does knxlib.ping('1.1.0') require TP1 connection? - kropfm - 12.08.2020
Hello
I seem to be totally talent free when it comes to scripting. I've used the following code to check the existence of the IP/TP couplers . But get all 'falses' as a result in the log, when in fact only one of them is offline, 1.4.0. I must add that my LM is connected to the bus through IP. Does it require the TP1 bus connection? I get no errors, just false results.
Code:
result1 = knxlib.ping('1.1.0')
sleep(3)
result2 = knxlib.ping('1.2.0')
sleep(3)
result3 = knxlib.ping('1.3.0')
sleep(3)
result4 = knxlib.ping('1.4.0')
log(result1,result2,result3,result4)the results:
* arg: 1
* bool: false
* arg: 2
* bool: false
* arg: 3
* bool: false
* arg: 4
* bool: false
Look forward to hearing from you.
Cheers!
Martin

Yes this works only via TP.

You can disable KNX IP, or change multicast.

Or are you saying I could use an IP tunnel?
RE: does knxlib.ping('1.1.0') require TP1 connection? - Daniel - 12.08.2020
I'm guessing that you have another IP router on the TP and this is why you had the repeats. When multicast is different on both routers then they will not see telegrams on IP from each other and you will have no repeats.

yes, the 4 line couplers are all IP on the main line. If I now change the multicast address of the PM I wouldn't be able to visualize the data points, group addresses. It would be like an independed network.

ok then you need it on IP only.
RE: does knxlib.ping('1.1.0') require TP1 connection? - kropfm - 12.08.2020
thanks Daniel, I solve two problems now. I activated the TP1 connection and turned off the IP feature. Now I get the correct status from the couplers and have no added repeats on the bus. They could've mentioned this in the manual.
Thanks a lot!!
