    Replace RS-485 with Siemens Profibus Cable

    Hi there. I am building a Modbus RTU network. I have 82 energy power analyzers. Different brands. Though 80% of them are Circutor (Spain manufacturer). All of them old models. By old i mean probably 10 years old. All of them have Modbus RTU available. The ones who have not will be replaced by...
