Logixpro 500 Key Name And Key Number 〈100% PREMIUM〉

You can create a simple keypad emulator:

|   +EQU+             +OTE+
|--|N7:0| 2           | B3/1 |  (Key '1')
|
|   +EQU+             +OTE+
|--|N7:0| 3           | B3/2 |  (Key '2')
|
|   +EQU+             +OTE+
|--|N7:0| 4           | B3/3 |  (Key '3')

This approach is more memory‑efficient than using 16 separate input bits for 16 keys.

When you install LogixPro 500, the first launch presents a license dialog. It contains two distinct fields: logixpro 500 key name and key number

Together, these form a paired license. The software runs a checksum: if the Name and Number do not match the proprietary algorithm, the simulator locks itself into “Demo Mode.”

LogixPro does not require you to manually “map” the key number to a name; the name “M key” is simply your documentation. In your rung comment, write:
"M key (key number 50) controls output O:2/0" You can create a simple keypad emulator: |

Once you have legitimate credentials, follow this precise process:

For students, technicians, and automation engineers learning Programmable Logic Controllers (PLCs), LogixPro 500 is a cornerstone simulation software. Developed by The Learning Pit, this powerful tool mimics the Allen‑Bradley RSLogix 500 environment, allowing users to practice ladder logic programming without physical hardware. This approach is more memory‑efficient than using 16

However, a frequent point of confusion for beginners—and a necessary concept for advanced simulation—is the distinction between Key Names and Key Numbers. Understanding how LogixPro 500 interprets keyboard inputs (key names) and their corresponding internal numeric codes (key numbers) is essential for designing Human‑Machine Interface (HMI) simulations and troubleshooting event‑driven logic.

This article provides a comprehensive breakdown of LogixPro 500 key names, their associated key numbers, how to use them in ladder logic, common exercises, and troubleshooting tips.

Use arrow keys (Up=72, Down=80, Left=75, Right=77) to control a simulated conveyor direction.
Store key number in N7:0 and use four separate EQU instructions to drive four different outputs.
