Memory requirement of the counter relay
The counter relay function block requires 52 bytes of memory
plus 4 bytes per constant on the function block inputs.
Retention
Counter relays can be operated with retentive actual values.
The number of retentive counter relays can be selected in the
SYSTEM r 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 easy is started in RUN mode, the counter relay operates
with the retentively saved actual value.
