Configuration Description

8.1 Introduction

About This Section
This section provides information about the construction and contents of the Logix 3400IQ digital
positioner Function Block Application Process (FBAP) — the application that defines Logix 3400IQ
digital positioner function and operation in the process application.) This information provides some
understanding of the elements that make up the configuration of the device application.
For More Information on FBAP
The FBAP elements are described as they apply to the Logix 3400IQ digital positioner in the following
sections. More detailed information can be found in Fieldbus Foundation documents FF-890 and
FF-891 Foundation Specification Function Block Application Process (Parts 1 and 2).
8.2 Function Block Application Process
Introduction
The FBAP comprises a set of elementary functions which are modeled as function blocks. Function
blocks provide a general structure for defining different types of device functions (such as analog
inputs, analog outputs and PID control).
The FBAP also contains other objects that provide other device functions, such as furnishing alarm
information, historical data and links to other blocks for transferring data.
FBAP Elements
The key elements of the FBAP are:
• Logix block objects and their parameters (and consist of the following block types)
• Resource block
• Transducer block
• PID Function block
• AO Function block
• Link Objects
• Alert Objects
• Trend Objects
• View Objects
• Domain Objects
