COMMUNICATION PROTOCOLS
INDUSTRIAL COMMUNICATION PROTOCOL
Either we like to be a System Engineer that understood well the intricacies of computer communication or not, it is one of the duty of anyone involved in Electrical Control, Instrumentation and Automation to be familiar with the aspect related to their field in which now i will discuss with you.
Listed below are the list of communication protocol as formulated by different vendors but the most commonly used in the Industrial machine application to connect PLC, HMI, Drives, Field devices, and more are ETHERNET, PROFIBUS, DEVICENET, AS-i, PPI, MPI, POWERLINK, ANYBUS, CANBUS, PROFINET, BacNet, HART, MODBUS, SERCOS
COMMUNICATION PROTOCOLS
AS-i : Actuator-sensor interface, a low level 2-wire bus establishing power and
communications to basic digital and analog devices
BSAP : Bristol
Standard Asynchronous Protocol, developed by Bristol Babcock Inc.
CIP : (Common Industrial Protocol) –
can be treated as application layer common to DeviceNet, CompoNet, ControlNet and EtherNet/IP
ControlNet : –
an implementation of CIP, originally by Allen-Bradley
DC-BUS : –
communication over DC power lines, originally by Yamar Electronics Ltd
DeviceNet : –
an implementation of CIP, originally by Allen-Bradley
DF-1 : -
used by Allen-Bradley ControlLogix, CompactLogix,
PLC-5, SLC-500, and MicroLogix class devices
DirectNet : – Koyo / Automation Direct
proprietary, yet documented PLC interface
EtherNet/IP –
IP stands for "Industrial Protocol". An implementation of CIP, originally created by Rockwell Automation
Ethernet Powerlink – an open protocol
managed by the Ethernet POWERLINK Standardization Group (EPSG).
FINS: Omron's protocol for
communication over several networks, including Ethernet.
HART Protocol
HostLink
Protocol, Omron's protocol for communication over serial links.
Interbus,
Phoenix Contact's protocol for communication over serial links, now part of
PROFINET IO
IO-Link,
for sensors, actuators
MECHATROLINK –
open protocol originally developed by Yaskawa,
supported by the MMA
MelsecNet,
and MelsecNet II, /B, and /H, supported by Mitsubishi Electric.
MPI – Multi Point Interface
Modbus PEMEX
Modbus RTU
or ASCII or TCP
OSGP – The Open Smart Grid Protocol,
a widely use protocol for smart grid devices built on ISO/IEC 14908.1
OpenADR –
Open Automated Demand Response; protocol to manage electricity
consuming/controlling devices
Optomux –
Serial (RS-422/485)
network protocol originally developed by Opto 22 in
1982. The protocol was openly documented[2] and over time used for industrial automation
applications.
PieP – An Open
Fieldbus Protocol
PPI - Point to point interface
Profibus –
by PROFIBUS International.
PROFINET IO
RAPIEnet –
Real-time Automation Protocols for Industrial Ethernet
Honeywell SDS –
Smart Distributed System – Originally developed by Honeywell.
Currently supported by Holjeron.
SERCOS III,
Ethernet-based version of SERCOS real-time interface standard
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
