Chapter 7 Application
Programming
Overview
The DMC-1000 provides a powerful programming language that allows users to customize the
controller for their particular application. Programs can be downloaded into the DMC-1000 memory
freeing the host computer for other tasks. However, the host computer can send commands to the
controller at any time, even while a program is being executed.
In addition to standard motion commands, the DMC-1000 provides commands that allow the DMC-
1000 to make its own decisions. These commands include conditional jumps, event triggers and
subroutines. For example, the command JP#LOOP, n<10 causes a jump to the label #LOOP if the
variable n is less than 10.
For greater programming flexibility, the DMC-1000 provides user-defined variables, arrays and
arithmetic functions. For example, with a cut-to-length operation, the length can be specified as a
variable in a program which the operator can change as necessary.
The following sections in this chapter discuss all aspects of creating applications programs.
Using the DMC-1000 Editor to Enter Programs
Application programs for the DMC-1000 may be created and edited either locally using the DMC-
1000 editor or remotely using another editor and then downloading the program into the controller.
(Galil's Terminal and SDK-software software provide an editor and UPLOAD and DOWNLOAD
utilities).
The DMC-1000 provides a line Editor for entering and modifying programs. The Edit mode is entered
with the ED instruction. The ED command can only be given when the controller is not running a
program.
In the Edit Mode, each program line is automatically numbered sequentially starting with 000. If no
parameter follows the ED command, the editor prompter will default to the last line of the program in
memory. If desired, the user can edit a specific line number or label by specifying a line number or
label following ED.
