 Procedure
This procedure explains the process for programming the application examples.
1) Set characters (terminating characters) "LF" to indicate the ending of the character string.
2) Open channel 1to use channel 1 in the RS232C unit.
3) If channel 1 receives a signal, the first column of the local string takes the signal in.
4) When the received data is "HOME", Axis-2 performs homing. After homing is completed, an "OK" signal will
be sent back.
5) When the received data is "MOVE", the velocity data is converted into binary notation and set in variable 10. The
position data is also converted into binary notation and set in position no.1. When the motion is completed, an
"OK" signal will be sent back.
