The OPC UA Client device driver works in conjunction with our OPC/Communications Server,
KEPServerEX to provide data access between OPC UA Servers and Client products such as HMI, Historian, MES and SCADA solutions.
The OPC Client Driver and the free
OPC UA Server interface for KEPServerEX provide an ideal OPC Tunnel solution. The tunnel uses a Client/Server architecture to transfer data over an Intranet, Internet, or WAN and provide a secure tunnel through firewalls. This tunneling solution is easy to use while being much more secure and maintainable than remote OPC connectivity via DCOM. UA (unlike DA) works over a VPN connection, and completely eliminates DCOM configuration and the need to expose applications to unauthorized or anonymous users. An OPC tunneling solution provided through KEPServerEX compliments existing OPC DA applications and now end-users, integrators, and automation suppliers have a much friendlier solution to remote connectivity for OPC applications.
The ideal solution for connectivity between distributed OPC Classic (DA) Clients and Servers is by pairing an OPC UA Client with a Remote OPC UA Server to create a secure and reliable communications tunnel.
