Software helps industrial network communications
Industrial network stacks and other industrial connectivity software work to enhance connectivity among devices and systems. OPC UA, MTConnect, EtherNet/IP, and CC-Link are among software that organizations provide. Middleware also provides connectivity between the plant floor and other systems.
Network stacks provide industrial network connectivity; middleware also can provide communication functions among devices and systems. Better communications helps the Industrial Internet of Things (IIoT), Industrie 4.0, and other frameworks designed to enhance industrial productivity.

Summaries: Industrial network connectivity
Six related articles in the Control Engineering January 2019 print and digital edition provide more information along with summary information below.
OPC United Architecture (OPC UA) from OPC Foundation is a platform independent service-oriented architecture that integrates all functions of the individual OPC Classic specifications into an extensible framework. It was released in 2008 and is IEC 62541.
MTConnect from MTConnect Institute: “Running machines, controls, sensor packages, or software that support the MTConnect standard means shop data is available in XML format with data item definitions that don’t vary by manufacturer.” The organization has a standards committee that advises on enhancements and oversees new capabilities.
EtherNet/IP from ODVA “provides users with the network tools to deploy standard Ethernet technology (IEEE 802.3 combined with the TCP/IP Suite) for industrial automation applications while enabling Internet and enterprise connectivity.” Like other ODVA Common Industrial Protocol (CIP) networks (DeviceNet, CompoNet, ControlNet), EtherNet/IP uses CIP for its upper layers, following the Open Systems Interconnection (OSI) model, which defines a framework for implementing network protocols in seven layers: physical, data link, network, transport, session, presentation, and application.
CC-Link from CC-Link Partner Association (CLPA) is an “Open-technology fieldbus network with performance up to 10 Mbps providing absolute deterministic behavior and cost effectiveness, flexibility and ease of use.” CC-Link IE TSN (uses IEEE Time-Sensitive Networking) technology for Ethernet bandwidth time sharing and priority control can help build flexible IIoT systems, CLPA said.
Kepware from PTC: KEPServerEX is a connectivity platform that allows users to connect, manage, monitor, and control diverse automation devices and software applications through one user interface using OPC and IT-centric communication protocols (such as SNMP, ODBC, and web services) to provide users with one industrial data source.
