CHAPTER 2 CREATING PROJECTS
2.3. Working with Tags
A tag represents a single input or output variable monitored or controlled by the system. By changing tags, you can use
any PLC or controller without re-developing the application. This chapter explains how you can define and manage tags by
tags editor.
After the tag is created in tags editor, you can use it in your application by Select Tag Dialog Box. Please see
Section
4.4.3.3 Selecting Tags for details. Or you can specify the tag by yourself. The format of a tag is Link Number\Tag Group
Name\Tag Name.
For example:
Tags Description
1\MONITOR\CORE DISPLAY Indicates a local tag named CORE DISPLAY in MONITOR tag group of link 1
0\BOT\DECLARE Indicates a local tag named DECLARE in BOT tag group of internal memory
0\_ALARM SHOW Indicates a global tag named _ALARM SHOW of internal memory
Note that the maximum text amount of the tag/tag group name is 48 characters. You are allowed to define not only tags for
the link but also the tags for a tag group of the link.
2.3.1. Types of Tags
In PM designer, there are two types of tags: global tags and local tags.
■ Global Tag
A global tag is a tag that can be used by all panel applications in the same project. With global tags, the panel applications
in the same projects can share the common address declaration without having to keep and maintain the same set of tags
locally.
Note that a global tag can be only associated with internal variables.
■ Local Tag
A local tag is a tag that can be only used by the panel application which the tag is located in.
