MODBUS Wiring Recommendations

MODBUS wiring should be selected such that the characteristic AC impedance (Z _) of the cable matches the impedance of standard transceiver chips. The most common RS485 twisted pair has an impedance of 100 ohms. Cables designed specifically for RS485 include Belden RS485 cable (98419844) or Alpha Wire (62226230). Cables with lower impedance will result in higher current draw from …

Arduino ArduinoModbus

Arduino Modbus Library. This library implements the Modbus protocol over two different types of transport: serial communication over RS485 with RTU (Remote Terminal Unit) or Ethernet and WiFi communication with TCP protocol. There are a few differences in the APIs depending on the transport, but the majority of the functions are the same for both.
