Questionable Status Group
Register Functions
The Questionable Status registers record signals that indicate abnormal operation of the power module. As shown in Figure
4-1, the group consists of the same type of registers as the Status Operation group. The outputs of the Questionable Status
group are logically-ORed into the QUES(tionable) summary bit (3) of the Status Byte register.
Register Commands
Programming for this group is derived from the STAT:QUES commands described in "Chapter 3 - Language Dictionary"
and summarized in Table 4-3.
