modbus, modbus/Jbus


Thread Starter


I have to develop an application with some equipments designed for modbus protocol and others designed for modbus/Jbus. Is there a risk to combine that?

Hello Padiri;

To my knowledge, there is none. We do it all the time. They both accept the same commands and standards. The only thing you have to be aware of is that J-bus registers addressing starts at xx001, while Modbus starts at addess xx000 (sometimes you have to do a few adjustments to find the correct value you wnat to examine) but it is very minor.

Hope this helps,
Daniel Chartier
