Adjustable shift register

[Igi]

Hello I am beginner of Unitronics PLC. I have V350 series,R34. Is here a demo or an example this type of application? First problem which I have to solve is how to set value into timer by writing value via HMI. Could you help me?

Thanks, but I can not find any similar examples.

My first problem was resolved. Now I am thinking how to switch outputs periodically..

I've attached a program showing how to toggle an output using two timers.

Thanks. I have done my "project". But I have 1 problem with  toggling an outputs which I have been solving for 1 week but I still can not find the solution. I can not use your solution because I use the timer which time settings value is from variable in HMI. It is not a constant in the program. Why does my oscillator count twice faster?

Hi,

Why do you need Timer coil after INC block? Delete it and test.

Check if you have others coils of the same Timer.

If you activate Timer coil N times per scan - in will count N times fastest.

Thanks, but I need to create an oscillator. If I do not use the timer coil it will not oscillate.. I need to increment the counter in defined time(which can be changed via HMI). Is there any other easy way to do it?
