knx/tp error - Gabi - 28.02.2018
The following messages will appear in the error Log: 1. KNX/tp Temperature Warning;
2. Transmitter Error(send 0 receive 1).
The following messages will appear in Alerts: 1. KNX/tp Connected;
2. KNX/tp Disconnected.
Messages appear at the bottom of the main window KNX/tp ERROR.
A full reboot of the automation Cabinet helps for a while, but the error occurs again.

OK old one. Can you open it and check what is written on KNX chip? In this LM it will be Siemens and version can be 5.2 or 5.3.

as i know there was no TPUART 5.3 on LM3, only 5.2 was
RE: knx/tp error - Gabi - 02.03.2018
Siemens KNX UART v5.2

There is known issue with this chip. Siemens fixed it in version 5.3.
In certain conditions the issue which you described is happening.
Check voltage on KNX as above 30V this was happening. The biggest issues were with combination of SE KNX PSU.
Check if you don't have some script which is creating a knx loop
Check if some device on KNX network is not spamming the bus.
If nothing help we could replace this chip on your LM. I assume your device is out of warranty already as it is old one.

You are ready to change the chip for free with expired warranty?
RE: knx/tp error - Daniel - 12.03.2018
Have you checked all the points I asked you for?
RE: knx/tp error - Gabi - 20.03.2018
Yes.
1) Bus voltage KNX 23.2V (PSU Mean well dr-24-30 together with PSU for knx bus EVIKA (CHOKE-KNX)).
2) Errors "Transmitter Error(send 0 receive 1)" occur in other LM's in the serviced building.

Dear Edgar,
I have checked all that you refer above. All ok except that the chip is version 5.2
I am trying to send you a photo, but the max for files is 500KB.
Do you want to send you by e-mail?
Thanks in advance
RE: knx/tp error - DGrandes - 26.10.2020
Hi!,
I have the same problem with an new Logic Machine and newest firmware.
KNX/TP: Transmitter Error (send 0 receive 1)
Any Idea?
RE: knx/tp error - Daniel - 26.10.2020
Is your bus very busy?
RE: knx/tp error - DGrandes - 27.10.2020
No, it's a house.
RE: knx/tp error - admin - 27.10.2020
This can happen if the line is overloaded with too many devices, how many do you have there?
RE: knx/tp error - AlexLV - 27.10.2020
Hi,
also seen the same at customer SL, now with 1.5.1 fw, not to old - ap 2 years... But not take attention to it - all functions are working fine..
But what does mean ''too many devices''??
I had other problem - very long KNX lines.. Not possible to divide it... I just added second KNX Power Supply to one line end, and first one reinstalled to other line end and finally all works. Not a very good solution but possible and solved problem..
