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 Pico GFX-70 is started in RUN mode, the counter relay operates with the
retentively saved actual value.
