PML Customisation User Guide

Introduction

The PML Customisation Guide describes how to use PML, the AVEVA Programmable Macro Language and should be used together with Summary of Objects, Members and Methods.

You do not have to be a professional programmer to start to learn PML, although you may find this manual difficult to follow unless you have some understanding of programming concepts such as if statements and do loops. If you have no programming experience, you should consider attending a PML Training Course.

The current version of PML, sometimes referred to as PML2, may simply be seen as an extension to the original PML1 facilities. However, the more powerful techniques that are available mean that many programming tasks are carried out in different ways.

There are some tasks which are carried out more efficiently using PML 1 facilities. These are described in this manual where necessary, you should also refer to Expressions.
