I found a snippet of the deleted NI document in a thread of mine at a German Forum. http://forum.gsi.de/index.php?t=tree&th=72...67561159142e672 "On Windows, you also can copy the attached DLLs to your browser directory. For Netscape 6.x, copy NPLVWin32.dll to the ...Netscape 6\plugins directory. For Netscape 4.x, copy the same file to the ...Netscape\Communicator\Program\Plugins directory. For Internet Explorer 5.x, copy LVActiveXControl.dll to the ...Internet Explorer\plugins directory." I copied the NPLVWin32.dll into the plugins directory of firefox. The ugly thing was: first uninstall the RunTimeEingine and reinstall it again. ... and it works. Manfred

NI provides a free, downloadable set of VIs for Modbus communication under http://sine.ni.com/nips/cds/view/p/lang/de/nid/201711 I think it will be part of PDS and supports RT. Up to now there is little documentation available. I've tested Modbus TCP/IP connection with WAGO-I/O-750 and it works. For us it's a great progress compared to OPC talk. Manfred

Problem: Writing to the cursor position property does not update the position shown in the cursor legend. What can I do to update the cursor legend? Solution: There is a known issue which causes the cursor legend to not update properly when writing to the Cursor->Cursor Position->Cursor X and Cursor->Cursor Position->Cursor Y properties. As a workaround, to update the legend you can run the VI again or write to the property node twice by putting it in a for loop that executes twice. Alternatively, you can use the Cursor List property to programmatically change the cursor's position. Manfred

Peter, have a look at SplineInterpolant.vi it will calculate the second derivatives for you. Boundaries can remain to default with your data. Manfred

Jack, please just answer a simple question: Are you working with absolute or relative time in your Waveform Graph? Greetings Manfred

Jack, numeric cenversion palette contains a "To Time Stamp.vi" that converts a number to a time stamp. You don't have to make the string conversion. just my :2cents: Manfred

Your question will be answered by http://digital.ni.com/public.nsf/allkb/93D...6256BE6006FB868 Greetings Manfred

I guess you need a conversion from binary to string. 01010101 is the binary representation of "U". See details in program snippet attached. Greetings Manfred Download File:post-831-1113894166.vi

In win95 and win98 days one had to install Remote Registry Services. http://digital.ni.com/public.nsf/allkb/862...62567660047D840 Is 4) a machine with XP and 98 installed on it? Just :2cents: Manfred P.S. There are a lot of hints at NI. http://search.ni.com/nisearch/nisearchserv...stry+service%22

Merlin, if you need static images on your front panel (??) simply copy and paste them out of the Explorer. Greetings Manfred

just :2cents: try this: http://www.air.nl/nlibrary/modbus_vi.html Manfred P.S. Sorry it's just for serial devices

Andreas, you can't name a wire, but you can name it in Bundle by Name Function. Manfred

Sorry reading might be OK - but don't write to RTC For more details see: http://digital.ni.com/public.nsf/3efedde43...bd?OpenDocument Manfred

A snippet of my post to info-labview Date: Wed, 7 Jan 2004 09:47:54 +0100 On PC-machines the one and only real information about time is available on RTC-CMOS. You can read this information by OutPort and InPort conversation from any language. Everything else is hickhacked by OS and software. OutPortAddress = 70h InPortAddress = 71h WriteValue DataRead 00h seconds 02h minutes 04h hours 07h day 08h month 09h year No lability on this information. You will communicate down to CMOS! You can also write to RTC-CMOS Sorry I can't find the VI at the moment. Manfred :2cents:

Dear list, in ...\LabVIEW...\vi.lib\instr\_sersup.llb you will find additional VIs for serial comm. With "windows Flush com buffers.vi" transmit and receive buffer can be cleared separately. It's a Windows specific VI. May be its the reason NI hides it from functions palette. Greetings Manfred

Sorry RGB to Color.vi might not be available in Version 6.0 Search: or follow this http://www.sullutions.com/LabVIEW.html#ColorPalette Geetings Manfred

In order to change color ramps of an intensity chart you have to wire color table in property node. For color definition have a look at "RGB to Color.vi" Greetings Manfred :camera:

Bryan, LabVIEW help note for replacing block diagram objects may give a hint: "Note When you select a VI with the same name as a VI in memory, a dialog box prompts you to replace the VI or cancel the operation. If you select Replace, LabVIEW replaces all the VIs in memory with the VI you selected." Before following this note you should save old VI with another name. Greetings Manfred

Use "Scan From String" function.

There is a nice Color Palette on http://www.sullutions.com/LabVIEW.html or have a look at "RGB to Color.vi" from the Picture Functions palette. A "Framed Color Box Constant" makes more sense and is better understandable than numerics. P.S. Thanks for praise - I just realized a suggestion from another forum.

Put all your data in one plot and make those invisible which are not relevant at the moment. Use transparent colour for this purpose. See :camera:

Have a look at this thread: http://forums.ni.com/ni/board/message?boar...y.id=5602#M9530

Goetz, probably the cursor is locked to the waveform. Unlock it by right click on the lock and choose free. Manfred

Have a look at the Knwledge Base http://digital.ni.com/public.nsf/3efedde43...09?OpenDocument Manfred

Possible reason(s): LabVIEW: Duplicate path. --- NI-488: New I/O attempted with old I/O in progress. Sounds like file is not closed?! Manfred
