The OPC-COM Tunneler module eliminates many difficulties associated with establishing remote OPC-COM connections. The OPC-COM Tunneler module exposes OPC-COM connections to Ignition's OPC-UA server. The connections appear and behave as devices connected to Ignition's OPC-UA server. In this way, Ignition manages the OPC-COM connection in the context of the OPC-UA standard resulting easier access over the network, eliminating the need to establish remote DCOM connections, and incorporating the security benefits of the OPC-UA standard such as authentication and encryption. This module can be considered a "UA wrapper" for classic OPC servers.

The following picture illustrates how this module can fit into your architecture.
