Type of object "Forced operation"
Options: 1
bit
2 bit
Using the 2 bit communication object the output state is defined
directly via the object value.
The control of the output via the communication object
Switch
is
blocked as long as the output is forcibly switched ON or OFF.
The following parameters appear when
1 bit
is selected:
Contact position on forced operation
Options: ON
OFF
unchanged
•
ON:
Contact position of the output during forced operation.
•
OFF:
Contact position of the output during forced operation.
•
unchanged
: Contact position of the output during forced
operation.
The options
unchanged, ON
and
OFF
related to the 1 bit forced
operation object and determine the switching state of the output
during forced operation. The forced operation relates to the 1 bit
forced operation object of output X which is available to every output.
Contact position with end
of the forced operation
Options: ON
OFF
unchanged
calculate present contact position
This parameter determines the contact position of the relay after the
end of forced operation.
•
ON:
The output is switched ON after forced operation has ended
•
OFF:
The output is switched OFF after forced operation has
ended
•
unchanged:
The contact position is retained during forced
operation or safety priority.
The contact position only changes when a new calculated switch
value is received.
•
calculate present contact position:
After forced operation has
ended the value (switch value) is recalculated, the switch position
is recalculated and immediately initiated, i.e., the output continues
to operate normally in the background during forced operation.
