Hello, with S7 1214 DC/DC/DC, is it possible to have double count value with only 1 encoder connected to the CPU HSC, what I mean is to have 2 count value inside the program, 1st value is for the total turns of rotating mandrel, the second value will be for partial turns which to be set to Zero time to time but once reset to Zero it must again calculate the turns from 0.

anyone has any idea to support pls.

Hello,

I don't know, maybe simple basic solution is copy actual HSC value to other suitable same data type TAG and manipulate with it independently. I mean with some math that add only difference from previous value and actual change of HSC, as you need have reset your second. Simple copy will be then reset to actual value what isn't expected. You  can maybe copy pulse signal from source to next free HSC and use it independently. i just give to you some ideas, all depends to your exact HW cfg and what you want to have.

Thank you so much for your help, does move the signal of HSC to another free one will affect the accuracy of the first one, is that possible as view or hardware? actually, I had this idea but little bit afraid to affect the quality of first signal, also I have a concern to do it in the software if it is possible.
