Transferring values
Values are also transferred using the complete acknowledgement principle with the FM 350-
1. If incorrect values are transferred, the FM 350-1 signals an operator error with the
feedback bit OT_ERR. You must then first acknowledge the operator error bit OT_ERR with
the operator error acknowledgement OT_ERR_A before you can transfer a new, correct
value.
