Hi, I’m after a bit of advice on how to setup PLC watchdog alarm in FactoryTalk ME.
I would like to monitor a register and alarm on if it doesn’t change over a time period.
My intention was to run a macro every 1sec, that moves the PLC register to an internal register, at increments Counter (internal register). When the counter reaches 5, compare the values if they are the same set alarm.
This should be easy but can’t see how to do it.
Any advice would be great.
Thanks
