3. Fieldbus Integration With Experion System
3.2. Control Integration
Type creation makes integration possible
The fieldbus device Type function included with Control Builder makes integrating
fieldbus function blocks with Control Builder ones possible. The Type function reads the
manufacturer's DD for the fieldbus device and creates a device block type that is stored in
the Control Builder Library tab. The device block type includes the device's fieldbus
function blocks, so it can be configured and integrated with control strategies through
Control Builder.
Fieldbus device Analog Input integration
A user can functionally "wire" the output from an Analog Input (AI) function block in a
fieldbus device residing on an H1 link to the input of a regulatory control type function
block contained in a Control Module in the Experion Control Builder application. The
Proportional, Integral, Derivative (PID) function block is a typical regulatory control type
function block.
The following simplified functional diagram shows how the output from an Analog Input
function block in a fieldbus compliant transmitter is integrated with a PID function block
in a Control Module that is assigned and loaded to the CEE in the Control Processor
Module (CPM).
