Module Tags Appendix A
Ixx.DiagnosticSequenceCount SINT Increments for each time a distinct diagnostic condition is detected,
and when a distinct diagnostic condition transitions from detected
to not detected.
Set to zero by product reset or power cycle. Wraps from 255 (-1) to 1
skipping zero.
-128…127
The value of 0 is skipped except during
module power-up.
Ixx.Fault BOOL Indicates that channel data is inaccurate and cannot be trusted for
use in the application.
• 0 = Good
• 1 = Bad, causing fault
If the tag is set to 1, you must
troubleshoot the module to correct the
cause of the inaccuracy.
IMPORTANT: Once the condition that
causes the tag to change to 1 is
removed, the tag automatically resets to
0.
Ixx.Uncertain BOOL Indicates that the channel data can be inaccurate but the degree of
inaccuracy is not known.
• 0 = Good data
• 1 = Uncertain data
If the tag is set to 1, you must
troubleshoot the module to correct the
cause of the inaccuracy.
IMPORTANT: Once the condition that
causes the tag to change to 1 is
removed, the tag automatically resets to
0.
Ixx.LastExecutedCommand SINT Indicates the number of the latest executed command, and the
Update Counter indicates the status for command level. If this value
is updated, either a new command is executed, not changed,
command is not executed, or have not finished yet.
• -1(value shown prior to any command)
•0…49
Ixx.Command.yy.Fault BOOL Indicates that channel data is inaccurate and cannot be trusted for
use in the application.
The number of Commandyy tags (where yy can be 0…49) are
dynamically created depending on the command list you create.
• 0 = Good
• 1 = Bad, causing fault
If the tag is set to 1, you must
troubleshoot the module to correct the
cause of the inaccuracy.
IMPORTANT: Once the condition that
causes the tag to change to 1 is
removed, the tag automatically resets to
0.
Ixx.Command.yy.Uncertain BOOL Indicates that the channel data can be inaccurate but the degree of
inaccuracy is not known.
• 0 = Good data
• 1 = Uncertain data
If the tag is set to 1, you must
troubleshoot the module to correct the
cause of the inaccuracy.
IMPORTANT: Once the condition that
causes the tag to change to 1 is
removed, the tag automatically resets to
0.
Ixx.Command.yy.ParityError BOOL Status that shows whether a parity error has occurred or not. • 0 = Non-occurrence
•1 = Occurrence
Ixx.Command.yy.ResponseTimeout BOOL Shows if there was a response timeout. • 0 = Non-occurrence
•1 = Occurrence
Ixx.Command.yy.FramingError BOOL Shows if there was a framing error. • 0 = Non-occurrence
•1 = Occurrence
Ixx.C
ommand.yy.BufferOverRun BOOL Shows if a buffer overrun has occurred. • 0 = Non-occurrence
•1 = Occurrence
