Engineers! Have you ever inherited an extremely large GX Works3 project which uses tons of Global Labels?

Wondering which Global Labels are used or unused?

This guide will show you how to Identify which Global Labels are used or unused so that you can carry on and change/modify your PLC project without clashing your devices!

Duplicating or overriding Global Labels can lead to compilation and programming errors.  So it is a good idea to know what Global labels are available and unavailable.

As GX Works3 has a large range of settings throughout, this one setting can be quite difficult to find.  We have created this guide to locate and show you exactly where this useful setting is.
