Issue

After compiling the project, I have a compilation error W1048 - Reserved Words.

Product Line

Power Scada Operation 2020

Power Scada Operation 2020 R2

Power Scada Operation 2021

Ecostruxure Power Operation 2022

Environment

Power Operation Studio Compiler

Cause

There are certain words that are restricted for use. You can find these words in the AVEVA Plant Scada manual. Reserved Words may be different version to version. Some reserved words like "Array" or "While" may result in a compiler warning. Other reserved word errors may end up causing functions to fail.

Using reserved words should be avoided as much as possible.

Resolution

Changing the name of tags, variables or equipment in the database may result in unattended consequences and errors that are difficult to trace. Please do not attempt if you are not comfortable with Power Operation/Power SCADA or Plant SCADA. If you are using TGML graphics please call into Technical Support to consult before making attempting the changes below.
