*_P1_PmrAbtSta *_P2_PmrAbtSta BOOL R Abort Flag This flag is changed to
TRUE when processing is
ended by using the Abort
Switch from the user pro-
gram. When the Abort
Switch is turned ON at the
end of a sequence, the
sequence may end with
either End or Abort status.
*_P1_PmrTracingSta *_P2_PmrTracingSta BOOL R Tracing Flag This flag is changed to
TRUE while time series
data for send and receive
messages is traced with
an instruction from the
CX-Protocol.
*_P1_PmrSeqEndSta *_P2_PmrSeqEndSta BOOL R Sequence End
Completion
Flag This flag is changed to
TRUE when a sequence is
completed for the next
process or for an error
process with an End com-
mand.
Note When a sequence
ends normally, set-
ting End (Abort
when the sequence
ends abnormally)
enables this flag to
be used to deter-
mine whether or not
the sequence execu-
tion ended normally.
TRUE: Sequence ended
FALSE: Sequence not
ended
*_P1_PmrSeqAbtSta *_P2_PmrSeqAbtSta BOOL R Sequence
Abort Comple-
tion Flag 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
*_P1_PmrSeqWaitSta *_P2_PmrSeqWaitSta BOOL R Sequence Wait
Flag This flag is changed to
TRUE when a sequence is
waiting due to the Wait
command.
Waiting is released when
the Wait Release Switch
changes from FALSE to
TRUE in the user pro-
gram, and the sequence
will move to the next step.
