Ϩʳ Once the
S2
-set pulse waves are transmitted, the Y0 output will be
completed and M1029 =ON, and the Y1 output will be cmpleted and
M1030 =ON.
Ϩʳ Number of times of the command usage
For commands PLSY (DPLSY), PWM and PLSR (DPLSR), they could
only be used once for each output.

M1042: Start pulse S2: Auto mode initial step point
M1047: STL Monitoring enable
When using the IST command, S10 to S19 are for retruning to the original
point. These step points can not be used in other step ladder programs.
