This paper reviews current and proposed fieldbus standards that affect Europe. Relevant technologies and the formation of standards are shown. The initial goal of a single global standard and the recognition of a number of emerging de facto standards are discussed, as is the potential future standardisation of fieldbus technology.

The traditional use of fieldbus is discussed. Examples of novel applications enabled by fieldbus are introduced. Work on temporary fieldbus connectivity that allows more robust and simple tool change mechanisms is then described.

Availability, reliability, flexibility and comprehensive diagnostics are the most significant demands placed upon safety systems today. Increasing payloads, work ranges and cycle times of robotic processes necessitate a different approach to safety, particularly other than that offered by conventional safety relays and fencing. The development of fieldbus for safety‐related applications and new International and European Standards have fundamentally changed the manner in which safety is now being engineered in the plant. BMW are the first to directly integrate robotic safety functions using a safety‐related fieldbus.

Standards have restricted the use of networks and programmable electronics in safety‐related applications. New standards have released technology to enable improvements in safety and ensure developments take place within an overall safety framework. Best practice in the additional protocol enhancements required is discussed. The installation of a safety‐related fieldbus, replacing conventional hardwiring in a machine safety system is used to illustrate the potential of the technology. The use of fieldbus in safety‐related applications is shown to reduce complexity and enhance functionality, whilst enabling significantly reduced ownership cost.

Fieldbus has been used to control self drill drive screw (SDDS), spot clinching and self pierce riveting tools mounted to a single robot with a tool changer. This has reduced wiring complexity and enabled more robust cable dressing. The network, tool operation and tool changer are described.
