Explanation
!
Turned ON to start the timing of the step transition monitoring timer.
Turn OFF to reset the monitoring timer.
!
Turns ON at completion of sampling trace of all specified blocks, and
turns OFF at a sampling trace start.
!
Turns ON during execution of sampling trace, and turns OFF at
completion or stop.
!
Select whether to enable or disable sampling trace execution.
ON : Sampling trace execution is enabled.
OFF : Sampling trace execution is disabled.
Turn it OFF during sampling trace execution to stop trace.
!
Select the operation output at a block stop.
ON : The ON/OFF status of the coil used for the operation output of
the step executed at a block stop is retained.
OFF : All coil outputs are turned OFF. (The operation output provided
by the SET instruction is retained independently of whether
M9196 is ON or OFF.)
M9197 M9198
OFF OFF X/Y0 to 7F0 states
ON OFF X/Y800 to FF0 states
OFF ON X/Y1000 to 17F0 states
ON ON X/Y1800 to 1FF0 states
! The I/O module numbers of the fuse blown module indication (D9100
to D9107) and I/O module verify error indication (D9116 to D9123)
are changed.
!
Indication is changed at END.
!
Restores the set data stored in the CPU to enable resumption of
sampling trace/status latch when it is executed.
!
Turn M9199 ON when sampling trace/status latch is executed again.
(Data need not be written again by peripheral device.)
