Greetings friends,

I'm using a CPU 1214C (6ES7 214-1AG31-0XB0) to test some capacitor jigs. I have the main testing function in a FB, which has three timers. However, when the main program activates the first instance of the FB to test the jig, the timers aren't working, so I can't transition between states.

I already tried switching the timer to a different network, but it doesn't work either.

Please help, I no longer know what to do, I've been reading about this for hours.

What is TON instance's IN parameter start value?

So your FB1 has multiple instances, right? 

Then calling inside of the FB any other FB having its separate DB will work erratically.

Define timers in an interface of the FB 1.

What is TON instance's IN parameter start value?

 IN is Boolean. Everything on the timer's Data Block is the same as on the picture you attached.

Yes jacek, FB1 is called 35 times on the main program. So if I create a function block only with the timer, and call that function block inside FB1, it's going to work?

I will try using the timer on the main function, and the parameter Q of the timer as a boolean value that I can use on FB1. Maybe that will work, if nothing else works (although it will take a lot more of work to do it).

"If FB1 is called multiple times, the TONs inside that FB need to be stat parameters inside that FB, like Timer1 : TON_TIMER or IEC_TIMER as internal to the FB."

I'm a bit confused, how do you do that inside the FB?
