Ethernet I/O Modules: ADAM-6000 EtherNet/IP & Profinet I/O Module Introduction Real-time distributed control systems are an important technology for reliable industrial Ethernet and automation applications. A number of techniques are used to adapt the Ethernet protocol for industrial processes, which must provide reliable service to ensure stable operation. With modern protocols, automation systems from different manufacturers can be interconnected throughout a plant. Industrial Ethernet takes advantage of the relatively larger marketplace for computer interconnections to reduce cost and improve performance of communications between industrial controllers. Real-time Systems A real-time system is one in which the correctness of a result not only depends on precise calculations, but also upon accurate timing. In computing, real-time refers to a time frame that is very brief, appearing to be immediate. When a computer processes data in real time, it reads and handles data as it is received, producing results without delay. A non real-time computer process does not have a deadline. Such a process can be considered non-real-time, even if fast results are preferred. A real-time system, on the other hand, is expected to respond not just quickly, but also within a predictable period of time. In an automation control system, real time technology provides multiple advantages, such as improved safety, quality, and efficiency. To build a real-time distributed control system, it is critical to establish reliable real-time communication among the controllers, so there is now an increasing interest in the use of Ethernet as the link-layer protocol, such as EtherNet/IP, PROFINET, EtherCAT, Ethernet PowerLink, SERCOS III. EtherNet/IP EtherNet/IP was developed in the late 1990’s by Rockwell Automation for use in process control and other industrial automation applications, ensuring multi-vendor system interoperability. EtherNet/IP is a lot like standard office Ethernet, using the same TCP/IP messaging but with a new application layer added where data is arranged. This is known as Object-Orientated Organization, and allows ordinary office Ethernet to become a more versatile system. Today, EtherNet/IP is commonly used in industrial automation applications, such as water processing, manufacturing and utilities. Profinet PROFINET, the standard for industrial networking in automation, connects devices, systems, and cells, facilitating faster, safer, less costly and higher quality manufacturing. As it’s fully compatible with office Ethernet it easily integrates existing systems and equipment while bringing enhanced features such as real-time performance and control and monitoring functions as well as the ability to withstand harsh industrial environments. In addition to the above, PROFINET also features highly scalable architectures, remote access and maintenance of field devices over the network, and lower production/quality data monitoring costs. Feature Highlights Daisy Chain Connections Each ADAM-6100 module has two built in Ethernet switches to allow daisy chain connections in an Ethernet network, making it easier to deploy, helping improve scalability and improving resistance against interference common in factory settings. Ethernet-based Configuration Tool ADAM.NET Utility comes bundled with each ADAM-6100 module. With ADAM. NET Utility, users can configure, set and test ADAM-6100 modules through Ethernet. 2,500 VDC Isolation Protection With triple isolation, including power supply, input/output, and Ethernet communication, ADAM-6100 series ensures I/O data to be controlled correctly, and prevents devices from breaking down. Multiple Mounting Mechanisms Advantech provides versatile mounting methods to fit various demands in the field. ADAM-6100 series supports DIN-rail mounting, wall mounting and piggybacking.
