I have an application that needs 20 inputs and 20 outputs with only 10 XNOR and 10 NAND blocks. I could do it with relays, but this could end up costing more than some PLC options. On the other hand, a PLC might be kind of overkill. What is the absolute cheapest way to do this, do you think? Keeping in mind that it requires standard industrial 24v I/O.
I whipped up the logic in some software that I already had and have attached it to this post, but that won't be the hardware I use because it is wildly expensive.
