I've seen a lot of discussion recently around UDTs, InOut interfaces, asset-oriented programming and the loss of cross referencing in TIA Portal.
In this video I share my thoughts on the topic, why the criticism exists, where I think it is justified, and why I still prefer a structured asset-oriented approach when developing PLC software.
This isn't a tutorial, it's simply a discussion based on my own experience developing automation systems and building reusable libraries.
Topics discussed (rambled about):
• UDTs (User Defined Types)
• InOut parameter passing
• Pass-by-reference vs instance data
• Cross referencing limitations
• Asset Oriented Programming
• Library management and dependency control
• Reusable PLC software design
• Siemens TIA Portal

If you have a different opinion, or a different way of approaching structured programming, I'd love to hear your thoughts in the comments.
