here is the correction that you asked for ...
OK ... now we're getting somewhere ...
the MISTAKE that you're making now is in considering that:
1 equals TRUE ... and that
0 equals FALSE ...
that is a VERY popular misconception – and it will cause you much confusion if you continue to look at it that way ...
the following is covered in the videos – watch for it and learn ... but here is a preview ...
a BIT is a BOX ... the bit/box can hold either a ONE or a ZERO ...
do NOT (I repeat, do NOT) make things difficult by saying that the bit/box is either TRUE or FALSE ... specifically, bits/boxes are NEVER either TRUE or FALSE ... they just hold either a ONE or a ZERO ...
quick question: have you ever looked at a PLC data table (the bits/boxes) and seen either a "T" for true – or an "F" for false stored there? ...
answer: no, the only thing that you can ever possibly see in a bit/box is either a ONE or a ZERO ... but many people insist on confusing things by describing the bit/box status using the terminology "true" and "false" - instead of ONE and ZERO ...
going further:
again - the following is covered in the videos – watch for it and learn ... but here is a preview ...
XICs and XIOs are INSTRUCTIONS ... regardless of what the official books say, these instructions do NOT "function as an input or storage bit" ... specifically, these are NOT "bits/boxes" ...
now then ... an XIC instruction can be either TRUE – or it can be FALSE ... specifically, it can NOT be a ONE or a ZERO ...
again – watch the videos and you'll see those points made several times ...
summing up ...
(1) in the bit/boxes you have ONEs and ZEROs ... you do NOT have TRUE or FALSE in a bit/box ...
but on the other hand ...
(2) an XIC or XIO instruction can be either TRUE or FALSE ... you do NOT have ONE or ZERO as the result of an instruction ...
I say again:
you need to watch those videos ...
all eleven of them ...
IN NUMBER ORDER ...
but at least now you're FINALLY starting to make real progress ...
party on ...
