Using Advanced fieldbus resources.

Fieldbus is an enabling technology that is changing -- in fact revolutionising -- the way users design, install, configure, and operate control systems.

Fieldbus offers a number of potential changes from current analogue signal transmission. These can be summarised as follows:

* The ability to connect multiple field devices to a single bus segment;

* The ability to transmit diagnostic information from the field device to a central host system; and

* The ability to migrate control algorithms from a central host system into the field dev
