UCM/Cbus

Unrelated to this subject  but check out the new Universal UCM 6.010 firmware on http://www.comfortforums.com/forum99/2449.html

I just got home to find my Comfort system yet again not \'seeing\' any Cbus counter updates. A quick check confirmed commands from Comfort to Cbus goes through but nothing coming back from Cbus to Comfort. I am going to leave it untill tomorrow morning to see if it recovers.

I am already on the latest Cbus firmware, 6.010.

PS. Thanks to Julian for ComfortClient which aids in detecting this very quickly.

Are there are Busy1, Busy2 or ERROR leds on?
The new firmware basiaclly resets the SIM to a known state every minute so this state should not maiuntain for more than 60 seconds

[Ingo]

Yes, the Busy2 LED is permanently on.

[ident]

If you wait for 60 seconds can you see the Busy1 and Busy 2 leds flashing like they do after a reset? This shows that the SIM Module is being initialised, and he BUSY1 and BUSY2 leds will switch off leaving the RDY led on

[Ingo]

No, nothing happens at all. I watched it for 2 minutes. The only time the Busy2 LED goes off is when there is movement detected on my Garage PIR. Once movement stopped it goes back on. No other LED\'s flash except the RS485 BUS Led\'s and the Rdy LED being On all the time.

I think the reset routine might not be initialising.

Here is an idea: Can you not reassign the PP2 jumper to force a reinitialise when shunted? This way I can run the UCM without PP2 jumper and when I detect the issue I can manually reinitialise it. This is all assuming that your internal reinit routine doesn\'t fire when it\'s supposed to... This will at least prove that we are working in the right direction.

Just an update, getting home today the response restored by itself. When I checked this morning it was still broken but 10H later it fixed itself...

[ident]

Which SIM Module are you using?

The PP2 is a hardware jumper so it cannot be reassigned but something like that may be possible

[Ingo]

The new ST7 SIM.

[ident]

It looks like whatever caused the SIM to go into that mode also prevents the commands from changing the modes to the correct ones
The new firmware 6.011 goes 1 step further - if it fails to set the options, the UCM is reset so this should be foolproof

Also SW8H shunt when inserted will cause the mode stting commands to be immediately sent to the SIM instead of waiting for 60 seconds
