VIEWING DIAGNOSTIC DATA
3.4.1 Reading Diagnostics
Commands are typed on the command line near the bottom of the status display (Figures 3-
3, 3-4 and 3-17) and sent to the instrument by clicking on the ENTER button or pressing the
enter key. The command for reading diagnostics is:
R DIAGS type
When typing this command, the letter R and the abbreviation DIAGS must be followed by a
space. Upon entry of this command, the screen displays up to 15 diagnostics of the specified
type and a prompt to continue appears if necessary. The specified types may be:
AB Read abnormal diagnostics - Return points that are active or
unacknowledged (default if type is not specified)
ABQ Read abnormal or quality - Return points that are active,
unacknowledged, or have bad status qualities
UAK Read unacknowledged - Return points that are unacknowledged
UAKQ Read unacknowledged or quality - Return points that are
unacknowledged or have bad unacknowledged status quality
ACT Read active - Return points that are active
ACTQ Read active or quality - Return points that are active or have bad
active status quality
SUP Read suppressed - Return points that are suppressed
ALL Read all points - Return all diagnostic points
Active Diagnostics
An effective way to quickly check for active diagnostics is to use the R DIAGS command
without specifying a type. This returns all points that are active or unacknowledged.
An example of the message returned in response to an R DIAGS command is:
WRIM1 NEW/CLR UAK G ACT G
8 WRIM MODULE ERROR
This message, as it appears on the status display, is shown in the next figures for Application
Builder. The information contained is as follows:
• Block Type and Occurrence Number - This identifies the block reporting the
diagnostic (WRIM1 in the example).
• Classification of the diagnostic:
o NEW/CLR - Diagnostics having a sustained active state, which is cleared
when normal conditions are restored.
o ACK ONLY - Diagnostics resulting from a momentary occurrence where the
abnormal condition is not sustained. This class is sometimes accompanied
by a counter attribute, which counts the number of occurrences.
• Status - The diagnostic status at the time the read command is received (UAK G
ACT G in the example). This status data indicates that the diagnostic is
unacknowledged (UAK), unacknowledged attribute quality is good (G), diagnostic
condition is active (ACT), and active status quality is good (G). After
acknowledgement, the status changes to ACK G ACT G.
