Figure 407: Interlocking module on bay level
Bays communicate via the station bus and can convey information regarding the following:
•
Ungrounded busbars
•
Busbars connected together
•
Other bays connected to a busbar
•
Received data from other bays is valid
Figure
illustrates the data exchange principle.

Figure 408: Data exchange between interlocking modules
When invalid data such as intermediate position, loss of a control IED, or input board error are
used as conditions for the interlocking condition in a bay, a release for execution of the function
will not be given.
On the local HMI an override function exists, which can be used to bypass the interlocking function
in cases where not all the data required for the condition is valid.
