Since the 1990s, the increasing deployments of networked automation systems led to increased manufacturing productivity, improved interchangeability of devices from different vendors, facilitated flexibility and reconfigurability for various applications and improved reliability, while reducing installation and maintenance costs. However, the reliability of a network has great impact on the rel...

1 Introduction The traditional communication architecture for control systems is point-to-point, which has been successfully implemented in industry for decades. However, expanding physical setups and functionality push the limits of the point-to-point architecture. Hence, a traditional centralized point-to-point control system is no longer suitable to meet new requirements , such as modularity...

Network technology is being used more and more to replace direct-wired links to integrate equipment components of automated and semi-automated welding systems. The standardization of device-level network technology, and the gradual appearance of network capable welding devices, means that users and integrators are facing the challenge of using networks for the first time, or of choosing one amo...

Since the 1980s, the manufacturing environment has seen the introduction of numerous sensor/actuator bus and network protocols for automation systems, which led to increased manufacturing productivity, improved interchangeability of devices from different vendors, facilitated flexibility and reconfigurability for various applications and improved reliability, while reducing installation and mai...

Originally designed for carrying the increasing amount of data exchanged in modern cars, the CAN (Controller Area Network) protocol is today adopted in a wide range of automated manufacturing environments. CAN only covers physical and data link layer protocol, that's why several application layers like DeviceNet or CANopen have been developed in order to standardize communication between nodes ...

In this article, new techniques and technologies have been tried and tested in the installation and commissioning of Roller Home industrial robots, in order to produce a Tiba car with a focus on cost reduction. Due to the fact that press equipment for automobile parts requires a lot of expenses, it was decided to use robots with the same function of roller to reduce costs and increase the q...

Contrary to initial persuasion, up to now there is no standard fieldbus but almost 50 different systems with deterministic characteristics regarding technical functions, application and popularity. But not every bus fits industrial use (fig. 1). Fig. 1: Encoder installed at a straightening machine in a sheet metal processing application. Multiturn absolute encoders with modular bus covers for c...

Various communication protocols are used within a typical industrial facility including Modbus RTU, DeviceNet and Profibus. These protocols used over the years have been in a Master-Slave configuration. Intelligent Electronic Devices (IEDs) are slaves to single or multiple masters with one-way communication with the IED acting as a data/controlled node to the master device. Control is implement...

This paper describes the adoption of the Ethernet/IP standard in the development of a specification for the interconnection of mining equipment as part of an industry-sponsored Landmark longwall automation project. Longwall mining is used extensively worldwide and accounts for the majority of underground coal production in Australia and the USA. Full automation of the longwall mining process is...
