Hello to all,
We have to reload the program on our s7-1200. The program uses PID loops. Will, after reloading the program, be neccessary to perform autotuning of the PID loops or is it enough to manually enter coefficients if neccessary(if they change to different value during upload)?
If it is neccessary to perform autotuning again, can you share the information about the procedure.
I'm not experienced with S7-1200, only have experience with S7-300 and there is no autotuning so every information will be gladly appreciated.
Thanks in advance!
