The basis of the FCS system is a digital intelligent field device.

The digital intelligent field device is the hardware support and foundation of the FCS system. The reason is very simple. The

FCS system implements the two-way digital communication field bus signal system between the automatic control device

and the field device. 

If the field device does not follow the unified bus protocol, that is, the relevant communication protocol, and does not have

the function of digital communication, then the so-called two-way digital communication is just an empty talk, and it

cannot be called a field bus control system. 

Another point, a major feature of the field bus is to increase the field level of control functions.[Allen Bradley 1756-A10 10 Slots Chassis, Allen Bradley 1747-L541 SLC 500 Controller, Siemens 6ES7414-4HM14-0AB0 SIMATIC S7-400H CPU, B&R X20BB81 Bus Module] If the field device is not a multi-functional intelligent product, then the haracteristics of the control system of

the field bus will not exist, and the advantages of the so-called simplified system, convenient design, and convenient

maintenance are also virtual.
