IBM 610 workstation computer 3377

Hey, I had one of those :) The remote system (SCADA - PLC communicating via a spread spectrum radio) was down most of the last year or so. Now it's a desperately needed box...

hehehe.

They also can't understand why we (or they) can't get modules anymore. I think someone realized that a changeout (mbuttive now) will be needed, but they think they've got an 'upgrade path' to a 'newer' version of the same vendor's crap. AFAIK, none exists. We've been pushing GE Versamax and 90-30, but a few there don't want it even though they have a few of 'em already and they work. As one cow-orker puts it, Modicon PLCs are the only ones you ever get random failures on. They litterally up and die for no reason, and quite often. I call 'em Modicrap even right to the distributor rep's face...

I deal with decimals on PLCs (which generally make floating point calcs as awkward as possible) by just shifting the decimal over and ignoring it. Thus, a 1.35 foot level becomes 135. Scale the input as needed, ignore the decimal, and do whatever little adjustments we need due to multiplication or division, though we avoid that as much as possible too..
