Logical connection 1
Output A
1 bit (EIS 1)
DPT 1.002
C, W
This communication object is enabled if in parameter window A: Function
the parameter Enable function "logic" has been selected with the option yes.
Using this communication object, the output of the first of two logic objects can be assigned.
The logical connection is defined in the parameter window A: Logic.
Initially, the switch object is then logically linked with the communication object Logical
connection 1
. The result of this is then logically linked with the communication object Logical
connection 2
.
Note
The values of the communication objects Logical connection 1/2 are stored
at bus voltage failure. The values are restored at bus voltage recovery.
If values of the communication objects Logical connection 1/2 were not
assigned, they will be deactivated.
At a reset via the bus, the values of the communication objects Logical
connection 1/2
remain unchanged.
For further information see:

Logical connection 2
Output A
1 bit (EIS 1)
DPT 1.002
C, W
See communication object 18.

Forced Positioning
Output A
1 bit (EIS 1)
DPT 1.003
C, W
This communication object is enabled if in parameter window A: Function
the parameter Enable functions "priority and safety operation" has been selected with the
option yes and the parameter Contact position if forced operation has been selected with a 1
bit object
.
If the object receives the value 1, the output is forcibly set to the parameterised switch
position, which has been set in the parameter window A: Safety.
The forced positioning of the contact should remain until forced operation is ended. This is
then the case when a 0 is received via the communication object Forced operation.
Please note that the function Security priority 1 and a bus failure have a higher priority on the
switching state, see
