[Path]<PathName>

Defines a substitution data path in the project's system parameters. You can specify logical data paths (for data storage and retrieval) on your system. You can then use a data path shortcut instead of entering the full path to the data.

For example:

[path]trenddata=c:\data\mytrends

In this case, trenddata is defined as the shortcut to the c:\data\mytrends path. This shortcut can be used in Plant SCADA forms. For example, a trend tag's "File Name" field may contain the string:

"[TRENDDATA]:\trend_fast_00001".

Plant SCADA then expects the trenddata path to be defined in the system parameters or in the INI file. The reserved shortcut names which the system uses can be found in topic Using Path Substitutions.

If one of these reserved path names are used, a "Path not suitable" error is raised on system startup.

Note: You will need to manually configure the access control list for a folder specified in a path substitution so that it matches the permissions that were applied to the default location during installation. See Configure Directory Security for Modified Folder Locations.

To define (or change a path substitution):

1. Choose System | Parameters.

2. In the Section Name box, enter PATH.

3. In the Name property, enter the path substitution string.

4. In the Value property, enter the full data path.
