Does Data view only work while online? I am currently away from the processor but going through the code and HMI trying to make Heads or Tails from this. When I search for that value it comes back with "nothing found".

I agree with you about how it should work but I just can't see which one is or how the program is telling it to turn on. I feel like there should be a move command or something to put that binary value into the WORD but I'm not getting anywhere with that theory.

Thanks,

Yes, data view only works online. Sorry, I pictured you sitting there with the PLC.

I'm not sure what to tell you. If I were wanting to turn on a series of outputs with a simple word write then I would probably use the LD box to load a BCD number then write it with the OUT box.

Good Luck.

The VY6xxxx addresses are word aliases. In other words they just mimic what the actual Y bits are in a word format.

Same idea with VX6xxxx, VC6xxxx, etc. it's just another way of looking at the bits as a word.

Ok, I think I'm getting somewhere here. I have a calculation that I found while digging through the Lookout Direct Source file. See if any of you can tell whats going on, I vaguely know what the calculation is doing but not enough to explain it or to feel good about it.

(trunc(((YSW07/2`1) - trunc (YSW07/2`1))*2))

This does this for "17" more times, so I know this is doing something to see which output is on within that word but I can't figure out exactly what's happening.

Where YSW07 = V40512...which as we now know has an alias of VY240.

So in turn...this is saying YSW07 = Y240 I believe. Therefore Y240 is a word and technically has "17" outputs correct? Y240.0 - Y240.16?

I think I'm talking this out enough it's either making sense or I'm going crazy but somebody I'm sure will let me know either way .

As for that calculation...anybody understand it?
Of course chime in where ever else you feel is necessary.

Thanks again!

I don't think it is correct to say that Y240 is a word. Y240 refers to the least significant bit in word V40512. For this use a word will only have 16 bits, never 17.

With PLCs, there are lots of ways to look at the same data. If you monitor bit 0 of V40512 then you are monitoring Y240, just in a different format. If Y240 is on then I know that bit 0 in word V40512 is a 1, also if Y257 is on then I know that bit 15 in word V40512 is on.

I couldn't find a reference to YSW in the D2 manual.

Hopefully I'm helping and not confusing you more.

.
The ysw reference may be in the lookout direct manual. It's been a while since I have done anything with lookout. if I get time today I will try and refresh myself

YSW0 would be a variable.

They are bringing the bits in as a word to save on the number of connections (each connection is defined as a request from an external device for a variable) in LookoutDirect. If they brought them in as individual bits, you would have 16 connections, as a word you have 1.

LookoutDirect only allows 500 total connections.
