2) Timing chart (When M8027=ON)
Related devices
*1. Cleared when changed from RUN to STOP.
Cautions
1. Command input and operation of instruction
Command input=ON : Even in the midst of continuous ON or pulse instruction execution, when the output of
one cycle is over, the execution is terminated.
M8029 operates only when M8027=ON.
Command input=OFF:All outputs are OFF.
2. Relation with scan time (operation time)
This instruction is executed in synchronism with the scan time.
If the scan time is short, it is driven by constant scan mode, or if too long, it is driven by using the timer
interrupt mode.
3. Output of PLC
Use the transistor output for the output of the PLC.
4. If 00H (NUL) exists in the data (when M8027=ON)
The instruction execution is completed, and the remaining data is not issued.
M8029 remains ON during 1 operation cycle.
5. Some restrictions to applicable devices.
S1: The FX3U and FX3UC PLCs only are applicable.
