Please help me diagnose my C-bus network issue

Hi,

I've got a C-bus network that generally works okay via the buttons and a keypad, however I want to interface with the system using C-gate.

When I try and connect to the network using the C-bus toolkit and I try and view the units on the network, the scan runs for about 30 seconds then comes up with an error dialog:

"Network Scan failed
Check Network power, burden, C-Bus Interface connection"​

Using a telnet connection to C-gate directly, I get the following output from the tree, and sync commands:

tree 254
320- Network name:254 type=cni address=10.1.1.9:4001 state=error
320- Unit count=0
320- Units:
320-Applications:
320- Application 31 ($1f) [application]
320- Groups:
320- Application 56 ($38) [lighting]
320- Groups:
320- //NETWORK/254/56/10 ($a) level=0 state=error units= (phantom)
320- //NETWORK/254/56/16 ($10) level=255 state=error units= (phantom)
320- //NETWORK/254/56/31 ($1f) level=0 state=error units= (phantom)
320- //NETWORK/254/56/34 ($22) level=255 state=error units= (phantom)
320- //NETWORK/254/56/35 ($23) level=255 state=error units= (phantom)
320 -end-​

net sync 254

120-Net Sync: synchronising PCIs
120-Net Sync: starting network discovery
120-Net Sync: Network sync duplicate detection failed.
408 Operation failed: sync failed​

I don't seem to be able to switch lights on or off either (I imagine because of the other errors):

off 254/56/31
408 Operation failed: //NETWORK/254/56/31​

What else can I try to see what is going wrong on the network?

 

I ran the diagnostic utility to get the following details about the network:

Firmware version: 5.4.00
C-Bus Voltage: 28.1V

From the diagnostic utility, I'm able to switch lights on and off, and ramp them up and down.

 

Running a net sync 254 via telnet I get:

net sync 254

Hi,

I'm using Toolkit version 1.14.1, and C-Gate version 2.10.0.
The diagnostic utility version is 2.1.0.0.

Thanks

 

Hi MrMcBerry
I wonder what interface you are using to connect to CBus or if you have multiple applications trying to connect at once.

 

Hi,

That seems to be what the issue was; I am connecting to C-bus via an Axium R4 router which is acting as the C-bus CNI. When I unplugged that, and connected via the rs232 link, everything began working perfectly.

Thanks very much for your help.
