DCOM we can connected to ABBafwOPCDASurrogate via Matrikon OPC we can also add
item but problem that value of tag show bad Communication below image for more detail
any one can help please
1. Verify that subscription is possible locally in the node where the surrogate is invoked. The advdsopcclient.exe tool shipped with 800xA can be used for this test. Verify data quality.
2. If remote connection (implying DCOM) is required in combination with asynchronous subscription method, quite some account and DCOM settings are required.
Please read attached document.
