We are checking the Modbus driver again, possible fixes will be available in next update.

Hi, please check if you have any invalid addresses in you modbus configuration. Try to create new Modbus configuration with only few addresses for which you are sure that they are correct.

I'm looking into last night, the address are all ok. I change the moxa with a standard gateway (tibbo).

With the dimmer light no problem, everythings works right but with boolean I need to set "Read Cyclically" on "False" and I didn.t get any error. The problem is that I didn't get the real state of the light.


Any suggestion please?


Thanks in advance

Best regards

Did you try with any other Modbus monitor to see if you get the state?

We having the same problem here

we using KNX IP Routers and a TCPIP Modbus connection to a BMS System (SHE RCM)

Thru Modbus Commands we are switching KNX Groups on the other side

Whenever there is a Communication Problem to 1 of our KNX Ip Routers (no Power) as well the Communication to the Modbus also goes on error for 15sec and connect back.

It is for sure not a Network Problem we have checked with Wireshark


This is only happen after the last update before it was running normal without error on the modbus side
