About Module Diagnostics
All status and diagnostic information (strobed, polled, cyclic, or
change-of-state) is reported back over the network communication adapter.
A single point of failure is detected and reported at the module and to the
control system.

• Module Status indicator
indicates the health of the
module.
• Network Status indicator
indicates the status of the
communication link.
• DeviceLogix indicator
indicates the state of the
DeviceLogix program.
• I/O point indicator
