How to Connect opc server?

I have Analyzer which connects to a computer with cat5 cables . This Computer reads the data through a software called ComVisioner .ComVisioner has two Modes, one is Server Mode and Other is Client Mode A Server software acts as the engine in the system, providing one or more clients with information.

Server version is installed on a single computer . Once Server version is installed it collects data, performs calculations, produce reports and so on.

The ComVisioner client runs in the same computer as the server. Other clients can access the same single server through a network, providing that the software license allows more than one client at the same time

so there is Two client computers who access the as mentioned above .this all connection is done by Network cables . This part is fine

As License of Client is very expensive our company wants to add a OPC software so that more user can acquire data .As i have no knowledge on Opc part please suggest me How can i do it ?. what sort of software should i use ?. Can i install this software different pc with is connected in same network

There is also one more software installed in that computer which pushes the data as Modbus protocol

In case you are not aware Stackoverflow focuses on computer programming. To be able to answer your question we would need much more information. Nothing much comes up searching for the software you mention, I could not even find anything referring to Modbus or OPC. Being a commercial software it's not even sure you as the owner of the software have that information or are legally able to share it (as it is written, your question seems to imply you want to find a way to bypass the licensing). Conclusion: rework your question if you don't want to see it downvoted or removed. - Marcos G.
i am not talking about by pass licensing , we want to implement a new system of opc software ( looking for best suggestion) which can read data from Analyzer . if you want any data or documents i can provide you - Anoop Vijayan
If your software is able to read from a Modbus TCP slave I think that would be the easiest, if you can add info on that or what kind of OPC it implements I can try to comment, otherwise, I wouldn't know where to start, your question is too broad as it is. - Marcos G.
my software does not read modbus tcp , but my software can push data as modbus rtu . as i research online i find anybus converter with convert modbus rtu to modbus tcp. Then we will use kepware (opc software ) to see data is that ok or i need some thing else - Anoop Vijayan
I see. You can use a Modbus RTU to TCP converter or use a serial port directly to read Modbus RTU (you might need an RS485 adaptor though). Once you have Modbus data you can very easily set up a Modbus client or server on your computer with pymodbus, libmodbus, or many more options. If you have kepware licenses you can read Modbus RTU and probably TCP too, see here. There is no need of OPC. - Marcos G.

First, you need to make sure that the ComVisioner can give OPC data. (work like opc server). This should be indicated in the documentation.

Download the free OPC client, and make sure you can read the data (for example you can use, matrikon opc explorer or kepware quick client (I like it more, it goes together with KepServerEx, to download them you need to register)

If you can connect and see the data, then there will be no problems with access to the data. Next you need to find a solution for which Opc client suits you. Probably some SCADA system, but some good SCADA also cost a lot, and require a lot of development time.

I don't recommend you try to use modbus if there is opc. If you will use modbus you will have many problem with addressing and value format.

ps We had a problem with expensive licenses. As a result, we solved the problem by give access for programm for clients via RDP (remote desktop connection)
