Memory requirement of the high-speed counter
The high-speed counter function block requires 52 bytes of
memory plus 4 bytes per constant on the function block
inputs.
Retention
High-speed counter relays can be operated with retentive
actual values. The number of retentive counter relays can be
selected in the SYSTEM r RETENTION menu.
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.
