Remote Terminal Attributes

RT Response Time

The KMXF_MIL1553_RT_RESPONSE_TIME attribute holds the actual remote terminal response time. 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 0
Maximum 2047

Default value: 48

RT Response Timeout

The KMXF_MIL1553_RT_RESPONSE_TIMEOUT attribute holds the actual remote terminal response timeout. Useful for RT-RT command. The response timeout indicates the maximum acceptable delay before receiving a response from another 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 0
Maximum 2047

Default value: 112

RT Default Status

The KMXF_MIL1553_RT_DEFAULT_STATUS attribute holds the remote terminal status word. This status may be “ORRED” with other bits generated by the RT itself before responding to the BC command. Any 16 bit values are supported.

The default status word includes the RT address (bit 15..11).

RT Subsystem Flag option

The KMXF_MIL1553_RT_SSF_OPT attribute holds the actual RT Sub System Flag option. This status flag may be set by the associated discrete input line or by software. RTs from channel #0 use discrete input pin #0, RTs from channel #1 use discrete input pin #1 and so on.

Constant Value
VMXF_MIL1553_RT_SSF_OPT_SOFT RT Sub System Flag set by software (default)
VMXF_MIL1553_RT_SSF_OPT_DISCRETE RT Sub System Flag set by discrete input


RT Terminal Flag option

The KMXF_MIL1553_RT_TF_OPT attribute holds the actual RT Terminal Flag option. This status flag may be set by the associated discrete input line or by software. RTs from channel #0 use discrete input pin #0, RTs from channel #1 use discrete input pin #1 and so on.

Constant Value
VMXF_MIL1553_RT_TF_OPT_SOFT RT Terminal Flag set by software (default)
VMXF_MIL1553_RT_TF_OPT_DISCRETE RT Terminal Flag set by discrete input


RT Address

The KMXF_MIL1553_RT_ADDRESS attribute holds the remote terminal address (read-only).

RT Start Time

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

Default value: 0
