Introduction
NetLinx
®
is the second generation of the Axcess
®
programming language and is a superset of the
original Axcess language with extensions for additional data types, new event handlers, structure
support, multi-dimensional arrays, and other features. This document assumes that you are familiar with
Axcess; the focus is on the new language elements and how they extend the functionality of the existing
language.
For background information on Axcess, refer to the Axcess Programming Language instruction manual.
For a side-by-side comparison of programming in Axcess and NetLinx, refer to the NetLinx
Programming Overview section on page 3.
Conventions Used in this Document
NetLinx contains a number of keywords that define various available operations to perform in a NetLinx
command, such as the word
CALL in the statement:
CALL 'Read Data' (Buffer)
Keywords are case insensitive. For example, the PUSH command is the same as push. Keywords are
reserved, meaning that identifiers (device names, constants, or variables) must have unique names. These
keywords are listed and defined in the Reserved Identifiers section on page 99. All references to NetLinx
language keywords in this document appear in
THE FONT SHOWN HERE, in all capital letters.
Programming examples appear in the same fixed font. For example:
DEFINE_VARIABLE
CHAR MyString[32]
INTEGER StrLen
Square brackets indicate an optional element in a command. Angle brackets indicate substitution. In the
example below, the notation
<return type> indicates that a valid data type (such as CHAR, INTEGER,
or
FLOAT) must be substituted for <return type>. The square brackets surrounding it indicate that
the return type is optional.
DEFINE_FUNCTION [<return type>] <name> [(Param1, Param2, …)]
{
(* body of subroutine *)
}
