The Logic function is always re-calculated when a group object value is received.
Gate function example
•
The GATE connection is set to disable as soon as the communication object
Logical connection x
receives a 0.
•
The output of the logical connection is 0.
•
The communication object
Logical connection 1
receives a 0, i.e. the GATE is disabled.
•
The communication object
Switch
receives 0, 1, 0, 1. The output of the logic operation always
remains 0.
•
The
Logical connection x
group object receives a 1, i.e. the GATE is enabled if it is set in the
parameters.
•
The output of the logical connection is recalculated.
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.
Note
If telegrams are received on the
Switch
group object during the block, they will not be stored.
For this reason, the output or the event remain unchanged when the GATE is enabled.
The output switches if the GATE is enabled and a telegram is received on the
Switch
group object.
