Process automation protocols

Posted by Xavier Labels: Automation Protocols, plc

FOUNDATION fieldbus

Profibus - by PROFIBUS International.

PROFINET IO

CIP (Common Industrial Protocol) - Can be treated as application layer common to DeviceNet, CompoNet, ControlNet and EtherNet/IP

Controller Area Network utilised in many network implementations, including CANopen and DeviceNet

ControlNet - an implementation of CIP, originally by Allen-Bradley

DeviceNet - an implementation of CIP, originally by Allen-Bradley

EtherNet/IP - IP stands for "Industrial Protocol". An implementation of CIP, originally created by Rockwell Automation

EtherCAT

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

HART Protocol

Modbus RTU or ASCII

Modbus-NET - Modbus for Networks

Modbus/TCP

Modbus Plus

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

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

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

Mechatrolink - open protocol originally developed by Yaskawa.

MelsecNet/10, supported by Mitsubishi Electric.

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.

SERCOS interface, Open Protocol for hard real-time control of motion and I/O

GE SRTP - GE Fanuc PLCs

Sinec H1 - Siemens

SynqNet - Danaher

TTEthernet - TTTech

PieP - An Open Fieldbus Protocol

BSAP - Bristol Standard Asynchronous Protocol, developed by Bristol Babcock Inc.
