You still didn't tell us what didn't fulfill your requirements in these two implementations. You also didn't specify what these requirements are.
I have an SCADA system . That support MODBUS protocol. It like centralized system where we can connect no of devices. Now i have 2 arduino Which acts as slave.I want to communicate between two over mod bus protocol.
- I want to circuit connection for Modbus prtocol for arduino.currently i am having This set up
rs485 - Arduino as Modbus client with MAX485 doesn't get any response - Electrical Engineering Stack Exchange - I need simple example with library explaining modbus slave. Where i can assign slave id , slave address, function code etc, From Software i can read data. For testing i am using below software. I have already tested software with other modbus device . Since it mine first time to design Modbus slave I dont knoe how to do it in arduino.
