ISA announced a couple of days ago that a whole group of Honeywell and Yokogawa instruments and devices had completed WCI-compliance testing and were now certified ISA100.11a devices. That's cool.
Or is it?
Which ISA100.11a were these devices certified against?
ISA100.11a-2009, which was withdrawn from the ANSI approval process?
ISA100.11a-2010, which is being re-written with some significant changes from the 2009 model year and hasn't been approved yet?
