While Modbus RTU establishes the logic language of a serial industrial network, the electrical signaling relies entirely on the RS-485 physical layer. Unlike residential networks, field environment lines suffer from severe electromagnetic interference (EMI) generated by heavy electric motors, variable frequency drives (VFDs), and high-voltage conduits. To achieve zero-packet-loss diagnostics across hundreds of meters, field … Read more
