Hi!
I use TIA 15.2 and try to use PID_Compact.
I enabled the "Enable Manual Entry" but still I can not get access to the P, I and D parameters to set from my display.
I'm using third part HMI so I dont have som preprogramer PID control as may be there are in Simatic TP.
How can I gain control on those parameters:
P = r_Crtl_Gain
I = r_Ctrl_Ti
D = r_Ctrl_Td

you see the parameter drop down list, those are not there.

Split from TIPS for PID (FB PID_Compact).

Hi Icoto,

it seems you are using a PID_Compact V2.x.

Then you can find the PID parameters in the structure Retain.CtrlParams.

E.g. the proportional gain can be found under Retain.CtrlParams.Gain.

You can find more details in the "Static tags of PID_Compact V2" help topic under
