Parallel OPC connection in 800xA.
I have 4 PM 573-Eth and central DCS plant.
I have to collect data from all 4 PLC to central DCS plant.
For that I have used OPC connection.
After uploading from OPC I get all variables.
But in quality of data it shows Bad ( not connected ) in 3 connection and Good quality 1 cnnection.
( I have appeded 4 PLC in single AE configurator and use Codesys OPC DA server,
In 800xA create new Generic OPC n/w and upload data )
