Why use OPC with CX-Supervisor anyway, can you not just use in-built CX-Server?

Thanks Mickey, I did a ML1100 recently, and used the SCL, not knowing that the SCP was available. It is right at the end of the instruction selection in my RS500 anyway.... I will now know for next time!!

Yep, but this instruction is not available in all Processors...

No problem, that is the purpose of these forums!!

Possibly 2x different units, from the same value? -100 to +100 & 0-100% ? That is what the values it the SCL instructions are calculating, to 1dec place of course... I have seen this done before, for different reasons...

This may help you? http://www.google.co.nz/#hl=en&source=...1260b6e98e5b160 Looking at those log messages, it looks like you are doing some recipe type operations from a button? Try disabling that, and see if the issue goes away. Also, the current version of WW 10 is 10.1 SP2, I think that there was a SP for 10 as well, do you have a support contract?

The System Management Console (SMC), would be the 1st place to start.

Do not bother about understanding the workings inside the FB if you do not understand its function. The 192.168.1.100 would of come from the person that configured the code.

But what about Ladder memory, FB memory is one thing, my point was about ladder memory. Every unique instance of a FB utilises its own amount of ladder memory, as well as FB memory, and depending on design, some FB's utilise quite a bit of ladder memory... I think that we need to explore better implementations of certain functions, such as timers/stored variables etc. I have an idea on how to test this, just no time just now...

So is what I posted beneficial to you? If you need an example, send me a PM, and I will whip something up.

I think that is something they learn on their 1st day, if something resembles a computer, or is a computer running some software, then no-one else knows anything about it. If they want to use our infrastructure, then we know best. This would be one of the reasons that so many automation systems now have their own physical infrastructure, that are managed my the integrator, not IT.

Not to hijack this thread, but this wasn't the Portal product was it?

Are theses daily totals, or something similar? If so, you can use the Filewritefields function, to create a .txt or .csv file, and what ever time you want. You could do it in a data-change, or a conditional. If it is for totalisers, I use a conditional & look at the $Hour & $Second system variables. This way, you can make it reset whenever you want.

Excel is a spreadsheet, not a database. Does you company prefer the information in excel format, as that is what they are familiar with? Would they be happy with a .csv file? This can be opened & then saved as an excel file, and then can have any manipulation/fancy graphs added as they please.

I would like to see some more information on how they save PLC memory? Most times we have used them, the memory usage is quite intense, especially with individual instances or certain FB's. There is the huge extra memory that can now be allocated, but each FB still takes up ladder memory as well..

Hi, From the web server manuals that I have, I have the following part no's listed: Now, I could be asking the most simple of questions, but I am assuming that all the V2 models support the ftp function as well as the Web Server function? So if I had a NS5 with compact flash, I could configure data-logs, and retrieve the files via the web browser of ftp function? We are thinking about automating the ftp function, as this would just make the application for transparent. Any thoughts/extra options/comments?

Post your CX-Designer & CX-Programmer application files and someone will have a look for you.

Instead of using a while , why not just use simple IF statements? Your code could be: The nesting could be improved (if required...), but is this not the same thing as what you are trying to achieve?

Why not use APR, or even a FB, that way you can do everything in Floating Point?

Attached is 1 example, possibly the way I would do it. I have allowed for a separate start/stop variable from CX-Supervisor for each shift, whereas, you may want shifts to roll 1 to the other, then you could use the Shift 1 Finish as Shift 2 Start etc. or, you may want a gap between shifts, so this will allow for that. Hope this helps. Clock_Example.cxp

Perhaps not solved back in 2007, but solved in 2009..... http://forums.mrplc.com/index.php?showtopi...amp;hl=password

Well, Bob suggested a FB! Does that mean that you are slowly coming round to FB's Bob?

Ladder logic would be the easiest Depending if you want control down to the minute level or not, but simple > < type instructions would be the way to go. I think that certain models have the PLC clock Hours/Minutes combined into 1 BCD word, you could do a comparison with this, and turn on the bit as the result. Give it a go, if you can't work it out, post back and we can setup a basic example.

What pfort was trying to point out, is just because a PLC does not have a certain instruction, does not mean that a function cannot be achieved. In the example posted above, does this look that hard to implement? This is basic logic, and is quite easily done with the slightest of effort. Would it not be correct to say, I want a device to stop a certain time after the run command is removed? Whether you use a TON/TOFF/TMIDDLE/TSTOP/TMRPLC should not make a difference....

Next question will be, how do I do a Masked Move...?
