept has been defined that allows the blocklike linking of AS-i slaves – sensors and actuators – via AS-i modules. The following types of module exist: The active AS-i module with an integrated AS-i chip; using this, up to four conventional sensors and actuators can be connected. The passive AS-i module; this functions as a distributor and provides a connection for up to four sensors and actuators with an integrated AS-i chip.
Glossary Nibble A nibble is a unit of information consisting of four bits. Standard AS-i master Up to 31 standard slaves or slaves with the extended addressing mode (A slaves only) can be attached to a standard AS-i master.
