BATCH interface blocks
2.2 IEOP
Rules for setting the status bits
● Static states are of highest importance in BATCH. The transition states are optional. The
● Only one static state and one transition state may be active simultaneously.
allowed: HELD on its own
allowed: ABORTING on its own
allowed: HELD and ABORTING (useful in order to be able to detect the original state)
not allowed: HELD and ABORTED
not allowed: HOLDING and ABORTING
Note
Exception: The READY state may be set additive at another static state if the IREADY input
is used.
● A group error (bit 31) may be set in addition to any other state.
● The corresponding USTAT_L bit does not have to be set for entries in the "set if" column.
Batch messages
The block uses the associated values as follows:
Associated value 1 = batch name
Associated value 2 = step number
Associated value 3 = batch ID

RUNNING state may be activated directly after the IDLE state, for example.
