Sorry I'am late on this. Have been away from the forum with my head in panels =) I think there is certainly an expectation in the industrial automation world for sync. I learned programming in C++ and Java and I was confused at first about how ladder scans from the top down and how conditions can screw your program up (ie latching and one shots). It would be nice if you could force NR do one or the other depending on the application. I do heat process which is SLOW, for what I deal with I think I could do control w/o a PLC entirely and synchronous execution doesn't matter that much - just needs to be in the ballpark-. My buddy who does packaging on assembly lines does crazy shit where the conveyors are moving insanely fast with photo eyes and one little mistake the whole line clogs up and crap flies everywhere. I don't think he could use NR for really anything except maybe logging. So yea the expectation of synchronous execution could get you into trouble. I guess for now test the hell out of it, depends on tolerance of your application.
