Modbus TCP/IP timeout error - Mirco - 27.10.2016
Hi,
I use HomeLynk to communicate with an old central via Modbus TCP/IP and I have to use script, instead of integrate Modbus, because I have to manipulate datas before write or after read.
When I read there's no problem, but when I write, it returns a "Timeout Error". I tryed to use some Modbus TCP programs for test the communication and I notice that the central answers after few seconds but it answers.
How can I resolve this problem? Is there an istruction to increase the time that HomeLYnk wait until sending a "Timeout Error"?

Put mb:setresponsetimeout(seconds) after mb:setslave(...), adjust timeout value as needed.

Thank you!

Is there a way to do the same with the modbus tool?
RE: Modbus TCP/IP timeout error - admin - 02.12.2016
Do you mean in the profile? There's an optional timeout field which can be set, otherwise the default timeout is 3 seconds for TCP

Yes, how can I set it? In the manual I don't see any command for do this.. Where can I find the full list of possible command for the .json profiles?

You have to edit the profile and add "timeout": 10 after "manufacturer" field. Then you have to create a new device in with new profile for timeout to work. We'll probably make it configurable from the interface in new releases.
