A set bit indicates that the specified LAN trigger generated an action overrun when triggered to generate a trigger
packet.
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 Not used Not applicable
B1
status.operation.instrument.lan.trigger_overrun.LAN1
Bit B1 decimal value: 2
B2
status.operation.instrument.lan.trigger_overrun.LAN2
Bit B2 decimal value: 4
B3
status.operation.instrument.lan.trigger_overrun.LAN3
Bit B3 decimal value: 8
B4
status.operation.instrument.lan.trigger_overrun.LAN4
Bit B4 decimal value: 16
B5
status.operation.instrument.lan.trigger_overrun.LAN5
Bit B5 decimal value: 32
B6
status.operation.instrument.lan.trigger_overrun.LAN6
Bit B6 decimal value: 64
B7
status.operation.instrument.lan.trigger_overrun.LAN7
Bit B7 decimal value: 128
B8
status.operation.instrument.lan.trigger_overrun.LAN8
Bit B8 decimal value: 256
B9-B15 Not used Not applicable
As an example, to set bit B1 of the operation status LAN trigger overrun enable register, set
status.operation.instrument.lan.trigger_overrun.enable =
status.operation.instrument.lan.trigger_overrun.LAN1.
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 B8, set operationRegister to 258 (which is the sum of 2 + 256).
