TIP The Pico GFX-70 devices run a system test for one second after the power supply has been switched on. Either RUN or STOP mode will be activated after this time depending on the default setting. 1760-IA12XOW6I Expansion Units Figure 2.
2-18 Installation DC Power Supply for the GFX-70 Figure 2.18 Power supply on the GFX L02+ L01+ L01– >1A +24V 0V 0V The GFX processor unit supplies the necessary power supply to itself, the display, the input/output electronics, the expansion I/O, and optionally the Pico-Link cable. IMPORTANT Publication 1760-UM002B-EN-P - March 2005 The GFX device processor unit is protected against reverse polarity. Ensure the correct polarity of the terminals to ensure that the GFX functions correctly.
Installation 2-19 1760-IB12XOB8 Expansion Module Figure 2.19 Power supply on the DC expansion units L01+ L01F1 E+ E- IMPORTANT R1 ... R12 24V 0V 0V 24 V The module is protected against polarity reversal. To ensure that module works correctly, ensure that the polarity of each terminal is correct. Cable Protection Provide cable protection (F1) for at least 1A (slow). IMPORTANT When the expansion I/O or the GFX is switched on for the first time, its power supply circuit behaves like a capacitor.
2-20 Installation Connecting the Inputs The inputs switch electronically. Once you have connected a contact via an input terminal, you can reuse it as a contact in your Pico GFX-70 circuit diagram as often as you like. Figure 2.20 Connecting the inputs L +24 V S1 N 0V I1 I1 i1 Connect contacts such as push button actuators or switches to the input terminals.
Installation 2-21 Figure 2.21 1760-IA12XOW6I Expansion unit L1 N F1 E+ E– R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 L N N 100-240 V Connect the inputs, for example, to push button actuators, switches or relay/contactor contacts. Input signal voltage range • OFF signal: 0V ac to 40V ac • ON signal: 79V ac to 264V ac Input current • R1 to R12 0.5 mA/0.25 mA at 230V ac/115V ac Cable Lengths Severe interference can cause a “1” signal on the inputs without a proper signal being applied.
2-22 Installation Figure 2.22 1760-IB12XOB8 with a diode on the inputs L1 N F1 E+ E– R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 L N N 100-240 V Two-wire proximity switches have a residual current with the “0” state. If this residual current is too high, the input may detect a “1” signal. If inputs with a higher input current are required, an additional input circuit must be used.
Installation IMPORTANT 2-23 When using a 100 nF capacitor, the drop-out time of the input increases by 80 (66.6) ms at 50 (60) Hz. A resistor can be connected in series with the circuit shown in order to restrict the inrush current. Figure 2.
2-24 Installation Figure 2.25 GFX DC L01+ L02+ L01– >1A +24V 0V 0V IMPORTANT I1 I2 I3 I4 I5 I6 I7 I8 I9 I10 I11 I12 The digital inputs must have the same voltage as the power supply of the GFX. Figure 2.
Installation 2-25 Connecting Analog Inputs Inputs I7, I8, I11 and I12 can also be used to connect analog voltages ranging from 0V dc to 10V dc. The following applies: • • • • I7 = IA01 I8 = IA02 I11 = IA03 I12 = IA04 The resolution is 10-bit = 0 to 1023. ATTENTION Analog signals are more sensitive to interference than digital signals. Consequently, more care must be taken when laying and connecting the signal lines. Incorrect switching states may occur if they are not connected correctly.

Installation ATTENTION ATTENTION 2-31 Outputs may only be connected in parallel within a group (Q1 to Q4 or Q5 to Q8, S1 to S4 or S5 to S8), such as Q1 and Q3 or Q5, Q7 and Q8. Outputs connected in parallel must be switched at the same time. Please note the following when switching off inductive loads: Suppressed inductive loads cause less interference in the entire electrical system. For optimum suppression the suppressor circuits are best connected directly in the proximity of the inductive load.
2-32 Installation Connecting Analog Outputs 1760-IB12XOW4IOF and 1760-IB12XOB4IOF each have an analog output QA 01, 0V dc to 10V dc, 10 bit resolution (0 to 1023). The analog output allows you to control servo valves and other final controlling elements. ATTENTION Analog signals are more sensitive to interference than digital signals. Consequently, more care must be taken when laying and connecting the signal lines. Incorrect switching states may occur if they are not connected correctly.

The last coil in the circuit diagram determines the status of the relay.
Wiring with Pico GFX-70 4-35 A coil is automatically switched off if the power fails and if STOP mode is active. Exception: Retentive coils retain signal 1 (see Retention on page 7-22). “Set” S and “Reset” R Coil Function The “Set” S and “Reset” R coil functions are normally used in pairs. The relay picks up when the coil is set (A) and remains in this state until it is reset (B) by the coil function. The supply voltage is switched off (C), the coil does not have a retentive effect. Figure 4.
4-36 Wiring with Pico GFX-70 Coil Negation (Inverse Contactor Function) ] The output signal is simply an inversion of the input signal; the relay operates like a contactor with contacts that have been negated. If the coil is triggered with the 1 state, the coil switches its make contacts to the 0 state. Figure 4.22 Signal diagram of inverse contactor function on on Rising Edge Evaluation (Cycle Pulse) , If the coil is only meant to switch on a rising edge, this function will be applied.

Wiring with Pico GFX-70 4-39 – single pulse – synchronous flashing – asynchronous flashing • Set cycle time • Value limitation The following applies to function blocks: IMPORTANT The most recent actual values are cleared if the power supply is switched off or if Pico GFX-70 is switched to STOP mode. Exception: Retentive data keeps its state (see Retention on page 7-22). The most recent actual values are transferred to the operands every cycle. The data function block is an exception.
4-40 Wiring with Pico GFX-70 ATTENTION The function blocks are designed so that a function block output can be assigned directly to the input of another function block. This enables you always to have an overview of which value is transferred. If different data formats are used, such as if the first function block uses 32 bits and an 8-bit or 16-bit format is used for further processing, sign value errors or value errors may occur when transferring from one function block to another one.

Pico-Link and Point-to-Point Serial Connections IMPORTANT 6-5 Every station with a circuit diagram has read access to the physical station inputs and outputs of other stations and can process them locally. Example 1 Station 1 is to read the input I1 of station 2 and write to output Q1 of station 2. Station 2 does not have a circuit diagram. Figure 6.
6-6 Pico-Link and Point-to-Point Serial Connections Functions of the Stations in the Network The stations on the Pico-Link can have two different functions: • Intelligent stations with their own programs (stations 1 to 8) • Input/output devices (REMOTE IO) without their own program (stations 2 to 8) IMPORTANT Station 1 must always have a circuit diagram.
Pico-Link and Point-to-Point Serial Connections Configuring the Pico-Link 6-7 The Pico-Link can be configured so that it can be optimized for your application. Station Number The station number is identified as the Pico-Link ID in the device. The station number can be set on devices with a display using the buttons on the Pico GFX-70. IMPORTANT All the Pico-Link settings are best carried out on station 1. The entire network can be configured via station 1.
6-8 Pico-Link and Point-to-Point Serial Connections Pause Time, Changing the Write Repetition Rate Manually Every Pico-Link segment automatically determines the number of active stations, the baud rate, and the total number of bytes which are transmitted. The minimum pause time which a device requires is automatically determined using this data to ensure that all devices can send their messages. If a pause time is to be increased, the value of the BUSDELAY: must be set greater than zero.
Pico-Link and Point-to-Point Serial Connections 6-9 Send Each Change on the Inputs/Outputs (SEND IO) The SEND IO function should be used if you wish to send any change in input or output status immediately to all other network stations. SEND IO should be activated if intelligent stations have read access to the inputs and outputs of other stations (2I 02, 8Q 01, etc.). ✓ SEND IO This means that the quantity of messages on the network can increase significantly.
6-10 Pico-Link and Point-to-Point Serial Connections The following is of utmost importance during commissioning: ATTENTION If several engineers are commissioning a machine or system involving several spatially separated elements via the Pico-Link, it must be ensured that REMOTE RUN is not activated. Otherwise unwanted machine or system starts may occur during commissioning. The associated events depend on the machines or systems involved.
Pico-Link and Point-to-Point Serial Connections 6-11 The standard settings for the input and output devices are: SEND IO ✓ REMOTE RUN ✓ REMOTE IO ✓ Station number (Pico-Link ID) and baud rate can be specified via station 1. Station Message Types The Pico-Link network recognizes various message types. They are: • Output data of station 1 (Q., S.) which is sent to stations without programs. • Network outputs and inputs sent and received between stations with programs (*SN, *RN).
6-12 Pico-Link and Point-to-Point Serial Connections Reading and sending the network data from the CPU The network CPU of the station reads every message on the network. If the message is relevant to the station, it is accepted into a message memory. If the content of a send message changes, it is sent. Transmission only occurs when there is no message on the network. The Pico-Link is configured so that every station can send its messages.
Pico-Link and Point-to-Point Serial Connections 6-13 Evaluation occurs at the following intervals: Baud rate Stations must send a “sign of life” every ... Stations recognize the absence of a “sign of life” signal after [KB] [ms] [ms] 1000 60 180 500 60 180 250 120 360 125 240 720 50 600 1800 20 1500 4500 10 3000 9000 If the absence of a “sign of life” is detected, the respective diagnostics contact is set to 1.
6-14 Pico-Link and Point-to-Point Serial Connections IMPORTANT ATTENTION If a station does not send a “sign of life” signal (station not available, Pico-Link interrupted), the respective diagnostics contact ID is activated. If the states of the inputs, outputs or data are required by a station without fail, the respective diagnostics contact should be evaluated and the information applied in accordance with its respective application.
Pico-Link and Point-to-Point Serial Connections 6-15 Network Transmission Security The Pico-Link is a CAN-based network. CAN is used in cars and commercial vehicles in all areas. The same fault recognition capability with data transfer applies as with CAN. A BOSCH study relating to undiscovered and corrupt messages determined the following: The probability of non-discovery of a corrupted message (residual error probability) is: < 10-10 message error rate.
6-16 Pico-Link and Point-to-Point Serial Connections Introduction to the Serial Interface The Serial Interface is a point-to-point connection using the serial interface. This interface connection allows the reading of input/output states as well as the reading and writing of marker ranges. This data can be used for set point entry or for display functions. The stations of the Serial Interface have different functions. The active station controls the entire interface connection.

7-14 Pico GFX-70 Settings Activating Input Delay (debounce) Input signals can be evaluated by Pico GFX-70 with a debounce delay. This enables, for example, the trouble-free evaluation of switches and push button actuators subject to contact bounce. In many applications, however, very short input signals have to be monitored. In this case, the debounce function can be switched off. 1. Press DEL and ALT to call up the System menu. 2. Select the SYSTEM menu.
Pico GFX-70 Settings IMPORTANT Activating and Deactivating the P Buttons 7-15 How Pico GFX-70 input and output signals are processed internally is explained in Delay Times for Inputs and Outputs on page 8-5. Even though the cursor buttons (P buttons) have been set as push button actuator inputs in the circuit diagram, this function is not activated automatically. This prevents any unauthorized use of the cursor buttons. The P buttons can be activated in the System menu.

7-22 Pico GFX-70 Settings Retention It is a requirement of system and machine controllers for operating states or actual values to have retentive settings. What this means is that the values will be retained safely even after the supply voltage to a machine or system has been switched off and are also retained until the next time the actual value is overwritten.
Pico GFX-70 Settings 7-23 Requirements To make data retentive, the relevant markers and function blocks must have been declared as retentive. ATTENTION The retentive data is saved every time the power supply is switched off, and read every time the device is switched on. The data integrity of the memory is guaranteed for 1010 read/write cycles. Setting Retentive Behavior Requirement: Pico GFX-70 must be in STOP mode. 1. Switch to the System menu.
7-24 Pico GFX-70 Settings 9. Press ESC to exit the input for the retentive ranges. CI 00 -> CI 00 ▲ DB 00 -> DB 00 T 00 -> T 00 ▼ Up to six different ranges can be selected. B:200 IMPORTANT MB 01 -> MB 04 C 12 -> C 16 The display on the lower right B:200 indicates the number of free bytes. Example: MB 01 to MB 04, C 12 to C 16, DB 01 to DB 16, T 26 to T 32 should be retentive. CH 00 -> CH 00 CI 00 -> CI 00 DB 01 -> DB 16 T 26 -> T 124 bytes have been assigned to the retentive data range.
Pico GFX-70 Settings 7-25 Changing the Operating Mode or the Circuit Diagram When the operating mode is changed or the Pico GFX-70 circuit diagram is modified, the retentive data is normally saved together with their actual values. The actual values of relays no longer being used are also retained. Changing the Operating Mode If you change from RUN to STOP and then back to RUN, the actual values of the retentive data will be retained.

Chapter 8 Inside Pico GFX-70 Pico GFX-70 Program Cycle In conventional control systems, a relay or contactor control processes all the circuit connections in parallel. The speed with which a contactor switches is thus dependent on the components used, and ranges from 15 to 40 ms for relay pick-up and drop-out.
8-2 Inside Pico GFX-70 Evaluating Function Blocks • process the function blocks which are used: the output data of a function block is updated immediately after processing. Pico GFX-70 processes the function blocks according to the function block list (see Calling the Function Blocks via the FUNCTION RELAYS Menu on page 4-29) from top to bottom. You can sort the function block list with PicoSoft Pro. You can then, for example, use the results consecutively.
Inside Pico GFX-70 8-3 Example: screen size 250 bytes: The loading time for the screen is: 250 x 80 µs = 20 ms IMPORTANT If you require the GFX to have a small cycle time: use several small screens so that the loading time is not too long during a screen change. Only display necessary information in the screens concerned. The loading of screen data and screen changes can be implemented in any segment of the program cycle.
8-4 Inside Pico GFX-70 I 01----Q 04--| | |------| --------I 03-L: 8 C:2 B:7688 Example: Do not Wire Backward This example is shown in Creating and Modifying Connections on page 4-21. It was used here to illustrate how NOT to do it. In the third circuit connection, Pico GFX-70 finds a connection to the second circuit connection in which the first contact field is empty. The output relay is not switched. When wiring more than four contacts in series, use one of the marker relays. Figure 8.
Inside Pico GFX-70 8-5 Only use as much retentive data as is actually required. IMPORTANT The screen with the largest memory requirement reduces the memory available for the program. Several smaller screens allow more space for the program. Use as small pictures as possible with 1 bit grayscale. The pictures should normally be 32 x 32 pixels in size to fully utilize the optimum brilliance of the display.
8-6 Inside Pico GFX-70 The same debounce delay (C) applies when the signal drops out from 1 to 0. If you use high-speed counter function blocks, the debounce delay time for the inputs is 0.025 ms. Otherwise it is not possible to count high-speed signals. IMPORTANT If the debounce is switched off, Pico GFX-70 responds to an input signal after just 0.25 ms. Figure 8.
Inside Pico GFX-70 Monitoring of Short-Circuit and Overload with 1760-IB12XOB8 8-7 Depending on the type of expansion module in use, it is possible to use the internal inputs I16, R15 and R16 to monitor for short-circuits or overloads on an output. • Pico GFX-70: – I16: Group fault signal for outputs Q1 to Q4. • 1760-IB12XOB8: – R16: Group fault signal for outputs S1 to S4. – R16: Group fault signal for outputs S5 to S8.
8-8 Inside Pico GFX-70 The above circuit operates as described in example 1. The signal light is triggered at Q4 for additional overload monitoring. If Q4 has an overload, it would “pulse”. Example 3: Automatic Reset of Error Signal Figure 8.
Inside Pico GFX-70 8-9 Transfer Behavior The input and output data of the expansion units is transferred serially in both directions. Take into account the modified reaction times of the inputs and outputs of the expansion units. Input and Output Reaction Times of Expansion Units The debounce setting has no effect on the expansion unit.
8-10 Inside Pico GFX-70 Example Power can be applied to the expansion unit later than the basic unit. This means that the basic unit is switched to RUN when the expansion unit is absent. The following Pico GFX-70 circuit diagram detects if the expansion unit is functional or not functional. Figure 8.
Inside Pico GFX-70 8-11 Figure 8.9 Remove cover and plug-in To close the slot again, push the cover back onto the slot. Memory Module The module is available as accessory 1760-MM3 for Pico GFX-70. Circuit diagrams containing all the relevant data can be transferred from the 1760-MM3 memory module to Pico GFX-70. Each memory module can hold one GFX program. Information stored on the memory module is “non-volatile” and thus you can use the memory module to archive, transfer and copy your circuit diagram.
8-12 Inside Pico GFX-70 On the memory module you can save: • the program • all the visualization data of the screens • all parameter settings of the circuit diagram – the system settings – debounce setting – P buttons – password – retention on/off and range – Pico-Link configuration – setting for automatic startup in Terminal mode – Serial Interface settings – DST settings – Memory module mode Insert the memory module in the open interface slot. Figure 8.
Inside Pico GFX-70 8-13 Loading or Saving Circuit Diagrams You can only transfer circuit diagrams in STOP mode. The Pico GFX-70 versions without a keypad and display automatically transfer the circuit diagram from the inserted memory module to the GFX processor when the power supply is switched on. If the memory module contains an invalid circuit diagram, Pico GFX-70 will keep the circuit diagram still present on the device.
8-14 Inside Pico GFX-70 Loading a Circuit Diagram from the Memory Module 1. Select the CARD-> DEVICE menu option. DEVICE-CARD CARD-DEVICE DELETE CARD 2. Press OK to confirm the prompt if you want to delete the Pico GFX-70 memory and replace it with the memory module content. 3. Press ESC to cancel. INVALID PROG If there are transmission problems, Pico GFX-70 will display the INVALID PROG message.
Inside Pico GFX-70 8-15 PicoSoft Pro PicoSoft Pro is a PC program for creating, testing and managing circuit diagrams for Pico GFX-70. IMPORTANT IMPORTANT You should only transfer data between the PC and Pico GFX-70 using the Pico GFX-70 PC interface cable, which is available as accessory 1760-CBL-PC02. (The cable is also available as part of the Software/cable kit, catalog number 1760-PICOPRO-PC02.) Pico GFX-70 cannot exchange data with the PC while the circuit diagram display is on screen.
