All of your tasks are possible, however, it would be nice to know what kind of process or machine your task has you programming for. You could just make up some things, like scaling factors and such. Without a specific goal of operating some kind of item or process, your efforts will be much more difficult. Most often, there is a fair amount of paper work required before beginning to write programming code. This is the thought process, writing code is mostly just transcribing your thoughts into something the PLC can understand. Don't try sitting in front of the computer at the keyboard and program out of your head. This approach leads to much frustration, and is hard on the computer equipment.(Banging keyboards, and other hardware)
