Real time debugging on TM172 target

[otrotabi]

What happens if breakpoints are set on a real target (not on simulation)? Does the PLC freeze, stopping all control or it only allows us to use the debugger while timed and background tasks are still run?

Hello,

both Timed and Background tasks are paused in case of breakpoint.

You can use trigger if you want to debug a variable on a specific point of the code without stopping it.

Thanks. I am not familiar with triggers actually; I will take a look.  I want to check if a Boolean variable set at HMI which is almost inmediately reset at PLC after some action actually changes it´s state. Is a trigger the right way to check that?

I would suggest for this use case is the oscilloscope the best tool
