Important User Information

Solid state equipment has operational characteristics differing from those of

electromechanical equipment. Safety Guidelines for the Application,

Installation and Maintenance of Solid State Controls (publication SGI-1.1

available from your local Rockwell Automation sales office or online at

http://literature.rockwellautomation.com

) describes some important

differences between solid state equipment and hard-wired electromechanical

devices. Because of this difference, and also because of the wide variety of

uses for solid state equipment, all persons responsible for applying this

equipment must satisfy themselves that each intended application of this

equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for

indirect or consequential damages resulting from the use or application of

this equipment.

The examples and diagrams in this manual are included solely for illustrative

purposes. Because of the many variables and requirements associated with

any particular installation, Rockwell Automation, Inc. cannot assume

responsibility or liability for actual use based on the examples and diagrams.

Firmware Revision

History

Features are added to the controllers through firmware upgrades. See the

latest release notes, 1763-RN003

, to be sure that your controller’s firmware

is at the level you need. Firmware upgrades are not required, except to

allow you access to the new features. See “Firmware Upgrades” below.

Firmware Upgrades

Enhanced features are added to the controllers through a firmware

upgrade. This firmware upgrade is not required, except to allow you

access to the latest features. To use the newest features, be sure your

controller’s firmware is at the following level:

To upgrade the firmware for a MicroLogix controller visit the MicroLogix

web site at http://www.ab.com/micrologix

.

To use all of the latest features, RSLogix 500 programming software must

be version 7.20.00 or higher.

I/O Configuration

This section discusses the various aspects of Input and Output features of

the MicroLogix 1100 controllers. Each controller comes with a certain

amount of embedded I/O, which is physically located on the controller.

The controller also allows for adding expansion I/O.

This section discusses the following I/O functions:

• Embedded I/O on page 13

• MicroLogix 1100 Expansion I/O on page 15

• MicroLogix 1100 Expansion I/O Memory Mapping on page 16

• I/O Addressing on page 24

• I/O Forcing on page 25

• Input Filtering on page 25

• Latching Inputs on page 28

Embedded I/O

The MicroLogix 1100 provide discrete I/O and analog input that is built

into the controller as listed in the following table. These I/O points are

referred to as Embedded I/O.

14 I/O Configuration

AC embedded inputs have fixed input filters. DC embedded inputs have

configurable input filters for a number of special functions that can be

used in your application. These are: high-speed counting, event input

interrupts, and latching inputs. The 1763-L16BBB has two high-speed

outputs for use as pulse train output (PTO) and/or pulse width

modulation (PWM) outputs.

I/O Configuration 15

MicroLogix 1100

Expansion I/O

If the application requires more I/O than the controller provides, you can

attach I/O modules. These additional modules are called expansion I/O.

Expansion I/O Modules

For the MicroLogix 1100, Bulletin 1762 expansion I/O is used to provide

discrete and analog inputs and outputs, and specialty modules. You can

attach up to four expansion I/O modules in any combination.

Addressing Expansion I/O Slots

The figure below shows the addressing for the MicroLogix 1100 and its

I/O.

The expansion I/O is addressed as slots 1 through 4 (the controller’s

embedded I/O is addressed as slot 0). Modules are counted from left to

right as shown below.

TIP

In most cases, you can use the following address format:

X:s/b (X = file type letter, s = slot number, b = bit

number)

See I/O Addressing on page 24 for complete information

on address formats.

error (over- or under-range) exists for that channel, or there is a

general module hardware error.

20 I/O Configuration

• Ox = Over-range flag bits for channels 0 through 3. These bits are set when the

input signal is above the user-specified range. The module continues to

convert data to the maximum full range value during an over-range condition.

The bits reset when the over-range condition clears.

• UIx = Under-range flag bits for input channels 0 through 3. These bits are set

when the input signal is below the user-specified range. The module continues

to convert data to the maximum full range value during an under-range

condition. The bits reset when the under-range condition clears.

• SGNx = The sign bit for channels 0 through 3.

1762-OF4 Input Data File

For each module, slot x, words 0 and 1 contain the analog output module

status data for use in the control program.

The bits are defined as follows:

• SOx = General status bits for output channels 0 through 3. This bit is

set when an error (over- or under-range) exists for that channel, or

there is a general module hardware error.

• OOx = Over-range flag bits for output channels 0 through 3. These

bits indicate an input signal above the user range and can be used

in the control program for error detection. The module continues to

convert analog data to the maximum full range value while this bit is

set (1). The bit is reset (0) when the error clears.

• UOx = Under-range flag bits for output channels 0 through 3. These

bits indicate an input signal below the user range. They can be used

in the control program for error detection. The module continues to

convert analog data to the minimum full range value while this bit is

set (1). The bit is reset (0) when the error clears.
