  1. Tuning PID - how to do it properly

    Michael, Many many thanks, you helped me a lot. After playing with PID yesterday I understand a lot more. 
  2. I need some advice how to tune PID properly. The PID is only PI type (two mode) and its overshooting frequently. Assuming I need to tune P with starting incrementing by very small steps till PID oscillates.  Once the P is established then will be tuning I , again with small increments till PV follows SP.  So this is my assumption below but would like someone to comment on it as I haven’t had to do it before , been learning PLC for 4 months now.  Do I need to start a machine and then start tuning PID or can this be done in more friendly way , offline ?
