List of automation protocols

From Wikipedia, the free encyclopedia

Communication network protocols used for Building, Industrial and machine automation applications.

BACnet - for building automation, designed by committee ASHRAE.

CC-LINK, supported by Mitsubishi Electric.

ControlNet

DeviceNet - originally by Allen-Bradley

EGD (Ethernet Global Data) - General Electric Fanuc PLCs (see also SRTP)

EtherNet/IP - IP stands for "Industrial Protocol" Created by Rockwell Automation.

FINS, Omron's protocol for communication over several networks, including ethernet.

Host Link, Omron's protocol for communication over serial links.

Interbus, Phoenix Contact's protocol for communication over serial links, now part of PROFINET IO.

MelsecNet/10, supported by Mitsubishi Electric.

Modbus

Modbus-NET - Modbus for Networks

Modbus/TCP

Optomux - Serial (RS-422/485) network protocol originally developed by Opto 22 in 1982. The protocol was openly documented and over time used for industrial automation applications.

Profibus - by PROFIBUS International.

PROFINET IO

GE SRTP - General Electric Fanuc PLCs

Controller Area Network and CANopen

Industrial Ethernet

EtherCAT

LonTalk - protocol for LonWorks technology by Echelon Corporation

Sinec H1 - Siemens
