Planning and application
Valves
The purging cycle restarts if it was active before the failure.
The priorities blocking, forced operation, purging and adjustment are
re-established and executed as priorities.
The priorities are defined as follows:
1. Reference movement
2. Manual operation
3. Communication object Block
4. Communication object Forced operation
5. Valve purge
6. Adjustment
7. Control values
Note
1 corresponds to the highest priority.
The value parameterised for bus voltage recovery is only carried out if
no higher priority (with the exception of manual operation/reference run)
was active before the failure. If during bus voltage recovery and an
active priority a new control value is received, it will replace the Control
value which was defined in the parameterisation.
