  1. Why does Q = output?

    After doing some more research I discovered that as well. I'm still very curious as to the explanation behind Q being used to symbolize Output. As I stated above, an I looks like a 1 so why do they still use I for input?
  2. Why does Q = output?

    Well an I looks like a 1. That does not sound like a reasonable explanation.
  3. Why does Q = output?

    Hello, Some co-workers and I have recently started learning Siemens after spending our professional lives in Allen-Bradly world. One thing we cannot wrap our heads around is that in Siemens, the short hand for output is Q. In AB world your inputs and outputs are labeled I and O respectively, but in Siemens world inputs and outputs are I and Q. We asked several more knowledgeable co-workers about this and they had no clue (I guess it never occurred to them). In what language does Output begin with a Q? Was it just a random decision when Siemens was first in development? Thanks.
