Hey all, hope im posting in the right place, anyways im a studen i have posted before, i am currently working on an assignment and no i dont want the answers put to learn about it myself so i can figure them out myself, i think if someone else does the word it will show your your work, so i prefer to be taught 
, anyways my asisgnment is on selecting a plc plus writing about the different type of plc's the inputs outputs, describing what normally open /closed etc but i have to do it in 150-300 words, all the binary and decimal i have done , i have looked through this forum and have managed to get some decend pdf's and a few books, and i do have a plc program and simulator so i can test bits out, the problem i am having is although im finding bits on the different types, unitary,modular and rack, which ones are upgradeable and what they do im struggling to make it upto 300 words, also one of my questions ask me when explaining all 3 types to include scanning time versatility cost and input output specifications, most of that im actually ok with , but from what i have read there no real way ( unless you actually have one) that you can determine that due to different models have different processors and some with multiple processors, some older than others, plus also depends on the size of the program rungs, and the actual plc type itself, and the flag i understand correctly are, like statuses of whatever an output or something like that, like i say im not after someone telling me have to do my assignments i like to learn it myself, just looking for as much info as possible onto the different types, extras for them upgrades, expansions inputs outputs etc etc thank you
