Freelance OPC_FB-LIB SCADA Text


I have a user Function Block (P-FB ) in Freelance where I use some PARA_VIS texts to be shown on the faceplate.

I want to monitor one part of a plant that use this functions block (among others), on other diferent "Freelance" system (this other freelance system has his own trend server, eng station, etc.), I was planning to sent the information using OPC-Gateway, but those text on my user function block are not sent by OPC. The first questions: Is there any way to sent by OPC a "PARA_VIS" ? The sencond one is there any method to include "PARA_VIS" on OPC_FB-LIB? By the way I am using Freelance 2016 SP1.

PARA_VIS means that information is only loaded into Freelance Operations (former DigiVis). The OPC gateway only exposes data that the controller has, nothing from the operations console. What you could do is to move the text to the controller, let it come out of your user function block as output and then declare it inside your faceplate appropriately.

Why not copy the user FB to this other system and use it there as is?

thank you I will test it and come back to you if there is any issue. I don't copy it because this is a common area of the two freelance (handle by one controller) that should be monitor on both control rooms.
