For connect and view data on uniOPC server, the client (view) need support what version of OPC da (2 or 3) ?

Is necessary programming in ladder specifics function for opc run ?

On help in visilogic have a instruction:

The socket 1 tcp Enables PC to PLC communication via UnCmDrv1.dll, including VisiLogic, Remote Access, and other Unitronics communication applications.

Socket 2 port 2025x are used for all unitrinics program and socket 3 for program like scada.

For use UniOPC what socket i need enable ?

I read the .pdf intructions for install uniopc and I got these doubts.

Thanks for yours attention
