TwinCATConveyorProblem

This was a 2-day project in which I learned Beckhoff’s TwinCAT 3 XAE and created a hypothetical solution to a problem for a job interview. I had no prior experience with Structured Text or Pascal prior to this!

Objectives

• We have an conveyor with 4 buttons Start Stop AND E-Stop AND Reset.
• When system starts it shouldnt do anything until reset.
• Starting it should speed up to a RUN_SPEED, over ACCEL_TIME and maintain.
• If stop is Pressed speed should decrease to 0 over DECCEL_TIME.
• If E_Stop is Pressed speed should go immediately to 0.
• Before resuming operation after E-Stop, the system should require a reset.
