Process automation protocols

• 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.
