Logixpro 500 Key Name And Key Number May 2026

However, a frequent point of confusion for beginners—and a necessary concept for advanced simulation—is the distinction between 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.

I:1/0 I:1/1 O:2/0 |-------| |------------|/|-----------( )---| | | | | O:2/0| | |-------| |----------------------------| Learning outcome: Understanding momentary vs. maintained contacts via keyboard simulation. 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. Exercise 3 – Numeric Keypad Entry Use keys 0‑9 (key numbers 11,2,3,4,5,6,7,8,9,10) to enter a 4‑digit passcode into an integer register (e.g., N7:10 ). Compare the result to a preset value (e.g., 1234) to unlock a door. logixpro 500 key name and key number

| +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. Below is an expanded reference table of key numbers that work reliably in LogixPro 500 (US keyboard layout). Use these to design custom keyboard interfaces. However, a frequent point of confusion for beginners—and

Introduction 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. maintained contacts via keyboard simulation
