hello friends

as i know , we can implement modbus protocol in bus topology.

but i think we can implement modbus topology in star topology too.

i think in shared media it works, is it true?
please look at the attached diagram.

for using radio modems instead of wired media, we have to configure our network in star topology, doesn't it?

thanks

Did it work in star topology ? Any special settings ?

The base definition of an RS485 network would tell you what is possible. Some discussion on that can be found: Is Star Topology of MODBUS-RS485 Possible?
