(IEC 61158-2) designed for use in the process industry and also complies with the ISA-SP50
recommendation for fieldbus devices.
The major benefits in adopting this standard include:
•

•
This last item is one of the advantages of F
and Device Descriptions to implement control strategy. Function Blocks are standardized automation
functions with defined behaviour used to represent different type of functions, such as discrete input
(DI), discrete output (DO), analog input (AI), analog output (AO), Proportional / Integral / Derivative
(PID), etc.
Furthermore, every F
Once the hardware of a F
configure the transducer block parameters. The desired transducer functionality is associated with a
specific function block via a Channel.
The host system is used to link the function blocks together to create a control application that can
be downloaded to the devices in the segment.

Fieldbus is an open networking standard which provides an open specification for both the
Fieldbus communication protocol is an industry proven international standard
Multi-drop capability with up to 32 devices per segment;
Extended trunk length using repeaters which increase the total bus length and the number
of devices in the network;
Power and communications over the same shielded twisted pair network that allow to know
the physical status of XTE3000 actuator even if it is without actuator mains power;
Distribution of the control into the field devices reducing the amount of control equipment
in the plant.
Fieldbus device has a Resource Block and at least a Transducer Block.
