Behaviour when value range is exceeded
• The function block sets the switching contact CI…CY to
status 1.
• 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
The counter CH counts on every rising edge at the counter
input. If the value range is exceeded, the switching contact
C ..CY switches to status 1 for one cycle per rising edge
detected.
h
The actual value is only erased in RUN mode with a
selective reset signal.
