Set up
You need the SETCOM command to set up the serial port of the TJ2-MC64
for the Host Link Slave protocol. Set the command as follows:
SETCOM(baudrate, data_bits, stop_bits, parity, port, 5)
After you have set this command, the TJ2-MC64 responds to Host Link
commands from the master with the specified node number. You can set this
node number with the HLS_NODE parameter.
Example
In this example we assume this set-up:
• A Trajexia system with a TJ2-MC64.
• An NS8 programmable terminal.
• A connection from the serial port of the TJ2-MC64 to the programmable
terminal. The serial port uses RS232C communication.
/i
Example Configuration of the Host Link slave.
BASIC code ' Define Host Link slave node
HLS_NODE = 15
' Define Host Link slave model code
HLS_MODEL = $FA
' Set up Host Link slave for port 1
SETCOM(9600,7,2,2,1,5)
Result The TJ2-MC64 can communicate with the programmable terminal.
Solution
Correct the command
data and transfer the
command again.
