Meaning
This flag is changed to TRUE when a ExecP-
MCR instruction (sequence) is executed. The
flag remains FALSE when execution fails.
When the sequence is completed and the
receive data is written, the flag is changed to
FALSE after all the receive data is written to
the memory used for CJ-series Unit.
This flag is changed to FALSE when the
sequence is completed (either when it is ended
by End, or when it is ended by Abort).
Note When the scan response notification
method is set for the sequence, first a
check is made to see if the received data
was written to the memory used for CJ-
series Unit before the Protocol Macro
Executing Flag is changed to FALSE.
This flag is changed to TRUE when a step
ended abnormally. It remains FALSE if the step
ends normally as a result of a retry.
TRUE: Step ended abnormally
FALSE: Step ended normally
This flag is changed to FALSE when process-
ing is ended by using the Abort Switch from the
user program. When the Abort Switch is
changed to TRUE at the end of a sequence,
the sequence may end with either End or Abort
status.
This flag is changed to TRUE while time-series
data for send and receive messages is traced
with an instruction from the CX-Protocol.
This flag is changed to TRUE when a
sequence is completed for the next process or
for an error process with an End command.
When a sequence ends normally, setting End
(Abort when the sequence ends abnormally)
enables this flag to be used to determine
whether or not the sequence execution ended
normally.
TRUE: Sequence ended
FALSE: Sequence not ended
This flag is changed to TRUE when a
sequence is ended for the next process or for
an error processing with an Abort command.
TRUE: Sequence aborted
FALSE: Sequence not aborted
