Hi - I have started a new topic as requested.
When I try to upload from PC to Comfort I am getting the error message Comfort or UCM firmware does not support scan function.
I am using V220.127.116.11 of Comfigurator.
When I try to update the UCM firmware (as advised) I get the message Firmware must be version 6 or above to upgrade by this method. Please use UCM Programming Cable instead.
what is the firmware version of Comfort and the UCMs?
If the firmware version is less than 6, then you will need to use the UCM Firmware upgrading cable to upgrade the firmware to the latest (version7). This will allow the scanning function to work
The firmware can be seen on the labels on the UCM and Comfort main microcontroller ICs
That explains the mystery
Comfort 1 firmware cannot be upgraded as it is based on OTP (One time program) ROM. You should be able to Add modules manually. The UCM and Comfort will not support the scanning function.
