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 this computer . Server version will collects data, performs calculations, produce reports a from analyzer

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, they 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 ?

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

if you any documents regarding above
