Checking for
Instrument Errors
The following BASIC program is a method of checking for errors as you
program the instruments (plug-in modules) in your VXIbus system. The
program monitors the instrument’s Standard Event Status Register for error
conditions. If no errors occur, the instrument functions as programmed. If
errors are detected, the instrument interrupts the controller. The controller
reads the error codes and messages from the instrument’s error queue and
displays them. In this program, the instrument (multimeter) at secondary
GPIB address 03 (logical address 24) is monitored. The controller
commands used are for an HP Series 300 controller (external or an
embedded controller) running the BASIC language.
NOTE If an RS-232 display terminal is used, typing:
SYST:ERR?
at the VOLTMTR_24: prompt reads and displays the error messages from
the multimeter’s error queue.
