• The function block retains the value of the last valid
operation.
Inputs
The function block inputs
>SH, >SL and >SV can have the
following operands:
•Constants
• Markers MD, MW, MB
• Analog inputs IA01 to IA04
– IA01: terminal I7
– IA02: terminal I8
– IA03: terminal I11
– IA04: terminal I12
• Analog output QA01
• Actual value
… QV> of another function block
Actual value ..QV>
The actual value
…QV> can be assigned the following
operands:
• Markers MD, MW, MB
• Analog output QA01
h
Counter CI counts every rising edge on the counter input.
If the value range is exceeded, the switching contact CI
..CY switches to status 1 for one cycle per rising edge
