I don't think that any such top level tags are warranted. A short/medium length article with 23 references, written in wording that is pretty friendly to non-experts. As far as "OR" the tagger should which part they believe is O/R. <b style="color: #0000cc;">''North8000''</b> ([[User talk:North8000#top|talk]]) 19:59, 11 February 2020 (UTC)
:I added this tags mainly as a response to the lates series of edits, but even before there were problems. About half of all statements lack any reference. At first, I just wanted to tag them inline, but there's quite many of them. I don't always question their validity, but the source is still welcome. {{break}} When it comes to [[WP:OR]], section [[https://en.wikipedia.org/wiki/Programmable_logic_controller#Programmable_logic_relay_(PLR) | Programmable logic relay (PLR)]] comes to my mind as it seems to come from personal knowledge or opinion. {{break}} When it comes to being too technical – it's not bad, but it uses jargon in places that I feel it can be avoided. I also dislike this bit: ''Examples of this would be an output address could be called “O”, “Y”, or “Q”. Some models of PLC have addressing in tables to organize data (N:7, DB12.DBW0), whereas other models permit you to use free text entry in a “Tag” format (ThisTagHere). Logic and process flow would operate the same between the differing models should the correct equivalent programming is entered.'' — [[User:K4rolB|K4rolB]] ([[User talk:K4rolB|talk]]) 21:28, 11 February 2020 (UTC)
