CODESYS can not connect to FactoryIO

I can not connect KEPServerEX (OPC UA)

OPC Server is already start

Unable to display server list

please help


The Host Name input field should be used to specify the machine’s name where to browse for OPC Servers. You should leave it blank when browsing for local servers.

The OPC Server list should display all servers available in your computer. If you can’t find it in this list, it means it’s not properly registered in the OPC Local Discovery Server (LDS) (or you don’t have an LDS installed in your system). If this is the case, check the server endpoint URL in the OPC Server and type it in the OPC Server input field - press Enter to connect.

Btw, are you trying to connect to KepServerEx or Codesys?
