[4] Setting the M code output function
The following shows the settings to use the "M code output function".
(1) Set the M code No. in the positioning data "[Da.10] M code/Condition data
No./Number of LOOP to LEND repetitions".
(2) Set the timing to output the M code ON signal.
Set the required value in the following parameter, and write it to the Simple
Motion module.
The set details are validated at the rising edge (OFF
ON) of the PLC READY
signal [Y0].

: Refer to Section 5.6 "List of monitor data" for information on the storage details.
The following shows a sequence program example for reading the "[Md.25] Valid
M code" to the PLC CPU data register (D110). (The read value is used to
command the sub work.)
Read M codes not as "rising edge commands", but as "ON execution
commands".
