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
