PID help

[alexandru_cazan]

Hi. I need some help in configurating a PID to work in a CP1L. I tried all the possible combinations for the control words (proportional band, integral time, etc.) either in BCD or Binary and I still cannot make it to output something. Thank you for your time

Post your code. With this information we can't do much. Two important pointers: - Set control words in binary (HEX) - The control word parameters are obtained when the execution condition of the instruction turns from OFF to ON, and the Error Flag will turn ON if the settings are outside of the permissible range.

try this example with PIDAT (PID with autotuning) just execute autotuning (W0.00) and the values for the P, I and D parameters will be automatically calculated. Example_PIDAT.cxp
