Hello,

Is it possible to set initialization value for integration when start PID Compact?

The same as "I_ITLVAL" for "CONT_C" Continous Control Block PID in Step7 (Classic) which is set after PID complete restart.

Or is it anoher way to initialization of PID Compact afer mode changes?

Regards

Marko

Can You write how to call this ? OR can You write what  are the names of these variables

Regards

Marko,

At the start of the controller I put the pid controller in manual mode with the manual value as start value for 1 cycle. The pid controller goes bumpless from manual mode to automatic mode.

in scl:

// pid on/off
// to start with offset first put in manual mode with offset, next cycle to auto
"PIDFlowOnTrig"(  in:= #PidFlowON );
IF    "PIDFlowOnTrig".Q  THEN "PIDFlow".sRet.i_Mode := "PidManual";  "PIDFlow".ManualValue := 70.0; // start offset
ELSIF "PIDFlowOnTrig".QN THEN "PIDFlow".sRet.i_Mode := "PidInactive";
END_IF;

"PIDFlow"();

// enable pid ctl from manual (after pid fb call, need 1 cycle in manual mode)
IF "PIDFlow".sRet.i_Mode = "PidManual" & #PidFlowON THEN "PIDFlow".sRet.i_Mode := "PidAuto"; END_IF;

Thanks for help. 

This was what I was looking for.

Regards

Marko
