Diagnostics Chapter 15
Choose Online or Offline Diagnostics
When you start the diagnostics window, Diag. Online is automatically
activated. This signals that you want all diagnostics data transferred
from the controller to the diagnostics buffer in RSLogix Guard PLUS!
software. As long as Diag. Online is active, new diagnostic data is
transferred to this buffer as it becomes available and if the filter you
selected applies.
Diag. Offline disconnects communication with the controller. This
ends the transmission of diagnostic data from the controller to the
diagnostics buffer in RSLogix Guard PLUS! software.
Filtering Diagnostic Data
Choose from these filters to determine what diagnostic data to display.

oldest entry.

newest entry.

Entries Per Diag. Determines the maximum number of entries to load into the buffer for the CPU and COM
diagnostics.
For example, if you enable short term and long term diagnostics for CPU and COM and you
set Entries Per Diag. = 10, the diagnostic window contains a maximum of 40 entries
(10 entries per diagnostic type).
RSLogix Guard PLUS! software can buffer as many as 5000 entries per type of diagnostic.
Sort If Sort is disabled, the diagnostic window displays entries in the order they were saved in
the controller.
If Sort is enabled, the diagnostic window automatically displays entries according to date.
