The Diagnostics screen displays real-time results of system diagnostics including:
• CPU: Detailed information about PLC CPU diagnostics.
• CPU Major Fault: Details about the last or current CPU Major Fault. If the Major Fault Active
text is not bright red, then there is no major fault active.
• Heartbeats: Information about the bidirectional heartbeats between the PLC and HMI. The
length of the trend showing the heartbeat signal can be adjusted from this screen to view a
longer-term period.
• HMI Diagnostics: Displays performance and status information about the software
components for the HMI. All items should either be On Scan or Connected.
Clicking on the names of the components will display a detailed faceplate with diagnostics
and engineering functions. All users can view the faceplate, only users with engineering-level
security can execute functions.
• Indicators: The current status of miscellaneous indicators for the system that don’t fit on the
process screen. Note that the instruments and layout of this section of the Diagnostics
Screen may not represent your installed system as some functions may not be available.
