Can you start towards opc-UA? With OPC-DA's dependence upon Microsoft's DCOM I would expect to see support problems in future versions of windows.

UPDATE - VTScada OPC UA Client Driver now available as of VTScada 12.

It is included in all licenses at no extra cost. It is not counted towards your tag license limit.

From VTScada Help:

The OPC UA Client driver interfaces to an OPC UA server running on either the local or another computer.

OPC UA is an alternative communication protocol to OPC CLASSIC, which used DCOM for communication between a client and a server. VTScada still supports the existing OPC CLASSIC driver.

Unlike OPC CLASSIC, OPC UA, does not rely on third-party “OPC-tunnellers” to act as proxies between the client and server. An OPC UA server may run on a remote computer or be embedded in a smart device and can run on a variety of operating systems. Because there are a limited number of OPC UA products, a tunneller can be used to connect OPC UA clients to an OPC CLASSIC server.

If both client and server are using OPC UA, the only additional configuration necessary is to ensure that firewalls allow the correct ports to be opened. The port(s) in use are defined by the OPC UA server.

Unlike many other drivers, the OPC UA Client Driver does not use a Port tag to communicate with its device (OPC UA server). Due to the nature of the binary protocol, the OPC UA Client Driver has port handling built-in.
