Dear Kaare_t
Hi. first thanks to you replying.we have Q12PRH which are connected to 5 R I/Os by modbus TCP/IP. we have 9 loops in our process .I've red some manuals about the pid and thought i can follow instructions step by step and used PID but now it didn't work.I can't change the parameters(P,I,D,TS,SV)
I appreciate if you help me
best regard
