CNC Programs vs. PLC Programs

CNC vs PLC, What's the Difference?

CNC Programs - Software Operation:

The CNC program is a computer program, as such, the computer that controls the CNC machine, multitask. Computer-aided design (CAD) software like Mastercam software generates a 2D drawing or 3D solid model of the component to be developed, which gets imported into Computer-Aided Manufacturing (CAM) software.

CAM software generates tool paths, a series of Cartesian coordinates through which the cutting tool's tip travels and converts these into a series of basic programming language instructions. This CAM-generated set of instructions and coordinates is the CNC program that controls the CNC machine. (See left side of the picture above.)

PLC Programs - Software Operation:

The PLC acquires information from linked sensors or input devices, executes data processing, and triggers outputs as per the pre-programmed parameters. According to the inputs and outputs, PLC programs monitor and store the run-time data like machine productivity or operating temperature, automatically start and stop processes, and more.

Three fundamental steps are involved in the operation of all PLC programs, which continually execute in a repeating loop -

1. PLC Input Scan

2. PLC Program Scan

3. PLC Output Scan

(See right side of the picture above.)

TIP: The greatest opportunities (available jobs, highest pay) for machinist is in the Eastcoast States. Virginia had the most openings in 2020, Maryland had the highest average pay. The one state that is not on the east coast but made the top 10 best places to work in 2021 was Oregon.

PLC OOP Programming Language Examples

PLC OOP Programming Language Examples :

Learn By Doing IEC-61131-3 OOP Programming Examples In CODESYS

PLC OOP Programming Language

As PLC programming has been coming more focused on Structured Text and other computer-like programming languages as opposed to Ladder Logic (the simple language of electricians), those working with PLCs need to have at least a basic understanding of object-oriented programming (OOP) programming method.

About The Object-Oriented Programming Language in PLCs


OOP is a way to package computer code or PLC (Programmable Logic Controller) instructions into reusable blocks or "objects" that can be used multiple times in a program or in other programs. OOP is a way to add structure to a program and keep program sections separate from one another so that the program does not end up with "spaghetti code" where multiple instructions affecting multiple elements are all mixed up together. OOP is not a new programming language in-and-of-itself, but rather a way to package code to make programs more efficient, reusable, and modifiable. High-level computer languages like C and C++ have used OOP for years, and recently OOP has crept into the programming of PLCs and has been added to IEC-61131-3 OOP.  


OOP is not a specific programming language, it is a methodology. Another PLC Object-Oriented Programming example is the one the PLC programming software uses itself. The learner from this course will be well familiar with dragging a timer instruction onto the output of a rung of logic. That timer instruction dragged is an object class, and the resulting copy on the rung is an instance(copy) of that class. It is encapsulation in object-oriented programming.
