XOR with four Inputs with OR-, NON- and AND-Operators

2024-11-05T17:54:27.578000Z

My topic is more of academic nature, I would like to implement an XOR-operation with four inputs on my own (without the predefined XOR-operator) in a function block diagram (FBD).
I have two proposals. One works fine and the other one is just an idea, but I do not know, if it is possible to code it in CODESYS V3.5 SP18 in form of a FBD.
Here the one that works:

And here an idea, which I have not managed to code it as an FBD:

Any ideas? Is the 2nd diagram a correct interpretation of the coding task? And is there a way to implement it in form of an FBD in CODESYS V3.5 SP18?
