Hi Folks
I started studying the PID block and kind of expierimenting with it on my test PLC at work. In the help files I found this.
Thanks and later...Todd
I started studying the PID block and kind of expierimenting with it on my test PLC at work. In the help files I found this.
I have a Senix ultra sonic sensor connected to I:1.1 of my analog input card.{I would have included a screenshot of the logic,but we had a busy day and it was close to shift change when I did this.}I left the reset and rate at 0 and double clicked the proportional gain and started adjusting it.I tried several times and I wasn't quite sure what I should be looking for or even if I was doing this correctly. I have the sensor in a vice so it won't move. If anyone could give me some insight I would be greatful.Controller Gain Kc Type in a value. (With 5/02 controllers the valid range is 0.1 to 25.5. With the 5/03, 5/04, and 5/05 controllers the valid range = 0 to 3276.7) This is the proportional gain. Generally set this gain to one half the value needed to cause the output to oscillate when the reset and rate terms are set to zero. Note: RG bit must be set to accept values exceeding 25.5 when using 5/03, 5/04, and 5/05 processors.
Thanks and later...Todd
