For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set contents
(on
page E-1) and Enable and transition registers
(on page E-19). The individual bits of this register are defined in
the following table.
Bit Value Description
B0
status.operation.instrument.lan.CONNECTION
status.operation.instrument.lan.CON
Set bit indicates that the LAN cable
is connected and a link has been
detected.
Bit B0 decimal value: 1
B1
status.operation.instrument.lan.CONFIGURING
status.operation.instrument.lan.CONF
Set bit indicates the LAN is
performing its configuration
sequence.
Bit B1 decimal value: 2
B2-B9 Not used Not available
B10
status.operation.instrument.lan.TRIGGER_OVERRUN
status.operation.instrument.lan.TRGOVR
Set bit indicates one or more
enabled bits for the operation status
LAN trigger overrun register is set.
Bit B10 decimal value: 1,024
B11-B15 Not used Not applicable
As an example, to set bit B0 of the operation status LAN summary enable register, set
status.operation.instrument.lan.enable = status.operation.instrument.lan.CON.
In addition to the above constants, operationRegister can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set operationRegister to the sum of their decimal weights. For
example, to set bits B1 and B10, set operationRegister to 1,026 (which is the sum of 2 + 1024).
