I too thought that ladder logic is horrible (and for certain tasks, it is).

Ladder logic predates PLCS though- essentially the same notation was used when relays were used to implement it, and EEs were fine with that.

Yeah, this strikes me as being at the logic gate level, not the functions and expressions level.

That said, a complicating element is that PLCs can extend the basic diagram with custom blocks...
