The following applies to function blocks:
h
The most recent actual values are cleared if the power
supply is switched off or if easy800 is switched to STOP
mode. Exception: Retentive data keeps its state
(a Section “Retention”, Page 283).
The most recent actual values are transferred to the
operands every cycle. The data function block is an
exception.
h
Attention!
The following applies to RUN mode: easy800 processes
the function block after a pass through the circuit diagram.
The last state of the coils is used for this.

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.
