What it does

Reports global statements at the top level of a library module.

Why is this bad?

At module level every name is already global; the statement does nothing. It often signals a misunderstanding: Ignition library modules are loaded once per project and their module-level variables are shared by every caller, which global does not change.

Inside Perspective and event scripts global is not at module level (the script is a function body) and is not reported.

Example

global cache
cache = {}

Use instead:

cache = {}
