AND logic operation; Value of the logic object after bus voltage recovery:
1; Relay: make contact
The logic object is preassigned the value “1” after a RESET.
Switching can therefore be carried out as usual via the
switch object. The closing lock-out is only active after the
receipt of a “0” telegram via the logic object.
AND logic operation; Value of the logic object after bus voltage recovery:
0; Relay: make contact
The parameter setting causes the “Logic object” to be set to
the value “0”. After a RESET, the actuator will not switch the
output in the “make contact” mode nor with these settings,
until a “1” telegram has been received at the “Logic object”.

- Logic operations
With this functionality, the “Switch object” can be logically
linked with the “Logic object”. An AND or OR logic operation
can be set. A parameter defines which value is preassigned
to the logic object after bus voltage recovery.
For example, if the OR logic object is preset to “1” after bus
voltage recovery, the output remains switched on until a
“0” telegram has been received at the “Logic object”. Any
parameterised reaction after bus voltage recovery is only
adopted once the logic operation has finished.
The logic function has a high priority. The actuator will thus
always be set according to the logic result of the higher pri-
ority function and not the status of functions with a lower
priority.
AND logic operation
If the “Logic object” is set to “1”, switching can be carried
out as usual via the address of the “Switch object”. Any set
delay periods and staircase timers are followed. Switching
off via the “Logic object” takes place immediately (object
with higher priority). An OFF delay is no longer carried out.
If the “Logic object” is set to “1” again by a telegram, the
output is also switched without a delay when the ON delay
is activated.
Example:
A closing lock-out can be implemented with an AND logic
operation. This means that it is not possible to switch on
the output via the “Switch object” while the value of the
“Logic object” remains set to “0”. If the value of the “Switch
object” is set to “1”, the output is switched on automatically
following a change in the value of the logic object from “0”
to “1” (output is set).
