status.condition
Attribute Status byte register.
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage Reads the status byte register:
statbyte = status.condition
Remarks • This attribute is used to read the status byte, which is returned as a numeric value. The binary
equivalent of the returned value indicates which register bits are set. The least significant bit of
the binary number is bit 0, and the most significant bit is bit 7.
• For example, assume value 129 is returned for the condition register. The binary equivalent is
10000001. This value indicates that bit B0 (MSB) and bit B7 (OSB) are set.
• The bits of the status byte register are described as follows:
• Bit B0, Measurement Summary Bit (MSB): Set summary bit indicates that an enabled
measurement event has occurred.
• Bit B1, System Summary Bit (SSB): Set summary bit indicates that an enabled system
event has occurred.
• Bit B2, Error Available (EAV): Set summary bit indicates that an error or status message is
present in the Error Queue.
• Bit B3, Questionable Summary Bit (QSB): Set summary bit indicates that an enabled
questionable event has occurred.
• Bit B4, Message Available (MAV): Set summary bit indicates that a response message is
present in the Output Queue.
• Bit B5, Event Summary Bit (ESB): Set summary bit indicates that an enabled standard
event has occurred.
• Bit B6, Request Service (RQS)/Master Summary Status (MSS): Set bit indicates that an
enabled summary bit of the Status Byte Register is set. Depending on how it is used, Bit B6
of the Status Byte Register is either the Request for Service (RQS) bit or the Master
Summary Status (MSS) bit:
- When using the GPIB or VXI-11 serial poll sequence of the SourceMeter instrument to
obtain the status byte (serial poll byte), B6 is the RQS bit.
- When using status.condition or the *STB? common command to read the status byte,
B6 is the MSS bit.
• Bit B7, Operation Summary (OSB): Set summary bit indicates that an enabled operation
event has occurred.
Details See Status byte and service request (SRQ) in Appendix C.
Example Reads the status byte:
statbyte = status.condition
print(statbyte)
Output: 1.29000e+02
The above output indicates that bits B0 (MSS) and B7 (OSB) are set.
