ControLogix Structured text editor

Can anyone explain how to install the structured text editor for ControLogix?

It's probably already installed. It's use depends on the RSLogix 5000 license that you have.

If you don't have the proper licensing it will not expose it's functionality although it has been installed.

Right click on a Program folder (MainProgram is the default) and add a routine. When creating the routine there is a drop down box to specify whether you want Ladder, FBF, SFC, or STX. But again, your license will determine what choices you see here.
