oldtag: null newtag: null

I'm trying to turn off a light via cgate:
project load BITMEAD
project use BITMEAD
net open 254
off bed1
408 Operation failed: //BITMEAD/254/56/31

and the cgate server is printing this error:
20070625-010551 751 //BITMEAD - Tag information changed at tag address: //BITMEAD/Installation oldtag: null newtag: null
20070625-010552 804 cmd27 - Host:/0:0:0:0:0:0:0:1%0 closed command interface from port: 49507

Strangely, if I go into cbus toolkit, turn the light on and off using the gui, and then do the above telnet session again, it now works, although the server still prints the error. Even after I shut down the toolkit it still works.

However, if I then restart the cgate server, and do it again, it fails again.

 

If the network hasn't synced yet you will need to force the write of the command

Code:

lighting 254/56/31 off force

you can check the network sync state with the command

Code:

get 254 state

and look for a state of sync.

 

Going off your detail above you have not started the project properly. Your initialise code should be;

Code:

project load BITMEAD
project use BITMEAD
project start BITMEAD

This shoud get things singing

PS. Depending on the number and size fo the C-Bus networks it may take minutes for C-Gate to build its model.

Open a telnet session on IP address of C-Gate (localhost if same machine)<space> 20024 and watch the network build.
I have my global event level set to "9"

 

Issuing a project start is not necessary for issuing lighting commands. As long as the network is in the "OK" state all should be fine. I recall that the start command only has an effect on some inbuilt scene features in C-Gate, and maybe some other uncomon stuff. All of which are largely not recommend for use and somewhat obscure. I doubt many (if any) CIS created client applications even issue a project start.

I know better than to disagree with you Richo, however, just last week spent two days playing with C-Gate is support of writing an engineering brief for one of our guys. C-Gate did not start modeling the project until I called project start (situation where Toolkit or SP had not previously opened networks). I was sending commands to a bridged network (253) and it definately would not play until I called project start (n).

If I set the project via the C-GateConfig.txt file then there is no need to call project start.

Am I doing something wrong

 

Hmmm, Interesting. I will have to follow this up with Daniel. I have been known to be wrong in the past.

Certainly there would be no detrimental effect to calling project start.
