How to disable read only mode in Sigen Plant?

[LukeHartcher]

I have checked HA versions are up-to-date and using the latest plugin (installed today).
I have installed the plugin with read-only mode and all the read-only items are working through modbus tcp correctly.
I now wish to start some automation, but I keep getting read-only messages in the debug log.
I have enabled the "Remote EMS (Controlled by Home Assistant)" and "Remote EMS Control Mode" but whenever I try and use these, they do nothing and I get the read-only messages in the debug logs.
I can see that people are saying you need to disable read-only mode in the Plant - but how!? I have looked trough all the UI options I can see but cannot see it anywhere!
Can anyone assist in where this setting can be changed?
