6.5.5.6 Reject management states
The states of the Station
With respect to reject management the station is always in one of the following states:
State
Description
Running Normal
All bolts are running steps in the main part of their programs. No error has occurred.
When all bolts have stopped, either because they reached a synchronization mark or that
they failed, the station decides what reject action to take by evaluating the
Fatal failure settings for all bolts with Fatal errors
First failure settings for all bolts with Repairable errors
Should the settings lead to different actions for a given bolt the “hardest” action is taken
Running Repair
Some bolts are running their repair sequence. When all bolts have stopped, either
because they reached a synchronization mark or that they failed, the station decides what
reject action to take by evaluating the following conditions for all bolts that are not yet
ready with their repair:
Fatal failure settings for all bolts with Fatal errors
Failure during repair settings for all bolts with Repairable errors
Note 1: Only the bolts that currently are running repair are affected by any Failure
during repair actions. Bolts that never entered the repair sequence, for example
due to that they had Wait or Continue as reject action, and bolts that are already
ready with the repair sequence are not involved.
Note 2: The Fatal failure action affects all bolts, that is, also the bolts not currently
Running Repair.
Should the settings lead to different actions for a given bolt the “hardest” action is taken
Repair Ready
All bolts that once started their repair sequence have finished it. In this state the station do
not execute any steps; it only evaluates the outcome of the repair in order to decide the
next action.
The station evaluates the reject settings of all bolts that started repair and was not
terminated while executing it using the
Fatal failure settings for all bolts with Fatal errors
First failure settings for all bolts with Repairable errors
The action decided is taken for all bolts that are not terminated, this means that not only
the bolts that have done repair but also all bolts that had Wait or Continue as reject action
when the station entered the Running Repair state may have new actions ordered here.
Running Terminate
One or more bolts are running their terminate action. Synchronization is maintained for
these bolts as long as the steps end OK. Should a step fail then the bolt is considered
ready with status TERMNOK (Terminated NOK) while the remaining bolts continue the
terminate sequences.
