– off-delayed, also retriggerable,
– off-delayed with random switching, also retriggerable,
– on and off delayed,
– on and off delayed with random switching,
– single pulse,
– synchronous flashing,
– asynchronous flashing,
• Set cycle time
• Value limitation
The following applies to function blocks:
J
The most recent actual values are cleared if the power
supply is switched off or if EZD is switched to STOP mode.
Exception: Retentive data keeps its state (
“Retention”, Page 378).
The most recent actual values are transferred to the
operands every cycle. The data function block is an
exception.
J
Attention!
The following applies to RUN mode: EZD processes the
function block after a pass through the circuit diagram. The
last state of the coils is used for this.
J
If you want to prevent other people from modifying the
parameters, change the access enable symbol from “+” to
“–” when creating the circuit diagram and setting
parameters and protect the circuit diagram with a password.
