Deep Dive: Modbus Busline Device Limits, Interference, and Best Practices

Modbus RTU, built on the RS-485 standard, is a widely used protocol in industrial automation due to its simplicity and reliability. However, as Modbus networks expand, understanding both physical and protocol limitations is essential for maintaining robust and interference-free communication.   Physical Layer and Device Limits The RS-485 standard is fundamental to Modbus RTU networks,…
