Condor QPCI-1553 Remote Terminal Send (RT) block
xPC Target Library for MIL-STD-1553
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 subaddress.
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 only sends 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 number and address parameters.
The block display has the format
remote terminal-T-subaddress-number of words
Remote terminal — Is the Remote Terminal parameter
T — Indicates transmit (or send) command
Subaddress — Is the Sub address parameter
Number of words — Is 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.
From the list, select from 1 to 4. Ensure that you have initialized this channel with the PCI-1553 Initialize and RT Initialize blocks.
From the list, choose a Remote Terminal from 1 to 31. Select the Remote Terminal number for this message.
From the list, choose a subaddress from 1 to 31. Select the sub address for this message.
Enter 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.
Enter the base sample time or a multiple of the base sample time.
If only one board of this type is in the target PC, enter
-1
to automatically locate the board.
If two or more boards of this type are in the target PC, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber, SlotNumber]. To determine the bus number and the PCI slot number, type
getxpcpci
