I just noticed your introduction of the CLICK PLC family. I went to the manuals looking for the instruction set (real and trig) and didn't find any. But I did find a link to the NEW programming software. It looks like a very nice evolution of DirectSOFT with a better integration to a Graphical User Interface (GUI). It includes more information about the elements involved including whether the variable is retained or not. It also suggests that with all-status-on you'd be able to see the values right in the representation of the element. This is very good.
Is this new GUI going to be available in DS? Would it be DS6?. DS7?. Never? If you're still collecting votes, I'd cast mine for this interface for ladder logic.
