Memory requirement of the timing relay
The time relay function block requires 48 bytes of memory
plus 4 bytes per constant on the function block input.
Retention
Timing relays can be operated with retentive actual values.
The number of retentive timing relays can be selected in the
SYSTEM r RETENTION menu.
If a timing 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 timing relay operates with
the retentively saved actual value. The state of the trigger
impulse must correspond to the function of the timing relay.
1 signal when:
•on-delayed,
• single pulse,
•flashing.
0 status for offdelayed.
Function of the timing relay function block
Timing relay, on-delayed with and without random
switching
Random switching
The contact of the timing relay switches randomly within the
setpoint value range.
