Please also see the attached screenshots.

We have a machine with WinCC 7.5.1.5 that delivers a value to another machine via OPC.

This value is currently a speed setpoint (LinjeHastighedSp) but we would like to change it to be a measured speed  value (LinjeHastighedPv).

In the Tag Management in the WinCC server I can find the 2 values LinjeHastighedSp on DB2008,DD22 and LinjeHastighedPV on DB2008,DD2.

i would like to switch out LinjeHastighedSp with LinjeHastighedPV in the OPC link so that the receiver on the value does not need to change anything

The owner of the machine receiving the value has informed me that it is read in DB112.

I have opened OPC Scout on the server but I cannot find any DB112. I can also not find LinjeHastighedSp or LinjeHastighedPV even though I know that the value of LinjeHastighedSp IS received somehow.

How do I find DB112 and LinjeHastighedSp (and maybe LinjeHastighedPV)?

How do I exchange LinjeHastighedSp with LinjeHastighedPv in the OPC server?
