Logixpro 500 Key | Name And Key Number

Here's a closer look at the two components of your LogixPro 500 registration key:

Key Name is I (Input), Key Number/Slot is 1 , Terminal Bit is 0 . This typically represents the first switch on the simulator board. logixpro 500 key name and key number

Instead of wiring real hardware, you use the to interact with your logic. Each virtual device has a Name (for identification) and a Number (for addressing). Here's a closer look at the two components

You cannot simply copy a Key Number from an old computer to a new one. The new computer will have a different Key Name, requiring a new matching Key Number. Each virtual device has a Name (for identification)

| Symptom | Likely Cause | Solution | |-----------------------------------------|-----------------------------------------------|--------------------------------------------------------------------------| | Pressing a key does nothing in LogixPro | Keyboard interrupt not enabled | Go to Simulation → Keyboard Interrupt and enable it. | | Random keys trigger inputs | Another application has focus | Click inside the LogixPro window to give it focus. | | Key number always shows 0 | No interrupt or wrong register address | Ensure N7:x address matches the one in your EQU instruction. | | Arrow keys move cursor instead | LogixPro’s “Use arrows for navigation” active | Disable navigation mode: Simulation → Keyboard Options → Uncheck. | | Enter key resets simulation | Conflict with default menu shortcut | Remap I:1/0 to a different key (e.g., the F12 key, number 88). |
