Hello ixo65,

I have a threshold trigger that is not activating.  The mathematic instruction block is enabled.  I also noticed that the Aq value at the mathematic instruction block is showing 0.  But when online and I click the goggles the value is there. 

It is set to trigger at 36 meters for my application, but it isn't working.  I've tried different values changing blocks but I'm obviously missing something simple.

I have used this process a lot and I have never struck this problem.  Same software, V8.4.0.  Logo modules both the same 6ED1052-1HB08-0BA2.

Any help appreciated.

Thanks,
James.

Your problem is that the input value to the analog threshold trigger B011 changes in steps of 14.
This value comes from the math instruction B006. There, you multiply the value of counter B010 by a factor of 14. If counter B010 reaches the value 257, the value 3598 is passed to B011 (257 x 14 = 3598). This value is below the OFF parameter of B011.

If the counter value of B010 is then incremented by 1, the analog threshold trigger B011 receives the value 3612 (258 x 14 = 3612). This value is higher than the OFF parameter.
