Summary

Chapter 1 Communicate with I/O Modules

Introduction to I/O Modules

Describes the process of adding I/O modules to a controller's I/O configuration.

Requested Packet Interval (RPI)

Defines the RPI and its role in controlling I/O data update frequency between devices.

Communication Format and Ownership

Explains data structures determined by communication format and controller-module relationships.

Electronic Keying

Enables automatic comparison of physical modules to configured settings to prevent communication errors.

Addressing I/O Data

Details the standard format for addressing I/O data points using tags and their components.

Buffer I/O

Explains the technique of using copied I/O data to prevent scan-time value changes in logic.

Chapter 2 Organizing Tags

Introduction to Tags

Explains the use of alphanumeric tag names for addressing variables and data within a controller.

Data Types

Defines various data types available for tags, such as integers, real numbers, and strings.

Scope

Differentiates between controller-scoped (global) and program-scoped (local) tags and their accessibility.

Create a Tag

Provides step-by-step instructions for creating and editing tags using the Logix Designer Tag Editor.

User-Defined Data Types

Explains the creation of custom data structures (UDTs) to organize complex data related to machinery.

Chapter 3 Force I/O

Introduction to Forcing

Describes using forces to override logic for debugging, testing, or temporary process control.

Forcing Precautions

Highlights critical safety considerations and potential risks when using forces in automation logic.

Enable Forces

Explains the process of enabling I/O and SFC forces at the controller level for active operation.

Disable or Remove a Force

Details the methods for disabling or removing active forces to return logic to normal operation.

Forcing Values

Explains how to force specific input or output tag values, overriding normal logic execution.

Chapter 4 Data Access Control

Introduction to Data Access Control

Introduces tag attributes that control how external applications access and modify tag data.

Configure External Access

Details how to set external access attributes (Read/Write, Read Only, None) for tags.

Constant Value Tags

Explains designating tags as constants to protect their values from programmatic modification.

Configure Constant Tags

Provides steps for setting the constant attribute for tags via dialog boxes or the Tag Editor.
