The essence of the FCS system is the on-site information processing.

For a control system, whether DCS or field bus is used, the system needs to process at least the same amount of

information. In fact, after using field bus, more information can be obtained from the field. The amount of

information in the field bus system has not decreased, or even increased, while the cables for transmitting information

have been greatly reduced. 

This requires on the one hand to greatly improve the ability of the cable to

transmit information, on the other hand to allow a large amount of information to be processed on-site to reduce

the round-trip of information between the site and the control room. It can be said that the essence of fieldbus is

the fieldization of information processing. [B&R X20AO4622 Analog Output Module, Allen Bradley 1746-A4 4 Slots

Reducing information round trips is an important principle in network design and system configuration. Reducing

information roundtrips often has the benefit of improving system response times. therefore. When designing the

network, nodes with a large amount of information exchanged between each other should be placed in the same

branch.
