slot[X].thermal.state
Remarks
This attribute will not exist for a slot if a card is not installed or the card installed does
not support thermal state detection. In these cases, the return value will be nil. Use
this attribute to query the thermal state only if the card supports detecting thermal
state.
Example
To query the thermal state on Slot 3:
print(slot[3].thermal.state)
status functions and attributes
The following provides a brief overview of the status model. For details, see
Status Model (on page 12-1).
Status byte and SRQ
The status byte register receives the summary bits of the five status register
sets, a master summary bit, and two queues. The register sets and queues
monitor the various instrument events. When an enabled event occurs, it sets a
summary bit in the status byte register. When a summary bit of the status byte is
set and its corresponding enable bit is set (as programmed by the user), the
RQS/MSS bit will set to indicate that an SRQ has occurred, and the GPIB SRQ
line will be asserted.
