Output
Actual value output C..QV supplies the current actual value as an integer.
You can assign the following operands to output
…
QV:
•
Analog output QA01.
•
Markers MD, MW, MB.
Retention
Counter relays can be operated with retentive actual values. The number of
retentive counter relays can be selected in the SYSTEM RETENTION
menu. The retentive actual value requires 4 bytes of memory.
If a counter relay is retentive, the actual value is retained when the operating
mode changes from RUN to STOP as well as when the power supply is
switched off. If easy800 is started in RUN operating mode, the counter relay
operates with the retentively saved actual value.
