EtherCAT (Ethernet for Control Automation Technology) is an Ethernet-based fieldbus system developed by Beckhoff Automation. The protocol is standardized in IEC 61158 and is suitable for both hard and soft real-time computing requirements in automation technology.
Protocols for industrial Ethernet include EtherCAT, EtherNet/IP, PROFINET, POWERLINK, SERCOS III, CC-Link IE, and Modbus TCP. [1] [2] Many industrial Ethernet protocols use a modified media access control (MAC) layer to provide low latency and determinism. [1] Some microprocessors provide industrial Ethernet support.
CLPA offers a variety of open automation network technologies. These are the CC-Link fieldbus, CC-Link Safety fieldbus, CC-Link IE and CC-Link IE TSN. Compatible products include industrial PCs, PLCs, robots, servos, drives, valve manifolds, digital & analogue I/O modules, temperature controllers, mass flow controllers and others.
Here we find the solutions Ethernet/IP, three versions of PROFINET IO - the classes A, B, and C - and the solutions of P-NET, [28] Vnet/IP [29] TCnet, [30] EtherCAT, Ethernet POWERLINK, Ethernet for Plant Automation (EPA), and also the MODBUS with a new Real-Time Publish-Subscribe MODBUS-RTPS and the legacy profile MODBUS-TCP.
The IO-Controller, which controls the automation task. The IO-Device, which is a field device, monitored and controlled by an IO-Controller. An IO-Device may consist of several modules and sub-modules. The IO-Supervisor is software typically based on a PC for setting parameters and diagnosing individual IO-Devices.
IO-Link is a short distance, bi-directional, digital, point-to-point, wired (or wireless), industrial communications networking standard (IEC 61131-9) used for connecting digital sensors and actuators to either a type of industrial fieldbus or a type of industrial Ethernet. [1]
EtherCAT; 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).
An IO-Link master can be either a stand-alone slave or part of a modular slave device. An IO-Link-to-Sercos mapping guide [13] is available to assist manufacturers in integrating IO-Link into a Sercos III network. An IO-Link development board with an IO-Link master and a Sercos III slave interface is available.
