I use VMWare and find it rock solid. Running on an OSX host so I can't store my licenses on the host - I have a "main" Rockwell VM (Windows 7 64 bit) which has my activations, and if I need to use...

This is not correct - it's just that (as Rob says) you have to delete the safety signature first. After that, you can do online edits.

Of course, one would never, ever do this on a system in...

I had a look at the Sepasoft module. Looks really good, but $20k? Ouch!

I can see that at the right scale it would be massively worthwhile, but for a one-machine proof-of-concept starting point,...

I had it happen on a 1756-L71 running firmware v23.

I haven't exhaustively tested it across a lot of platforms, but something like that only ever bites me once :)

A quick warning on this.

Take the example of an array of DINT's, with 10 elements. Call it DINT_Array[0] through DINT_Array[9]. Let's say you call DINT_Array[Pointer].

If Pointer has a value of...

I don't want the pressure to build up to cut-out pressure, that's the point. I want it to build up to around 150kPa and then stay there for as long as I have it set to water the plants. If I have two...

At the moment, it's all Siemens,...
