Hi,
I’ve using Velbus in my home for 3y now and yesterday suddenly all stopped working.
I don’t know the root cause (maybe power peak due to lightning) but I don’t see any visible damage.
I tried to isolate the problem by splitting the bus in smaller parts and performed following tests.
- The local inputs of relais VMB4RY are luckely still working (power led still fine)
- With the VMB1USB I can detect TVMB1TS and TVMB4PD if no VMBRY in the bus
With VMB4RY I receive error:
The Velbus network could not handle the current traffic load and has entered an erroneous state.
I tried several combinations with terminators on/off 1 & 2 terminators, 1 & 2 VMB4RY (PDVMB4RY) modules.
VMB1USB is performing scan, but no feedback from modules.
Traffic log:
receive:
Addr. 00
Command RS232 buffel full
Data OB
Priority High
Raw 0F F8 00 01 0B ED 04
Send (sending scan packages ok), no feedback
Addr: F0
Command: Scan
Rtn: on
Priority: Low
Raw: 0F FB F0 40 C6 04
Extra notes:
- TX led is blinking continuous less bright than PS led.
- VMB1USB is feeling hot, not sure if this was in the past as well, maybe bringing yitter to the bus? (althoug working fine with TVMB1TS and TVMB4PD)
- I unplugged power for +30s from the bus to reset bus
- I checked/exchanged cabling
- I updated Velbuslink to latest version but never performed firmware upgrades on the modules
Questions:
- How to get rid of bus “entered an erroneous state” - reset options (power/ special buttons) ?
- Can I send modules VMB1USB / PDVMB4RY for repair?
- Can I perform firmwarefix in field as I don’t want to disconnect +30 modules and redo cabling
- Do I need to purchase VMBRSUSB based on above? and retry testing.
- Any option for support on site (in Belgium/Limburg) as I don’t know anymore how to fix the issue.
Thx for the fast feedback,
We are sitting in the dark.
Thx,
Maarten
