Digital I/O Module Operation in a Logix 5000 Control System Chapter 1
Connection Types Available with FLEX 5000 Standard I/O Modules
When configuring a FLEX 5000 standard I/O module, you must define the
module. Connection is a required parameter in the Module Definition. The
choice determines what data is exchanged between the owner-controller and the
module.
Tabl e 6
describes the connection types that you can use with FLEX 5000 I/O
modules.

Description
FLEX 5000 Input Modules FLEX 5000 Output Modules
Data The module returns the following to the
owner-controller:
• General fault data
•Input data
The module returns the following to the
owner-controller:
• General fault data
• Output data
Data with Events
(1)
(1) Data with Events and Listen Only Data with Events are available only on the 5094-IB16 digital input module.
Data Types Available with FLEX 5000 Standard I/O Modules
The Module Definition includes a Data parameter that matches the module type.
Digital input modules use Input Data, and digital output modules use Output
Data.
The module type and Connection choice determine the available Input Data or
Output Data choices. For example, you can configure a 5094-IB16 digital input
module to use the Connection choice Data with Events. The resulting Input Data
choices are Data with Events include Data, Packed Data, or Timestamped Data.
For more information on the Connection and Data parameter choices available
with FLEX 5000 I/O modules, see the Logix Designer application.
The module returns the following to the
owner-controller:
• Event fault data
• Event input data
•Event output data
N/A
Listen Only Data
Listen Only Data
with Events
(1)
When a Listen Only Data connection is used, another controller owns the module.
A controller that makes a Listen Only Data connection to the module does not write
configuration for the module. It merely listens to the data exchanged with the owner-
controller.
Use Listen Only Data when the connection type is set to Data. Use Listen Only Data with
Events when the connection type is set to Data with Events.
IMPORTANT: If a controller uses a Listen Only Data connection, the connection must use the
Multicast option.
For more information on Listen Only connections, see Listen Only Mode
on page 35. In this
case, all other connections to the module, for example, the connection to the owner-
controller must also use the Multicast option.
