Object oriented programming (OOP) is a popular programming paradigm that is widely used in software development. But did you know that OOP is also becoming increasingly important in the field of industrial automation? In this post, we'll explore why object oriented PLC programming is essential for modern industrial automation systems.

Increased Flexibility: OOP allows for the creation of reusable code, which can be easily adapted to changing requirements. This makes it easier to update and maintain industrial automation systems, reducing downtime and increasing efficiency. 

Improved Modularity: OOP allows for the separation of code into smaller, more manageable chunks. This makes it easier to test and debug industrial automation systems, and also allows for the use of different programming languages for different parts of the system. 

Enhanced Scalability: OOP allows for the creation of large, complex systems that can be easily scaled up or down as needed. This is essential for industrial automation systems that must handle a large amount of data and perform complex tasks.

Better Collaboration: OOP allows for the creation of clear and consistent code, which makes it easier for multiple programmers to work on the same industrial automation system. This improves collaboration and speeds up development. 

Object oriented PLC programming is essential for modern industrial automation systems. It offers increased flexibility, improved modularity, enhanced scalability, and better collaboration. According to various studies and surveys, companies that use OOP in their industrial automation systems experience significant benefits such as reduction in downtime, improved scalability, better collaboration and improved modularity. By learning object oriented PLC programming, industrial automation professionals can stay ahead of the curve and create more efficient systems.

I think Peter Kurhajec hit the nail on the head when he said stated in the video he did with Jakob "4 things we want in TwinCAT 4" ( https://youtu.be/dgEsib42WaA?t=813 ) that there needs to be an actual standard outside of IEC-61131-3.

Everything that is OOP is just an extension built onto the IEC-61131-3 standard. Codesys and TwinCAT 3 are much better at OOP things than Siemens TIAportal and (especially) Logix Studio 5000, but it really feels like we don't have "IT" yet. I think Siemens is coming out with Simatic AX which looks very promising.
