Table 3-1. Bit Configurations of Status Registers (continued)
Questionable Status Group
Same as Channel Status Group
Standard Event Status Group
Operation Complete. The load has completed all pending operations. *OPC must be
0 OPC
programmed for this bit to be set when pending operations are complete.
Query Error. The output queue was read with no data present or the data was lost. Errors
2 QYE
in the range of −499 through −400 can set this bit.
Device-Dependent Error. Memory was lost or self test failed. Errors in the range of −399
3 DDE
through −300 can set this bit.
Execution Error. A command parameter was outside its legal range, inconsistent with the
4 EXE
load's operation, or prevented from executing because of an operating condition. Errors
in the range of −299 through −200 can set this bit.
Command Error. A syntax or semantic error has occurred or the load received a <get>
5 CME
within a program message. Errors in the range of −199 through −100 can set this bit.
Power-On. The unit has been turned off and then on since this bit was last read.
7 PON
Status Byte and Service Request Enable Registers
2 CSUM Channel Summary. Indicates if an enabled channel event has occurred.
3 QUES Questionable Status Summary. Indicates if an enabled questionable event has occurred.
4 MAV Message Available Summary. Indicates if the Output Queue contains data.
5 ESB Event Status Summary. Indicates if an enabled standard event has occurred.
6 MSS Master Status Summary. For an *STB? query, MSS is returned without being cleared.
RQS
