Logixpro 500 Key Name And Key Number < QUICK | 2027 >

LogixPro 500 is a popular PLC simulator used by students and instructors to learn ladder logic, I/O addressing, and industrial control concepts without hardware. Below is a focused, engaging guide to understanding the key names and key numbers you’ll encounter in LogixPro 500—what they mean, how they’re used, and why they matter.

Suppose you want the M key (key number 50) to control output O:2/0 (a pilot light in the simulator).

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. logixpro 500 key name and key number

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. LogixPro 500 is a popular PLC simulator used

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.

When a lab exercise says “set Key Name to REM” or “Key Number = 2”: Use arrow keys (Up=72, Down=80, Left=75, Right=77) to

A Key Name is the descriptive label you see on the simulation panel.

Examples:

These names help you visually identify which input you are triggering. You cannot change these names; they are fixed to the simulation objects.
