Programming example for real PLCs.

Includes problem statement and solutions for three automation systems:

-EasyPLC (Nirtec)

-TIA PORTAL v.15 (Siemens)

-RSLogix 5000 (Rockwell)

The objective is to classify the three part types using only one capacitive sensor.

Operating instructions for the proposed system:

Three types of pieces will circulate through the conveyor, each one of a specific material and height, a capacitive sensor will be used to detect the height of each piece, which must be activated when the piece is detected by the SW1 photocell.

The pieces will circulate through the conveyor and will be classified upon reaching the classification area with the three ejection systems.

The capacitive values for each piece are:

Cardboard Part -> value: 0.474 

Wood Part -> value: 0.374 

Metal Part -> value: 0.624

The part classification must be as follows:

– The wood parts must be ejected by Ejector 1

– The cardboard parts must be ejected by Ejector 2

– The metal parts must be ejected by Ejector 3

Use a queue data structure to manage the part data in order when the parts arrive to the classification positions, the queue will be read to classify the part.
