•
Bit 3 (device dependent error) is set by the switch to indicate that
an error has occurred that is not a command error, an execution
error, or a query error.
•
Bit 4 (execution error) is set when an execution error is detected by
the switch, for example, if a command parameter is out of the range
of the switch or a valid program message cannot be executed due to
some condition in the switch.
•
Bit 5 (command error) is set when a command error is detected by
the switch, for example, if a syntax error is detected in a program
message, an incorrect command header is received, or if an IEEE
GET message is received in the middle of a program message.
•
Bit 6 (user request) is always set to 0.
•
Bit 7 (power on) is set when an off-‐to-‐on transition occurs in the
power supply of the switch.
Standard Event Status Enable Register
The contents of the standard event status enable register determine
which events in the standard event status register are reflected in the
event summary bit (ESB) of the status byte register.
Operation and Questionable Condition Registers
Each bit in these condition registers reflects a specific condition or state
within the switch. A bit is set when the switch enters the state
associated with that bit and remains set while the device is in that state.
