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 Global Data (EGD) – GE Fanuc PLCs (see also SRTP)

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

Methods of starting Squirrel Cage Induction Motors

Image
METHOD OF STARTING ELECTRIC MOTOR There are several method of starting Induction Motor namely: ·      Direct on line starter commonly called DOL ·          Star Delta starter ·          Rotor resistance starter ·          Stator resistance starter ·          Forward and Reverse starter ·          Auto transformer starter ·          Frequency inverter starter .      Servo starter ( position/timing based) Before exploring the methods mentioned above, it is of higher importance to understand very well the makeup of an electric motor with emphasis on Three Phase Motor. There is virtually no process or packagining equipment that could operate in the industries without the need for motion transmissi...

PROCESS CONTROL ACTUATOR

Image
PROCESS ACTUATOR Actuators are devices that are directly connected to control device in the field to achieve control actions. It may be coil, lamp, relay, vibrator, solenoid valves, cylinders, electric motor, pump, and so on. Another name for output devices is ACTUATOR. They are powered with any of this form of energies electrical, pneumatic and or hydraulic energy. Some actuator performs action without given feedback to elements controlling them while some gives feedback about their current position or status of mechanism they are attached to. Some actuators make use of digital output signal to perform operations while some uses analogue signals to perform operation. Some makes use of only one source of energy to initiate control actions while some combines two sources of energy to initiate control actions such as pneumatic and electric power as in the case of pneumatic components . Some actuator can convert mechanical rotational motion to linear moti...
