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.

Chapter 1
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.

• 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.
