BC Response Timeout

The KMXF_MIL1553_BC_RESPONSE_TIMEOUT attribute holds the actual bus controller response timeout. The response timeout indicates the maximum acceptable delay before receiving a response from an RT. On IPM-1553-MRT the effective resolution is 1 bit, the value will be rounded down to the nearest bit (i.e. 33 ⅛ bit will be set to 32 ⅛ bit).

Range	Value (⅛ bit)
Minimum	8
Maximum	2047

Default value: 112

BC Global Bus Selection

The KMXF_MIL1553_BC_GLOBAL_BUS_SELECTION attribute holds the bus controller global bus selection. This attribute can override the bus selection made when configuring the command to be transmitted.

Constant	Description
VMXF_MIL1553_BUSSELECTION_A	Command will be transmitted on bus A.
VMXF_MIL1553_BUSSELECTION_B	Command will be transmitted on bus B.
VMXF_MIL1553_BUSSELECTION_BCMSG	Command will be transmitted on bus configured by the command. (default)
VMXF_MIL1553_BUSSELECTION_BCMSG_ALT	Command will be transmitted on opposite bus configured by the command.

BC Start Time

The KMXF_MIL1553_START_TIME attribute holds the time at which the bus controller has been enabled. Supported on Enhanced module only.

Default value: 0

BC Aperiodic FIFO Almost Full Threshold

The KMXF_MIL1553_BC_APER_FIFO_AF attribute holds the almost full (AF) value for the bus controller aperiodic FIFO, in number of words.

Range	Value (word)
Minimum	2
Maximum	255

Default value: 32

BC Aperiodic FIFO Almost Empty Threshold

The KMXF_MIL1553_BC_APER_FIFO_AE attribute holds the almost empty (AE) value for the bus controller aperiodic FIFO, in number of words.

Range	Value (word)
Minimum	1
Maximum	254

Default value: 16

BC No Response Detection

The KMXF_MIL1553_BC_NORESP_DETECTION_ENABLE attribute holds the BC No Response Detection State. See BC Acquisition Service chapter for more information. Supported on Enhanced module only.
