Object value "Logical connection 1"
after bus voltage recovery
Options:
Do not write
Write with "0"
Write with "1"
This parameter defines the value assigned to the
Logical connection 1
group object on bus voltage
recovery.
•
Do not write
: After bus voltage recovery, the
Switch
group object retains the value 0. The value
remains the same until the group object is modified by the bus. The contact position is only re-
evaluated and set at this point. The correct status of the contact position is displayed via the
Status
Switch
group object independently of the value of the
Switch
group object. However, a precondition is
that no manual switching operations have occurred on outputs A, C, E, G, I or K.
Note
The values of group objects
Logical connection 1/2
are stored on bus voltage failure. The values
are set again after bus voltage recovery
If values are not assigned for these group objects
Logical Connection 1/2
they will be
deactivated.
On reset via the bus, the values of group objects
Logical Connection 1/2
remain unchanged.
A further parameter appears if GATE is selected in the
Function of logical connection
parameter:
GATE disabled if object value
"Logical connection 1" is
Options:
1
0
This parameter defines the value at which group object
Logical Connection 1
disables the GATE.
While it is disabled, telegrams received on the
Switch
group object are ignored. As long as GATE is
activated, the value that last sent to the input of the gate remains on the output. After a gate is disabled,
the value that was on the output beforehand remains on the output of the gate.
After the gate is enabled, this value will be retained until a new value is received.
For further information see: Function diagram, p. 126
GATE is disabled after bus voltage failure and remains deactivated after bus voltage recovery.
Logical connection 2 active
This has the same parametrization options as
Logical Connection 1 active
