Status definition
A general rule for the acknowledgment status is that the state information 1 to 7 leads to the termination of the
command. If FC 8 receives one of the statuses, the "Interface active bit" of the interface specified in FC 8 is reset
to "0" (see also interface lists DB 71 to DB 73), thus completing the operation. The response if different in the
case of status information 103 to 105. When the FC 8 receives one of these items of status information, the
"Interface active bit" of this interface remains at "1". Further processing is required by the user program in the
PLC (e.g. continuation of magazine positioning). This item of status information is generally used to transfer
changes in position of one or both tools while the operation is still in progress.
