Behavior when using SFC types
After a batch error is displayed in the BCC, manual operation must always be initiated. The
question mark (refer to Fig, "batch errors") shows the lost connection to the CPU. In BATCH
status "BA_STATE", BIT31 (=group error) is set. Manual continuation or cancellation of the
batch is only possible if the SFC has been manually started after considering all process
requirements (manual operation) and BATCH status "BA-STATE" i.e. bit 31) has been thereby
reset.
