Ideally, install Kepware on the same PC as your OPC DA server. If that’s not possible, install it on a PC/VM within the same network, ensuring there are no firewalls between the two machines. Kepware will use the OPC DA Client driver (part of the OPC Connectivity Suite) to connect to the OPC DA server and Kepware will provide an OPC UA Server interface that allows OPC UA client applications to access the data.

Components Needed:
KEPServerEX: This is the main Kepware platform that will host the OPC UA and OPC DA connections.
OPC Connectivity Suite: This suite includes the OPC DA Client driver and OPC UA Server capabilities

Steps to Configure:
Install KEPServerEX on the PC/VM.
Add OPC DA Client Driver: Configure it to connect to your OPC DA server.
Set Up OPC UA Server: Configure the OPC UA Server settings to allow OPC UA clients to connect and access the data.

Note: Try keeping Security  "NONE" in OPC UA connection and ensure the OPC UA port (default: 49320) is opened for outbound connections from the OPC UA client to the PC running Kepware.
