2) Timing chart (while M8027 is ON)

*1.
Cleared when the PR mode is changed from RUN to STOP.
Cautions
1. Command input and instruction operation
While the command input is ON: Even if the command input is continuously ON or if the pulse operation type
instruction is used, execution is completed after a series of outputs. M8029
turns ON only while M8027 is ON.
While the command input is OFF: All outputs are OFF.
2. Relationship with the scan time (operation cycle)
This instruction is executed in synchronization with the scan time.
If the scan time is short, the constant scan mode can be used. If the scan mode is too long, the timer interrupt
function can be used.
3. Output type of the PLC
Use a transistor output type PLC.
4. When "00H (NUL code)" is contained in the data (while M8027 is ON)
The instruction is executed completely, and the data after "00H" is not output.
M8029 remains ON during one operation cycle.
