About Fieldbus
Outline
Fieldbus is a bi-directional digital communication protocol for field devices, which offers an
advancement in implementation technologies for process control systems and is widely
employed by numerous field devices.
FVP110 employs the specification standardized by The Fieldbus Foundation, and provides
interoperability between GE Masoneilan devices and those produced by other
manufacturers.
Fieldbus comes with software consisting of AO function block, two DI function blocks and
optional PID function block, providing the means to implement a flexible instrumentation
system.
For information on other features, engineering, design, construction work, startup and
maintenance of Fieldbus, refer to
Fieldbus Technical Information
(TI 38K3A01-01E).
Internal Structure of FVP110
The FVP110 contains two virtual field devices (VFD) that share the following functions.
System/
network
Managem
ent VFD
❑
Sets node addresses and Physical Device tags (PD Tag) necessary
for communication.
❑
Controls the execution of function blocks.
❑
Manages operation parameters and communication resources (Virtual
Communication Relationship: VCR).
Function
Block VFD
❑
Resource block - Manages the information common to each FB VFD
in FVP110.
❑
Transducer block - Located between Hardware I/O (actuator, sensor)
and AO/DI function blocks; passes the control signal from AO function
block to I/P module to control the valve position.
❑
AO function block - Accepts a:
