confuse`d`

its been a while since the first time i got confused of “giving instruction to PLC from PC”… at least i got 2 reliable ways answering this question… first is directly by software, which doesn’t  need any hardware addition. the second is using demux circuit.

wat keeps me confused is that both ways aren’t easy enough for a newbie like me… sHILHOTE….. oh my… i saw miss deadline keeps smiling at me, as if she was calling “come on, the train is about to go, do you want to graduate this semester?”…. ahahahaha as i said above SHILHOTE
