Wiring with the display system1501SVC 440 795 M1100Function blocks The function blocks are used to simulate some of the devicesused in conventional open-loop and closed-loop controlsystems. The display system provides the following functionblocks:• Analog value comparator/threshold value switch(only with display system 24 V DC versions)• Arithmetic,– addition, subtraction, multiplication, division• Compare data blocks• Transfer data blocks• Boolean operation• Counter,– up/down counters with upper and lower limit value,– preset,– Frequency counter,– High-speed counters,– Incremental counter• Comparator• Text, output freely editable texts, enter values• Data function block• PID controller• Smoothing filters• Value scaling• Pulse width modulator• Read (GET) data from the CL-NET• Time switches,– Weekday/Time,– year, month, day (date),• Numerical converter• Master reset• Operating hours counter• Write (PUT) data to the CL-NET• Synchronisation of date and time via the CL-NET
