Field I/O communication with Ethernet

31 March 2008

Most computer networks communicate on the basis of Ethernet technology. However, data in systems and machinery are transferred using many different fieldbus protocols. Communication between these systems and particularly with the computer networks is therefore complicated and can only be achieved using special software and hardware. The use of an Ethernet-based communication system in machinery (instead of the fieldbus systems) will help to solve this problem.

Ethernet does not just provide innovative technology but real added value as far as decentralisation is concerned, in the form of ‘Total Diagnosis.’ It is possible to monitor systems and localise problems from anywhere in the world, right down to individual ports. Faults such as open circuit, short circuit / overload, loss of supply etc. are relayed back and can even suggest replacement part numbers to the maintenance staff. Technicians can retrieve data or carry out pre-commissioning I/O checks using any Web browser via a Web server that is integrated in the bus node.

Cube67 has an array of configurable and modular digital and analogue I/O as well as modules for valve clusters, logic, temperature, counters and/or safe outputs. This does not just reduce the connecting time but also the number of components.
