I may be a new forum member here, but I am in no way unfamiliar with forum etiqutte.
My field is PLC Programming, and was once a technical trainer for Rockwell Automation (you may have heard of them).
I am also a regular contributor to, and moderator for, the PLCs.net community, with over 4,000 posts to date. My user-name there is the same as here.
There is absolutely no way I would have posted replies like some of the earlier ones, being as much use as chocolate teapots. Terse, unhelpful, and slightly condescending. Everyone needs some help, at all levels.
There, I've had my say, and if this post gets me barred from this forum, then so be it.
