To build a functional CODESYS elevator project, you must first define your physical inputs and outputs (I/O):

Use an integer variable to track the "Current Floor" updated by physical or virtual limit switches. codesys elevator project

The "Elevator Algorithm" usually prioritizes calls in the current direction of travel before reversing.

Device (PLC – e.g., Raspberry Pi, BeagleBone, or SoftPLC) ├─ PLC Logic (Application) ├─ Global Variables (GVL) ├─ Visualization Manager ├─ Trace (for debugging motion) └─ Task Configuration ├─ MainTask (cyclic, e.g., 20ms) └─ SlowTask (door timers, 100ms) IF NOT movingUp AND NOT movingDown AND NOT

A standard CODESYS elevator project controls:

END_CASE

Better projects even include a of the car moving up/down.

The "brain" of your elevator typically follows a architecture to handle different operational modes (e.g., Idle, Moving Up, Moving Down, Door Opening). Determining Direction The "brain" of your elevator typically follows a
