Help needed to configure B&R OPC with Labview

Hi ALL,

We are using a B&R plc. The model of PLC is PP45
We have used B&R OPC 2011(by using PVI monitor 3.23) to interface some of the data deployed from the PLC to LabVIEW.
Now we want to have some more data to be read/Written from the PLC. The people who have configured the B&R plc are not available and I would like to fetch some datapoints from the PLC to OPC so that they are accessible in LabVIEW environment.

Can anyone help me regarding the steps I should follow so that I can get the new B&R PLC data into OPC.

Regards

Hi,

In this case, your colleagues may have used OPC-DA (not Opc-UA!). This is now an obsolete technology.

There were two versions of this:

1.) OPC-DA Server in the Automation Runtime (i.e. on the PLC) (‘Automation Runtime OPC Server’).

2.) indirectly via PVI, i.e. PVI connects to the PLC and provides an OPC-DA server itself (‘Windows OPC Server’).

Presumably the second was used.
