6.1.2 Retrieving Diagnostic Data
Table 6-2 also lists the diagnostic query commands associated with each of the diagnostic codes. When a diagnos-
tic code is generated, the related query command can be used to retrieve additional information about the error.
Using the query command for a given error also clears the diagnostic flag for that error. Once cleared, that data
is no longer available.
6.2 Diagnostic Commands
Table 6-3 summarizes the diagnostic commands available for the iQUBE 2 , including query commands, parameter-
setting commands, and the values that can be assigned by the parameter-setting commands. The diagnostic com-
mands are described in detail in the following sections.
6.2.1 System Diagnostic Commands
System diagnostic commands consist of query commands only; there are no parameter-setting commands. System
diagnostics are always enabled.
For data formats that include the <S> status token, some system diagnostic errors also set the status to I
(invalid).
Power Supply Error, <D> = P
The power supply diagnostic flag is set when any CPU board in the system has a power supply fault (input voltage
less than 6 VDC or greater than 12 VDC).
