still can't get realtime temp logging

[Sloppy]

I have been trying to get a chart showing temperature vs real time of the measurment, for example temperature vs the time (hh:mm:ss) of the measurement

All my graphs start at 7 am 1903. I have seeded the XScale.minimum and XScal.increment properties in the properties node for the chart with the start time of the measurment run. when I do that the x axis initially has the correct real time scaling, but my data does not appear. Only when I check autoscale x axis does my data appear, and then with the y axis at 1903 again.

How do I tell the chart to use the real time of the measurement on the y axis? Using fp2010 with temperature modules and fpread.vi

thanks again

Hi Sloppy,

This is just a guess. Are you using waveform datatypes? If, so you must make sure t0 is set correctly before presenting it to the graph (i.e. 7 am 1904 = 0 in LV time).

Otherwise post your VI and we may be able to give you other ideas.

Hi Ben, thanks for the response, and this is directed not just to you, although I certainly appreciate your time.

I'm REAL new to LAbview programming so keep that in mind.

I have several problems to deal with, but one thing at time.

I've included a VI which constantly reads temperature from my FP hardware, only a single channel at a time(one of the problems) and will set the x axis to the current time date at the start of the run, but the data being recorded doesn't appear on the chart unless I "autoscale" the x axis on the graph, and then the data displays with the x axis at 1903. Thats the problem that prompted me to find you guys and seek out tech support.

However, I have other issues with the FP stuff that I'm hoping I can get support for here

Here is a biggy:

When you look at the vi I posted you will see that unlike the Example FP Temp.vi, I found I had to put the Open, Create, Read and Close all inside the loop because if I didn't then the temperature reading I got from Read never changed after the first reading. I realise this is likely adding overhead, however I found I had to Close the FP stuff and redo the Open/Create sequence in order to ensure I got a "fresh" reading from the Read command. If I didn't the reading I got from the Read.vi never changed after the first reading. I didn't get any errors, I just didn't get any new info from the Read.vi

What I'm saying is I never could get the FP Temp Example to work with my hardware., but this vi does work in so much as it reads a new temperature everytime through the loop. Any comments on that would be appreciated.

I'm using FP 2010 with two FP-TC-120s, an FP-RLY-420 and an FP-0A0-210. However at the moment I'm only using (or trying to communicate with) one of the FP-TC-120s, but all of the modules are connected togethor and are showing me POWER/READY indicators. Power up self test appears normal as per the manuals and I beleive the hardware is working nominally.

PC is a windows 2000 pro 866 mhz connected to our 100 Mbps intranet through a hub to which the FP-2010 is also connected.

I have lots of other questions. One I will ask now is where do I find documentation on all the Property node properties for all the controls and indicators. When I go to select properties for a property node on something like a waveform chart there are hundreds of properties listed in the menus. Are these documented somewhere and if so where?

sorry for the length and I appreciate any and all responses.

thanks again.

Verify that you have the FP-2010 synchronized to a Logos Time Server. This can be done in FieldPoint Explorer by right clicking on your comm resource and selecting "Edit this comm resource" and browse to your FP-2010. Once you see your FP-2010 in the Remote System Explorer, right click on it and select "Configure device" and go to the "servers" tab and set the Time Server IP address to a machine that has FieldPoint Explorer installed on it.

Thanks Chad

I've done all that, however I get an error about not being able to look the correct DNS address when opening Remote System Explorer. However, my FP-2010 shows up at the proper IP address and the time server IP is set to my Win2000 PC running Fieldpoint Explorer.
I will talk to my IS people right now about this DNS error


Thanks Chad
