: Most tutorials highlight the 1789-SIM module , which allows you to manually toggle digital and analog inputs to see how your logic reacts in real-time.

In the world of industrial automation, the ability to test code without risking expensive hardware—or safety—is a superpower. For ControlLogix and CompactLogix programmers, that superpower comes in the form of .

Note: Versions 28 and earlier used a separate installer called "RSLogix Emulate 5000." Versions 30+ integrated it into the "Studio 5000 Logix Emulate" installer.

You can also add or use Aliasing to simulate physical inputs.

Emulate does not emulate physical I/O cards (like a 1756-IB16 digital input card). It only emulates the controller (CPU). To simulate inputs and outputs, you must map them to controller-scoped tags or use a separate tool (like FactoryTalk View ME Emulation or the "Simulate" module inside Emulate).
