No. That is old military stable, mostly industrial grade alcohol and some confiscated Cognac. Tastes like an alcohol. Not clean enough for cleaning and not tasty enough for consumption. Perfect for Finns. :lol:

We have this on the wall at work.

I've been unable to work in the workshop all yesterday due to a plague of flies - literally thousands of them, but I think I've now got them down to manageable numbers, with just the odd one or two pingng off fluorescent light tubes. I think something must have died on the roof.
So now back in and working I've been doing a bit more investigation of what I can see in the PLC via STEP5. The PLC program comprises 'blocks' of instructions, arranged as 'organisational blocks', 'program blocks', 'function blocks', 'sequence blocks', and 'data blocks'. One of the myriad of STEP5 facilities is to download these various block either by their reference numbers, or all together as one file. Trying the latter approach (as I don't yet know the reference numbers' seems to start off OK, loads of data being transferred, then everything locks up, STEP5 freezes, Program Manager shows it's using 100% of the CPU time, and the only way to stop it is to use Program Manager. When PM stops the program the entire operating system crashes - yes this is repeatable :bang:
So what blocks do I know should be there - apparently all the PLCs have OB 1, which is the interface between the operating system in the 820T controller and the user program. So I set it up to down load OP 1 - and it did it ! But I can't find how to read the file I've downloaded !
OK what else can I do - well there are various internal things in the PLC that can be brought up on the screen - not yet familliar enough to know what it all means but I suppose it's a bit more progress - have a few screen shots !

Is it downloading to a file or memory?
