Chapter 5 Command Basics

Introduction

The CDS-3310 provides over 100 commands for specifying motion and machine parameters.
Commands are included to initiate action, interrogate status and configure the digital filter. These
commands can be sent in ASCII or binary.
In ASCII, the CDS-3310 instruction set is BASIC-like and easy to use. Instructions consist of two
uppercase letters that correspond phonetically with the appropriate function. For example, the
instruction BG begins motion, and ST stops the motion. In binary, commands are represented by a
binary code ranging from 80 to FF.
ASCII commands can be sent "live" over the bus for immediate execution by the CDS-3310, or an
entire group of commands can be downloaded into the CDS-3310 memory for execution at a later
time. Combining commands into groups for later execution is referred to as Applications
Programming and is discussed in the following chapter. Binary commands cannot be used in
Applications programming.
This section describes the CDS-3310 instruction set and syntax. A summary of commands as well as a
complete listing of all CDS-3310 instructions is included in the Command Reference Manual.

Command Syntax - ASCII

CDS-3310 instructions are represented by two ASCII upper case characters followed by applicable
arguments. A space may be inserted between the instruction and arguments. A semicolon or <return>
is used to terminate the instruction for processing by the CDS-3310 command interpreter.
NOTE: If you are using a Galil terminal program, commands will not be processed until an <return>
command is given. This allows the user to separate many commands on a single line and not begin
execution until the user gives the <return> command.
IMPORTANT: All CDS-3310 commands are sent in upper case.
For example, the command
PR is the two character instruction for position relative. 4000 is the argument which represents the
required position value in counts. The <return> terminates the instruction. The space between PR and
4000 is optional.
