devices.
After the selection of an apparatus and before the execution, the switch controller performs
the following checks and actions:
•
A request initiates to reserve other bays to prevent simultaneous operation.
•
Actual position inputs for interlocking information are read and evaluated if the operation
is permitted.
•
The synchrocheck/synchronizing conditions are read and checked, and performs
operation upon positive response.
•
The blocking conditions are evaluated
•
The position indications are evaluated according to given command and its requested
direction (open or closed).
The command sequence is supervised regarding the time between:
•
Select and execute.
•
Select and until the reservation is granted.
•
Execute and the final end position of the apparatus.
•
