And Key Number — Logixpro 500 Key Name

When a lab exercise says “set Key Name to REM” or “Key Number = 2”:

A Key Number (also called a scan code or key code) is the numeric identifier assigned to each physical key on a keyboard. When you press a key, the operating system sends a unique number to the software. LogixPro translates that number into a specific input address.

Example:
Pressing the A key on your keyboard sends key number 30. LogixPro can be configured to map key number 30 to input I:1/0. In this case:

Understanding the difference allows you to: logixpro 500 key name and key number

For over two decades, the LogixPro 500 PLC simulator has been the gold standard for learning Allen‑Bradley RSLogix 500 programming. Developed by The Learning Pit, this software allows students to simulate a SLC‑500 system without expensive hardware.

However, every new user eventually hits the same wall: The License Key Screen.

Unlike modern subscription software, LogixPro 500 uses a classic “Key Name” and “Key Number” system. If you have searched for “logixpro 500 key name and key number”, you are likely staring at a dialog box asking for credentials you do not yet possess. When a lab exercise says “set Key Name

This article will explain exactly what these fields mean, how to obtain legitimate credentials, and how to avoid common pitfalls.

Requirement: Use I:1/0 (Enter key) as Start and I:1/1 (Spacebar) as Stop.
Key numbers involved: 28 and 57

Ladder:

      I:1/0          I:1/1          O:2/0
|-------| |------------|/|-----------( )---|
|       |                            |
|   O:2/0|                            |
|-------| |----------------------------|

Learning outcome: Understanding momentary vs. maintained contacts via keyboard simulation.

LogixPro does not natively allow you to change the key number assigned to I:1/0. However, you can simulate remapping by using the keyboard interrupt method:

Example: You want the G key (34) to act as I:1/0. Example: Pressing the A key on your keyboard
