Function blocks The function blocks are used to simulate some of the devices
used in conventional open-loop and closed-loop control
systems. The display system provides the following function
blocks:
• 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
