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.
