We have Ignition works (7.5.6) installed on the same machine as KepServerEX5.11 and SQL. We have an inspection system with a separate PC that has an OPC server on it that we want to communicate with. If I am understanding this correctly I can:
Install Ignition (Only with the following)
on the inspection PC and communicate without DCOM to my main Ignition system. My main question is about the license. OPC-COM is licensed on the main system but do I need one on the remote system also?
Do I need the OPC Tunneller on both systems?
