The View Diags Sub-Menu displays up to 14 System Diagnostics, all of which are not editable.
The Net Errors, Network State, Network ID and Dup Net ID System Diagnostics only appear for
XLE/XLT models that have CAN ports (XE1xx).
The first five System Diagnostics are critical. If any of them indicate a Fault condition, the XLE/XLT will
not enter or remain in Run mode, and the problem must be investigated and corrected.
System Ram: Ok = System RAM power-up self-test passed
Fault = System RAM power-up self-test failed
System BIOS: Ok = System BIOS power-up self-test passed
Fault = System BIOS power-up self-test failed
Firmware: Ok = Firmware power-up self-test passed
Fault = Firmware power-up self-test failed
Logic Error: Ok = All executed ladder instructions are legal for loaded firmware
Fault = A ladder instruction not supported by firmware was found
User Program: Ok = Ladder program and I/O configuration loaded successfully
Fault = Ladder program or I/O configuration not loaded or load failed
The last nine System Diagnostics are informational. If any of them indicate a Warning condition,
the XLE/XLT can still enter and remain in Run mode, but the problem should be investigated
and corrected.

W-Dog Trips: 0 = Watchdog timer has not tripped since the last power-up
x = Number of times watchdog timer has tripped
Net Errors: 0 = No CAN network bus-off errors have occurred
x = Number of CAN network bus-off errors that have occurred
Network State: Ok = At least one other node was found on the CAN network
Warning = No other nodes were found on the CAN network
Network ID: Ok = This node’s CAN Network ID is in the range 1 to 253
Warning = This node’s CAN Network ID was out of range at power-up
Dup Net ID: Ok = This node’s Network ID is unique on the CAN network
Warning = This node’s Network ID is duplicated in another node
Clock Error: Ok = Time and date have been set
Warning = Time and date need to be set
