*_P1_PmrExecSta *_P2_PmrExecSta BOOL R Protocol Macro
Executing Flag This flag changes to
TRUE when a ExecP-

(sequence) is executed.
The flag remains FALSE
when execution fails.
When the sequence is
completed and receive

ten to I/O memory.
This flag is changed to

End, or when it is ended
by Abort).
*_P1_PmrStepErr *_P2_PmrStepErr BOOL R Step End Error This flag is changed to
TRUE when a step ended
abnormally.
It remains FALSE if the
