2-18 Drawing a Circuit with Pico Analog Comparator Available functions: • I7 ≥ I8, I7 ≤I8 • I7 ≥ Setpoint, I7 ≤Setpoint • I8 ≥ Setpoint, I8 ≤Setpoint The analog comparator can compare voltages from 0V to 10V (setpoints “0.0” to “10.0”). Analog signals of sensors typically fluctuate by several millivolts. For stable switching the setpoints should differ by at least 0.2V (switching hysteresis). Do not use any relay with output energize or impulse relay coil functions.
Drawing a Circuit with Pico 2-19 Text Display The Text Display is used to display eight freely definable messages on the Pico screen. Each text block displays up to 48 characters from the Pico display character set (ASCII + Pico special characters). If the Text Display is enabled, the text entered via PicoSoft is displayed. If several Text Displays are enabled, the next screen is displayed every 4 seconds. When Text Display D1 is enabled it stays displayed (fault indication).

Chapter 3 Pico Interface Socket The Pico interface socket, which is beneath a protective cap, accepts the optional Pico memory module, or connects Pico to a PC using the optional PC interface cable and the PicoSoft software. This allows you to copy the circuit diagrams to and from the PC and/or memory module. Memory Module Memory modules are available as an optional accessory. Each memory module can store a single Pico circuit diagram.
3-2 Pico Interface Socket ATTENTION ELECTRICAL SHOCK HAZARD The memory module and PC-cable socket are at the potential of L2. There is a danger of electric shock if L2 is not grounded. Do not make contact with electrical components under the socket cover. Load or Store the Circuit Diagram You can only transfer the program from Pico to the memory module or vice versa in the STOP mode. DEVICE - CARD: Transfer circuit diagram and parameter settings from Pico to the memory module.
Pico Interface Socket 3-3 PicoSoft PicoSoft is an optional PC program that creates, stores, and manages Pico circuit diagrams. It transfers the circuit diagrams from the PC to Pico or vice versa using a special PC interface cable. ATTENTION The PC interface cable is catalog number 1760-CBL-PM02 and is available as an accessory item. Only use the Pico interface cable. Do not attempt to make your own cable as this can cause damage to the unit or present a shock hazard.
