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

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 EZD is started in RUN mode, the counter relay operates with

the retentively saved actual value.
