standards can be instal ed using fiber optic cable. Protocols versus Standards. Many automation professionals confuse an electrical standard like RS-485 or Ethernet (IEEE 802.3). with a protocol like Modbus or Profibus. Modbus was original y developed at Modicon, now Schneider Electric, in order
Configuring DT8x Data Loggers to Interface with Maple Displays via Modbus
and DT85 models support Modbus communication via either the serial sensor port on the front of the logger (1Serial) which allows RS-232, RS-485 or RS-422 communications or the host serial port on the side of the logger (2Serial) which is RS-232 only. When using the front serial port, a custom cable
