Troubleshooting
About This Chapter
This chapter provides information about module diagnostics, and about
troubleshooting with the following indicators:
• Module status
• Network status
• DeviceLogix status
• Power indication
• I/O POINT status (ON/OFF/fault or diagnostic)
In addition, the following troubleshooting scenarios are provided:
• Peer connection is not working
• Configuration or DeviceLogix program cannot be downloaded to the
module
• Module’s DeviceLogix program exits the Run mode unexpectedly
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.
Node-level diagnostics:
• 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
indicates I/O (ON/OFF or
fault/diagnostic) status.
