Experts in Fieldbus Systems & Components share their knowledge
The definition of a fieldbus is a means of communicating with input devices (sensors, switches) and output devices (valves, drives, indication lamps) without the need to connect each individual device to the controller (PLC, Industrial PC etc.). The obvious upshot is that a fieldbus can significantly reduce costs.
Fieldbus basics tutorial
Before fieldbus technology was introduced, computers would connect using direct serial connections, whereby only two devices could communicate per connection. The fieldbus allows hundreds of analogue and digital devices to connect to the controller via a single cable. This reduces the number of cables required in an installation, saving on installation time and installation cost.
There are many fieldbus devices and fieldbus modules available. Most fieldbuses are now ‘open’ to essentially ‘talk’ to the chosen control platform (e.g. PLC) and communicate via the fieldbus to specialist devices from a range of different manufacturers. There are a number of essential questions to consider before installing a fieldbus system find out more in this Fieldbus installation guide.
Cube67 is Murrelektronik’s award-winning, modular fieldbus system. It can communicate over most industrial communication protocols (fieldbus and industrial Ethernet) and can be customised to meet the specific requirements of an installation solution. Cube67 is characterised by its single cable technology, multi-function modules, flexible installation methods and robust, potted circuitry. The unique single cable module connection transfers both power and data from a single bus node to connected modules simplifying installation.
The IP67 rated MVK Metal fieldbus modules are an important component of machine and system installations. They replace complex parallel wiring, saving space in the cabinet. Due to its mechanical properties, MVK Metal is designed for applications in harsh industrial environments.
Murrelektronik's MVP12 Steel distribution box is made of high-quality stainless steel and, as such, is an ideal solution for a decentralised approach in Food and Beverage machines and installations. Routing cables while meeting hygienic requirements in Food and Beverage applications requires a lot of effort. However, with the MVP12 Steel distribution box, eight sensor cables are replaced by one homerun cable, significantly reducing installation time.
