I want to use a goto Loop in a pH subroutine (RSLogix).
Issue #1: From reading the posts here I have one immediate concern, which is that the watchdog timer S2:3/H will interfere with my loop. I anticipate that the loop needs to be active for ~10 minutes and the watchdog timer defaults to 10ms.
(10 min / 10ms) = 60000!
I rather doubt that i can increase the watchdog timer value enough.
Issue #2: I went into LogixPro Simulator to see what the consequence might be to an infinite loop. To my surprise, it was necessary to use Windows Task Manager to recover. If i manage to put a ML-1100 into such a loop, and since it reboots by running whatever program is loaded, how might I recover. I would like to know this answer before i do the loop!
