IO672 - RT Send
IO672 - RT Send — Send message from MIL-1553 remote
terminal
Library
Simulink Real-Time - Speedgoat
Description
A Remote Terminal sends data only if it receives a transmit command from the Bus
Controller. This block prepares the board for the next transmit command on this
channel, Remote Terminal number, and sub address as specified by the Initialize and
RT Initialize blocks.
The data vector signal input to this block is copied to the board message buffer
that corresponds to the specified address. The input data vector must have the same
length as specified in the Number of words to send parameter. The input vector can
be either 16- or 32-bit signed or unsigned data. The block sends only the bottom 16
bits of each element.
Your model might have multiple Remote Terminal Send blocks. To help you locate a
particular block, the Remote Terminal Send block displays the channel number and
address parameters. The address display has the format:
remote terminal-T-sub address-number of words
Remote terminal — Derives from the Remote Terminal parameter
T — Indicates transmit (or send) command
Subaddress — Derives from the Sub address parameter
Number of words — Derives from the Number of words to receive parameter
A transmit command for RT 1, sub address 3 to send 2 words has the layout 1-T-3-2.
Ports
Inputs
- Data
Vector of data to be send.
Parameters
-
Channel
From the list of available channels on the board, choose channel 1, 2,
3 or 4. This channel is initialized for this command stream.
-
Remote terminal
A Remote Terminal from 0 to 31. The remote terminal number configured
in RT Send and RT Receive must match that specified by the corresponding
RT Initialize block.
-
Sub address
The sub address for this message.
-
Number of words to send
The number of 16-bit integers to send as the data part of this
message. This number must be between 1 and 32. The input data vector
must have the same vector width.
-
Sample Time
Defines the base sample time at which this driver block gets its sample hit. This
parameter can also be set to -1 for inherited
sample time. The units are in seconds.
