Digital Module Operation in a Control System
Chapter 1
Input Module Operation
Logix 5000 controllers do not poll the Compact 5000 I/O standard or safety
input modules for input data.
The data exchange process between the input modules and the controller
differs based on whether the module is a local I/O module or remote I/O
module.
Local Compact 5000 I/O Digital Input Modules
Local Compact 5000 I/O digital input modules broadcast their input data,
that is, channel and status data, to the system backplane at the time that is
defined in the RPI.
At the RPI, the following events occur.
1. The local input module scans its channels for input data.
2. The module sends the data to the system backplane.
3. The controller receives the data immediately.
Trigger Events for Standard Input Modules
Some Compact 5000 I/O standard input modules can trigger an event. For
example, the modules can trigger the Event task. The event task lets you
execute a section of logic immediately when an event, or receipt of new data,
occurs.
The following can trigger events:
• An input state change.
• A counting input done bit change.
• A pattern of input state changes on multiple module inputs.
For more information on how to use a Compact 5000 I/O standard input
module to trigger an event, see
