drbitboy, you read correctly that the word "good" was significantly modifying the phrase "no workarounds". ...
Yah, if I had this handed to me, with a small capital budget, and where my time was properly valued, I might consider tossing the -232ASC and implementing the RS-232 interface and data parsing in a RaspberryPI for all of maybe $50-100 in parts, which would be all but trivial in this case, and then have that communicate with the PLC over ethernet, plopping the data into some tags that the PLC could check every scan, no PLC TONs and the rest of the schlock required. To be sure that's a rube goldberg/heath robinson approach, but I suspect coding anything like this properly in a PLC is painful, even if with the right interface card.
Maybe the HMS AB7072 you suggest does summat similar?
