Modbus TCP/RTU
Connectors BSD-3-Clause (Free)
About
Modbus is the most-deployed industrial fieldbus protocol. The Paramus Modbus connector uses pymodbus to act as a Modbus master, communicating with slave devices over Modbus TCP (port 502) or Modbus RTU/ASCII over serial. Reads and writes coils, discrete inputs, holding registers and input registers (function codes 01/02/03/04/05/06/15/16). Configurable slave ID, timeout and retries. No vendor license required.
