Behavior 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
J
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 detected.
J
The actual value is only erased in RUN mode with a
selective reset signal.
