Numerous plants are now using Transmission Control Protocol/Internet Protocol (TCP/IP) and Ethernet network fabrics to increasingly replace proprietary protocols with integrated communication protocols to tie field productivity to business intelligence. The device layer network uses controllers to communicate between machines through popular open protocols and proprietary protocols. Implementing Ethernet as a link layer without legacy applications can improve boot time and optimize workflow and production, making the network ready for the future while increasing return on investment. High-density Ethernet/IP is compatible with the most flexible fieldbus automation technology. Ethernet/IP provides the scalability you need to cost-effectively integrate production facilities with enterprise-wide office facilities and beyond that range for secure remote access.
A networked Ethernet/IP architecture with industrial-grade components enables fully integrated connectivity through sophisticated control automation at the machine level, while mining multiple data streams from the production site for enterprise-wide business strategy. Ethernet/IP can meet the needs of communications without compromising reliability and security, and has become the gold standard in commercial industrial environments. Ethernet/IP facilitates fast, accurate data flow, provides shared communication over a single LAN, accesses the Internet, and integrates mechanical equipment and processes data in the plant via Ethernet or other compatible protocols.
Ethernet/IP overcomes the challenges of the field
The physical infrastructure of a networked factory floor is vastly different from the office environment. Building an enterprise-wide network requires integration of cabling, connectivity, controllers, switches, and other software, as well as software interfaces for data transfer and mining. Factory-level connections need to be implemented at longer distances, requiring more rigorous, faster real-time data rates. In areas where high speed and longer range lines are required, Ethernet/IP delivers outstanding performance without degrading performance.
The rapid development of technology has made Ethernet the mainstream enterprise-class communication technology. Any technology has both advantages and disadvantages. Enterprise-wide integration provides business intelligence, including real-time dashboards and data snapshots, for production planning, while providing advanced diagnostics and tools for quality control. Ethernet/IP enables real machine-to-machine and machine-to-business communication. The downside is the proportional increase in bandwidth resource requirements. Ethernet has this strength and potential in creating massive raw data that requires filtering control, segmentation, and analysis, as well as effective management to meet storage, redundancy, and security needs.
Ethernet/IP needs to implement strategic planning to meet the current and future data management requirements with the lowest integration cost and manpower while the company's network is expanding. Leading machine builders can provide non-proprietary, cost-effective Ethernet I/O device control systems and devices for greater interoperability. For a smooth network transition, accurate assessment of field devices, PLCs and other controllers and protocol implementations and software is critical.
The advantages of enterprise-wide convergence vary, depending on the company's goals and network configuration. To take full advantage of the full value of Ethernet/IP, you need to use the right components, including rugged industrial Ethernet switches, IO blocks, twisted pair or fiber optic cable assemblies. The network used in the environmentally controlled finished office space is not available, and industrial grade components are designed for harsh environments with extreme temperatures, humidity and vibration.
By improving reliability and extending service life, the higher initial cost of industrial grade components can be offset. Industrial grade RJ-45 connectors or newer M12 circular connectors are commonly used for long-haul Ethernet/IP, ProfiNet and EtherCat network cabling in the factory. Wireless Ethernet is especially suitable for remote locations and long-distance use and has been recognized in some process industries. Compared to traditional copper cables, expensive industrial grade cables offer extremely high speed, bandwidth, and noise protection over long distances.
Industrial-grade components such as Brad Direct-Link harsh environment unmanaged Ethernet switches provide reliable connectivity in harsh environments with extreme temperatures, humidity and vibration.
The right time to deploy enterprise-wide Ethernet
Some manufacturers and processors are too cautious about the approach taken by enterprise-wide network convergence. Many companies have adopted the same machine layer architecture or network architecture for decades, hesitating about whether to upgrade, even if there is a better solution, until outdated equipment causes failure. However, as manufacturers seek to improve operational efficiency and bottom line profits, the need to deploy more advanced field network technologies is becoming clearer.
The steady growth of automation and machine control through industrial networks has proven that the right technology can provide a significant competitive advantage to the processing and manufacturing industries at the right time. Both large manufacturers and process control operations tend to operate on enterprise-wide Ethernet platforms. Designing an excellent infrastructure reduces network security risks while providing transparency in real-time access to the site.
Factory equipment performance and production standards are widely recognized as important strategic business tools that help reduce expenses and optimize startup time. Ethernet/IP and industrial-grade connectivity are evolving at an affordable stage, delivering proven reliability and accessibility at an attractive price point. At the factory level, Ethernet/IP can make improvements in the following areas:
- equipment performance
- Workflow speed
-efficiency
-QC
- exceeds the data transfer speed of the original platform
- Add flexibility to remove network nodes
Advanced Ethernet/IP technology connects machines' processes, control systems and plant-level information to the enterprise with unparalleled scalability, functionality and options. The right architecture combines wired and wireless connectivity for enterprise-wide access, improved business intelligence, improved monitoring and control of production processes, resource management, and streamline operations.
