Today I tried to update my comfort system and while exporting (writing) cclx file from PC into comfort I encountered this error\"Failed to write to UCM\"
Error keeps repeating no matter how many times I try.
My system is still using UCM ETH02 though I have order a new UCM ETH03, it is not going to arrive till end of next week. I have lost control over most of the lights and curtains in the house so if I get UCM ETH 02 updated with a new cclx file I might get temporary control over the system till new UCM arrives. Any help to sort this will be much appreciated.
There may be a problem with your network, or possibly a fault with the old ETTH02
make sure you have the original cclx file which was used to program the system so you can write to Comfort when the new UCM arrives.
Thanks Chui,
Checked LAN (ping working fine) plus I could execute few commands from comfigurator (like closing blinds and turn off lights).
I can read from Comfort to PC but can\'t write back.
I guess it may be UCM ETH02 is faulty, will come to know when I install new UCM ETH03 next week.
Hi Chiu,
Got ETH03 today, installed it (after taking old ucm out) and uploaded the original cclx file into comfort without any trouble.
I still dont have responses (PIRs and lights turning on, nor curtains moving).
The comfig software shows UCM 02 ( UCM/CBUS) \"not supported by firmware\"When I tried to update its firmware, I cant because during the process system asks for F0 at keypad before it can update. My keypads are greyed out at comfig and pressing Fn plus 0 on keypad doesnot seem to do anything.
Please see photos attached
Appreciate your help.
Thanks Muddi
Thought it could be issue with ID of UCMs and keypads.Tried scan all modules and \"write module and settings to comfort\" but again F0 and engineering code is not working ( i am using default Fn plus 0 on key pad and 6789 as engineering code on PC).
You need to press F0 on any keypad in order to allow firmware upgradeThis means pressing the F key folliowed by them0 key in the physical keypad
Then do the upgrade
F plus 0 on keypads (tried all three) was not working. Finally managed to enter engineer mode by executing it through Comfigurator (in the response tabs) and that did the trick.
Managed to update firmware of UCM Cbus and then uploaded cclx file again.
Had to do it few times as not all functions were copying (especially the curtains).
Did \"selective write\" couple of time and eventually got all it written into comfort.
Looks good now, all PIRs, curtains, and lights are working fine. Alarm functioning OK!!
Just have to update my cclx file to make it work with android app.
Thanks for your prompt help Chiu.
If F0 did not allow upgrade, it is probably because the function for Key 0 was reprogramed from default
Anyway gfood that you got it working
