There are certainly some Do-more-isms that can be retro-fit into DirectSoft, and we'll make note of all requests...however...some of what we are able to do in Do-more is a function of a *big* redesign of internals and a completely new control engine. A frustrated user over on ADC's forum made the comment that DSP6 was "lipstick on a pig", and sadly there is some truth to that. The programming package is exactly that...a pretty face on the controller...but the controller is what it is and DL is substantially a 20+ year old engine. IBoxes were Host's best effort to enhance the PLC's feature set, but there is only so much that you can do.
While it would be possible to rewrite DirectSoft to 2015 standards and I'm sure we could greatly improve the programming environment itself, such an effort could never begin to return the required investment. So what we have tried to do is pick and choose some of DmD's more useful stuff and move it to DirectSoft, but obviously we can only do this where PLC and software architecture permits. Of course even DmD still contains enough DirectSoft legacy that we are still working to bring certain aspects of it up to 2015. We were just having a discussion about when we were going to break down and rewrite the ladder editor to current standards (full undo/redo, drag and drop, etc) and when we would start trying to put an SFC face on Stage. Seems likely that Rel 3 is the answer to both, but we'll see.
So...summary point...please tell us what you you'd like to see in DSP6.1 and beyond, but also understand that there are limits to what we can do within the framework we are operating in.
