Modbus RTU slave mode #69

Closed j123b567 closed 3 years ago

Is it possible to run mbusd in reversed mode? So

on one end, mbusd is TCP server as it is now, but in Modbus/TCP master mode
on the other end, mbusd is connected to RS-485 and behaves as Modbus/RTU slave

So, basically, if there is some "dumb" mode, where mbusd just understand Modbus/RTU framing, crc and not the content and pack/unpack messages to/from TCP.

Sorry, but currently mbusd acts only as a gateway from TCP to RTU network, and reverse mode is not supported.

Ok, thank you.
