CM9001, LGX01 Logic Engine, or UCM/Logic can have ETh03 or wifi submodules plugged in to the main PCB. the plug in ETH03 or wifi01 submodules can act like a separate UCM/ETH03 to allow programming for Comfigurator or access by the Cytech app. This is very useful and saves cost compared to having another UCM.
After Scanning for Modules, the Controller Properties will show the Internal UCM version below the Comfort Firmware, as shown below. This shows that the Comfort model supports the plug in submodule, but does not mean that there is actually a submodule plugged in
The old CM9000 will not have the UCM Properties section
It is also possible to have a UCM (ETH03, US or wifi) installed even if there is an ETH03 or Wifi submodule plugged in to the controller.
For example you need to use a UCM in order to do a Firmare upgrade by UCM programming cable, or an installer may bring a UCM/USB to the site to do programming for convenience. The separate UCM should always be at UCM ID 1, as this special ID can be removed without causing a RS485 Trouble alarm. Other UCM ids will cause RS485 Trouble if they are removed.
The UCMs can be seen after a Module scan
You can log in to the UCM or the submodule on the controller by setting the IP address and Port in Options > Settings > UCM Connections
You can check which connection you are using in Transfer > System Information.
The 1st image with UCM Type 64 means Log in by the plug in submodule on the Controller UCM Type 64 means the built in UCM on the controller
The image below with UCM Type 10 means log in by the separate UCM. UCM Type 10 means the UCM USB, ETH03 or wifi
