Initialize pulse after run-time download (M8126)
M8126 is a special internal relay that turns on for only one scan after run-time download has completed.
This is effective when you want to reliably initialize instructions after run-time download.
Example: A user program that initializes the AVRG instruction during run-time download
Even if the status of M0 is on during run-time download, the input to the AVRG instruction turns off for only one scan time
by normally-closed M8126, and the instruction is initialized.
Example: A user program that cancels RXD instructions in standby during run-time download
The user communication receive instruction cancel flag (port 1) turns on for only one scan during run-time download and all
RXD instructions in standby are canceled.
