7.2.1.7. Embedded PLC execution time​

 

When using the embedded PLC, you can adjust the PLC execution time within the controller. The controller executes the PLC ladder program every 20ms internally and you can set the level to assign PLC execution.

The longer this time is set, the shorter the scan time of the PLC program will be. But if set to high, the CPU execution time will be insufficient to cause “E0047 Motion processing time exceed” error or “E0186~E0189 1st/2nd/3rd/4th DSP detected main watchdog” error.
