Hi all 

I have a problem with two counters I'm using to update the on / off values of a threshold trigger, using the arrow keys on the TD. 

It works fine in simulation but when it runs live the "CNT" parameter isn't changing, however, when you view the counter value with the glasses in online mode the counter value is updating but not the CNT parameter.

But because the CNT value in the parameter box isn't updating it's not allowing me to change the threshold trigger parameter values.

The analogue threshold trigger is looking at a pt100 sensor, the program is the start of a heating control system. 

Cheers 

Thank you very much, I just tested it online and it is actually changing the trigger points.  It just threw me because I didn't know that the parameter values are not live. 

Thanks for the help I'm sure it won't be my last question.
