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.
Tab le 6
describes the connection types that you can use with FLEX 5000 I/O
modules.
IMPORTANT You can change the RPI while the project is online. If you change the RPI
while the project is online, however, the connection to the module is closed
and reopened in one of the following ways:
• You inhibit the connection to the module, change the RPI value, and
uninhibit the connection.
• You change the RPI value. In this case, the connection is closed and
reopened immediately after you apply the change to the module
configuration.

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.
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.
