SetReferenceValue0 command

Quick question.  In SLC or LAD where is the SetReferenceValue0 command that copies the count value from NewReferenceValue0 to CurReferenceValue0? There is a SetCountValue command for copying the actual count but no SetReferenceValue0 command.    

Or is there an other way to accomplish this?

Mr. alwaldner

Please explain proper (little more)

What do you have and what do you want exactly ?

 I have a hydraulic motor for positioning a back-gage with a rotary encoder mounted on the motor shaft.  The encoder is connected to a TM-Positioning module on the S7-1500. I have the 2 outputs of the positioning module connected to the forward and reverse valves for the positioning motor.

I can control the back-gage with commissioning in technology objects in TIA v13 by assigning the requested position values to the newReferenceValue0 and newReferenceValue1 text-boxes then clicking on the setReferenceValue0 and 1 checkboxes. It works good. My problem is making this work in my user program.

 I can assign the requested position in SLC to NewReferenceValue0 and NewReferenceValue1 without a problem. But I have no option or SetReferenceValue0 command to transfer the NewReferenceValue0 to the CurReferenceValue0 and start the positioning.  So my question is how do I invoke the SetReferenceValue0 command in SLC in my user program.

Or if there is a better way to accomplish what I'm trying to do please advise.
