Chapter 7 Application
Programming

Overview

The DMC-1600 provides a powerful programming language that allows users to customize the
controller for their particular application. Programs can be downloaded into the DMC-1600
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. Only ASCII
commands can be used for application programming.
In addition to standard motion commands, the DMC-1600 provides commands that allow the
DMC-1600 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-1600 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. The
program memory size is 80 characters x 1000 lines.

Using the DMC-1600 Editor to Enter Programs

Application programs for the DMC-1600 may be created and edited either locally using the DMC-
1600 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-1600 provides a line Editor for entering and modifying programs. The Edit mode is
entered with the ED instruction. (Note: The ED command can only be given when the controller
is in the non-edit mode, which is signified by a colon prompt).
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 last
program in memory. If desired, the user can edit a specific line number or label by specifying a
line number or label following ED.
