Hi, The requested manual about parameter description: As the previously referenced FAQ What should you watch out for when calling and assigning parameters to the controller functions in function blocks (S)FB41, (S)FB42 and (S)FB43? says, the COM_RST needs to be on for a(one) block cycle. The easiest way to test these things, using a VAT table. Your assumption regarding to P part being proportional to the error seems right. To be exact the formula: PID_OUTV (t) = I_ITLVAL + GAIN * ER Normalized (t) , see the page 4-41 in Standard PID Control manual. Follow the notes in the FAQ and read the manual, if you any further question please come and ask! It is very interesting topic! Please keep us posted how are you getting on with issue! Cheers |
