I have been working with PLC programming and debugging for the past 3 years. I have experience in programming and debugging PLCs from various brands such as Siemens, Allen-Bradley, Omron, etc.
For example, I have programmed a Siemens S7-1200 PLC to control a conveyor belt. I wrote the ladder logic code to move the conveyor belt forward and backward, and also wrote a routine to detect when an object is present on the conveyor belt. I then debugged the code to ensure that the conveyor belt was operating correctly.
