I’m looking for upgrading existing products equipped with MODBUS RTU over RS485 and I’m curious wether I can easily upgrade it to MODBUS TPC using WIZ750SR-485 module.
However it is mentioned that this module support Modbus I have read fast documentation available and can’t find detailed algorithm what to do or set up to get small with possibility to built into other device
module which provide me in first step MODBUS RTU to TCP conversion.
