Open Pol-65 opened 3 years ago

Pol-65 commented 3 years ago

Good time of day! In my telemetry project i use OPCDA-server of SOFREL_Lacroix.

OPCDA-server: IP:192.168.88.251 User: OPC Screenshot below. ClsID

Client: IP:192.168.88.253 User: Admin Screenshot below. node-red-contrib-opcda-client

Error - "Clsid is not found."

Please help!!!!

For the first insight it might be because of the DCOM Setting of OPC Server. You can find the DCOM configuration settings below

DCOM Setting of OPC Server is absolutely correct.

Can this work on Linux to connect to a windows OPC DA server? I understand COM and DCOM use windows registry and class ids. Just curious. I tried and got the class id issue.

It can be connected from Linux Server. Could you please try to connect from Matrikon Explorer? If connection is successful, we can check it from our linux instances.

Good news! Can we communicate by e-mail?

Hi Emrebekar,

Thank you for your response, adding on to @AnoojKrishnanR request

The OPC-DA server running in windows can connect to Matrikon Explorer, server parameters are be like:

'Class', 'Graybox.OPC.DAWrapper' 'OPC Server', 'WINCC_OA.OPC.1' 'Protocol', 'DCOM' 'OPC Host', 'BLTSL01807' or this can be IP

could you please provide client side nodejs code snippet to connect this server,

Thank you, Regards, Ranjith
