Digital I/O Module Operation in a Logix 5000 Control System Chapter 1
The owner-controller monitors its connection with a module. Any break in the
connection, for example, the loss of power to a remote FLEX 5000 I/O system,
causes a fault. The Logix Designer application monitors the fault status tags to
indicate when a fault occurs on a module.
‘Configured By’ Options for Safety I/O Modules
The ‘Configured By’ choice determines what data is exchanged between the
owner-controller and the module. This is an example Module Definition dialog
box, and available Connection choices, for FLEX 5000 I/O safety modules.
Tab le 7
describes the connection types that you can use with FLEX 5000 I/O
safety modules.

Configured by Choice Description
FLEX 5000 Safety Input Module FLEX 5000 Safety Output Module
This controller The module returns the following to the owner-
controller:
• General fault data
• Safety input data
The module exchanges the following with the owner-
controller:
• General fault data
• Safety input data
• Safety output data
External means When the External Means option is chosen, another controller owns the module.
A controller that chosen this option does not write configuration for the module. It merely listens to the data
exchanged with the owner-controller. That is, it receives Safety input data.
