Thanks Ingo,Slychui
General update, I disconnected the suspect vmb4ry module from the velbus system today, and everything g has worked 100% ok so far.
It does indeed look like the velbus module was causing the problem, a very weird problem.
Anyway, hoping to have a new module by the end of the week to swap out and this should give a final answer, and I will send the faulty one back for repair.
Regards

I hope they will feedback what the problem was. We would like to know what caused this

Will definately ask them to provide details. Day two now of full service with no issues and the vmb4ry disconnected

ok,
Update as follows. Shortly after the post above, I started to have problems again, and it really confused me, as the vmb4ry was completely disconnected from the system, the only thing common was the 12v power whcih was still powering the vmb4ry so I could retain local control.
I ignore the issue, as I had a new vmb4ry on the way, and this would eliminate the module as faulty or not.
Anyway, christmas eve, the new module arrived, it was in fact a vmb4ryno, which is pretty much the same module, just to local PB inputs. I replaced it for the suspect one, updated comfort and left to see how things panned out.
That evening, the problem came in again, comms failure.
So, fairly confused now, I am just simply working my way through replacing parts to eliminate as much hardware as possible.
Yesterday I swapped the ucm board that my eth was connected to (re-used the daughter board), and the problem still recurred. The event log shows UCM2 (the velbus ucm) as the main/first module to lose comms, so that was next on my list.
I have replaced the ucm velbus, but cant upgrde the firmware to ucm velbus, as it is showing as a ucm general.
Can anyone advise how I do this it was formerly a ucm usb, so I am simply replacing the daughter boards).
Regards,

You cannot change a UCM/USB firmware to a UCM/Velbus. You can only upgrade the firmware to the same type
I dont think the fault is with the UCM/Velbus
What triggers the fault now? Is it the switching on of the relays?
Can you switch on the velbus relay manually and not from Comfort? Does that cause the problem?

hi, waxfordman
I noticed from your post: "from the system, the only thing common was the 12v power whcih was still powering the vmb4ry"
so you power the VMB4RY or VMB4RTNO input (12V) by comfort system? if like this, maybe your problem is due to this...
just ignore my post if the relay is powered by velbus system...

Hi slychui,
The fault still seems to be trigggered by the heating going on (whether manually or via comfort) but it does not seem to recover if i turn it off again.
Last night, the problem occurred and no matter what I did to try and restore comms I could not. I disconnected every keypad and scs switch via removing the ka/kb and 12 power out from the main board. I also disconnected the ucm velbus. At that point the only items connected were the main board lem and ucm eth, and I could not connect to the system even after restart. (By this I mean I could not connect comfigurator to log in to the system, nor connect a phone via the app.
All this time, and trhiughout the night however, comfort performed all macros etc so was not frozen. For example there are pir activations which aactivate velbus lights and turnnthen off again after timers expire etc.....all this worked fine, so comfort continued to work this way, which indicates velbus ucm was fine and main board was fine.
The system is still down, but I expect it to recover at about 9amLast edited on Wednesday Dec 31st, 2014 12:04 pm by wexfordman

Hi hefeng,
The velbus modules are powered by a separate 12v/15v power[size= supply which is independent of comfort (it does power the ucm velbus daughter boardbi think though.)]

If you completely disconnect UCM/Velbus from Comfort and turn on the relays with Velbus does it still happen?

I can try that this evening, but put it this way. When I completely disconnect the ucm velbus I still cannot get comfort to recover.
Comfort will recover now at about 9am.

Just to put some definate times on this, the event log over the last few days shows
29th: comms failures start at 16:57 with keypad 2, and continue on for all modules until the comms failure stops recurring at 08:37 the following morning (30th)
30th:- Comms failures start, again at 16:57 with scs 01, and continue for all modules until comms failure stops the followign morning (31st) at 08:35
I will now disconnect the ucm velbus from comfort, and remove the ucm from comfigurator. Will leave it in this state until tomorrow am, and report back with any changes etc.
Event log is attatched (ignore the mid -day comms failures for the 30th, this was me trying to replace the ucm velbus with a ucm usb main board) and a keypad
Regards,Eamon

Okay, update again.
With ucm velbus disconnected from comfort AND velbus bus no alarms came in a expected time (around 1:57). The heating relay was off at this stage
I then turned on the heating relay manualy (bearing in mind, that comfort now has absolutely no connectivity to the velbus system), and I lost comms!
I am absolutely stuck on this, I simply cannot explain it.
Bus monitor file enclosed, you can see the issue come in at about 17:07

The NAKs appear around 17:07 and stop at 17:08:21
After that the commuications seem to be fine. The keypad and RIO/SCS are being polled and reply is received. So you should be able to use the system after that time

I could not connect to eth, I had to restart the system by disconnecting power and battery before I could connect again.
I have two more tests to do, I am going to have the vmb4ry on its own 12v power supply independent of the other modules and see what happens.
After this, I can only think that perhaps the load side of the heating is introducing interference in the comfort bus somewhere, so I will try and trace the Gnostic to see if I can find a cross over.

Okay,
Latest update, this issue is still happening. Today as expected, the comms failures started once again like clockwork at 5pm.
Tonight, I rewired the heating ac supply via a different route, bypassing the mcb that was feeding it and still no change.
Whenever the oil burner kicks in, I get comms failure in comfort (between 5pm and 9am).
It looks like I am going to have to get an electrician in to see if I can completely rewire the heating, and possibly remove it from comfort altogether...I've run out of ideas...it's been like this and working fine for nearly fifteen years, and the last month has me dumbfounded.

It does look like the oil burner is causing interference to the RS485 bus. The bus is normally very robust as it is differential and very noise resistant so it takes a lot of interference to affect it
I think it should be looked into as there may be other effects

One leg of the RS485 touching ground somewhere? Check all the places where the RS485(KA/KB) cables route through between ALL the different modules. Check connectors also, one might be loose etc.

Thanks all, will do a bit more digging. I would be in agreement to the ibterfer nxe issue, but the regularity of it has mendkubting. 5pm start, 9am finish, pretty much gauranteed.
