Programming Basics 49
Starting, Pausing, and Halting Programs
Once downloaded to a controller, you can control programs from
the SYS prompt, as well as any PROG or PLC prompt. You must
include the program or PLC number when issuing the command—for
example RUN PROG0, or PAUSE PROG0, or HALT PROG0. The following
commands provide immediate program control from a terminal
editor:
Running a Program
While the program starts, the controller returns to the SYS, PROG, or
PLC prompt. You can then enter immediate commands as the
program runs.
To start a program, send the RUN command.
Running a Program at Power Up
You can set a specific program to automatically start after powering
up or rebooting the controller,
In the program editor, enter the PBOOT command as the first line
in a program.
Listening to a Program
While a program is running, you can “listen” to it. The listen mode
displays data from the controller’s print statements and error
messages.
To enable the listening mode on a running program, send the
LISTEN command.
To exit the listening mode, press the
ESC key (ASCII 27).
Viewing a Running Program
You can also start and listen to a program using a single command.
This is best used for development trouble shooting purposes. It is the
only time you can view program syntax errors.
To start a program with the listening mode enabled, send the
LRUN command.
To exit the listening mode, press the
ESC key (ASCII 27).
Halting a Program
You can stop motion and end program execution from the SYS,
PROG, and PLC prompts using the HALT command.
NOTE: To terminate a program in the middle of execution based
on a condition, use the END command.
To stop a program, send the HALT command.
