EtherCAT is becoming the most popular machine protocol. Why? Unmatched performance, the highest precision, and real openness make the difference compared to other Ethernet industrial protocols.
EtherNet/IP is an excellent network for controller-to-controller applications, with a natural integration into corporative networks. Using standard EtherNet hardware, EtherNet/IP is the perfect factory automation network where the data size exchanged by the node is high. EtherCAT exhibits outstanding performance with devices that exchange few numbers of bytes but require very deterministic and fast communication cycles. In addition, due to the ‘on the fly’ data exchange, EtherCAT is hardly affected by the number of nodes; it is the perfect machine network.
“One machine control over EtherCAT through one connection and one software is how we define the Sysmac automation platform,” says Omron’s Evert Janse van Vuuren. Omron’s Sysmac automation platform uses EtherCAT as its primary factory network and it provides seamless machine control and factory automation.
“Manufacturing is changing. Production lines need to be increasingly flexible to cope with shorter production runs, more varied products and tight deadlines. Manufacturers are addressing these challenges with more advanced, interconnected, and intelligent systems that can be programmed to handle a variety of tasks. One machine control over EtherCAT through one connection and one software is how we define the Sysmac automation platform,” he says.
Omron’s EtherCAT solutions include products for logic, motion, safety, robotics, vision, information, visualisation, and networking − all under one software platform. This has brought new challenges, such as how to program all these devices without needing to learn many different systems and programming languages. Fortunately, there are tools out there, such as Omron’s Sysmac Studio, that offer fully integrated development environments (IDE) for configuration, programming, monitoring and 3D simulations. The machine controller used comes standard with built-in EtherCAT. The EtherCAT network can be accessed with one connection, and is the perfect match between fast real-time machine control and data plant management.
In addition, today’s development teams are often spread around the world, and increasingly solutions developed for one factory need to be duplicated at different locations, each with its own specific set of requirements, standards and local regulations. Managing code across different teams and locations can be a sizable challenge. Therefore, these IDE systems also need to include tools to manage code versioning to allow for collaborative development and operation.
Sysmac Studio integrates configuration, programming, simulation, and monitoring in a simple interface that allows engineers to manage vision, motion, control, safety, and robotics in one control system within the platform’s rich interface. It allows multiple co-developers to work on the same project, with easy project comparison and efficient handling of machine versions.
Omron has chosen Git, which is the most popular open-source distributed control system, giving development teams the freedom to choose any Git-based cloud web repository. The version control system allows engineers to work on a local version of a project with full control over the project source code. Improvements and modifications made to the code on the local version can then be merged with a remote server, so other teams can access the code system.
Omron can provide most slave devices on the Ethernet network. The setup and configuration are done through just one connection to the master controller.
Introduction to Part 2 loop signatures and process transfer functions
Fieldbus & Industrial Networking
The previous series of loop signature articles dealt with the basics of control loop optimisation, and concentrated on troubleshooting and ‘SWAG’ tuning of simple processes. In this new series, consideration will be given to dealing practically with more difficult issues like interactive processes, and with processes with much more complex dynamics.
