Clipsal Wiser for C-Bus Automation Controller (5500SHAC) has RTU and TCP modbus capabilities but AFAIK there is no direct C-Bus to Modbus converter.

Depending on what you need to do and how complicated it is there is no reason you could not do it in the logic engine - if you are only writing say a few coils or registers you could hard code them into the logic

I MICK

this is the problem
i have a modbus master

I have to be able to read but above all write some registers belonging to devices that communicate in c-bus

but this is the point

the idea is to be able to directly manage the c-bus controller on a modbus network

ie master modbus -converter - c-bus controller - devices

there is a converter capable of doing so

I don't think there is something that can do it directly between Cbus and Modbus.

However, Cytech just released a UCM/Modbus to interface with their alarm system. If you have a UCM/Cbus then there might be a way to use it between Cbus and Modbus with certain limitations. The UCM/Modbus only works with signed integers so anything larger would require clever programming or won't work at all.

HI INGO

I understand that there is no conversion in a single solution

but it's possible to a c-bus converter to bacnet and then bacnet to modbus converter

you know c-bus converters to backnet
