Connect a CMD600 charge amplifier in TCP/UDP with LV2009

[DavidL]

hi there,

I 'm triing to connect an HMB CMD600 charge amplifier using LAN with TCP/UDP.

Should i use, the standart Open/Read/Close TCP functions or UDP or something else?

How can i know or set the IP or port to listen ?

I 've got 2 amplifiers to connect simultenaously, is it possible ? with a switch or with 2 wires from 2 LAN ports ?

And last one : What s the maximum frequency of aquisition ?

Sadly, i dont have access to the amplifier to test anyting.

Thanks a lot

I m' calling for help again.

I'm going to my client next week, and still no idea how to connect TCP/UDP product in labview despite all my googlizations...

anyone ?

thanks

David

Hi David,

I advise you to have a look at the following links, there are a lot of examples and tutorialon the ni.com website:

TCP/UDP LabVIEW 2009 Help 

TCP/UDP examples on ni.com

TCP/UDP Tutorials on ni.com

Kind regards,

[DavidL]

Thanks for the links.

Do you have any informations on the response time / possible frequencies and actualy if it 's a viable way to do such an acquisition  and synchonise it with other signals from the PCI6220 ?

Thanks.

Best regards

Hi David,

I don't really understand what you mean about synchronizing PCI 6220 and TCP communication.

The TCP reaction will depend of a lot of factors as your network card, your CPU Load, the way you programmed your diagram...

I can't say if it's viable because I don't know what you need to do exactly.

hi,

I've got 5 position sensors (TTL mode ) plus those 2 force sensors, and i 'd like to know simultaneously the value of these sensors during a few seconds at a 1k acquisition.

Iv'e tried 2 UDP vi, but i dont know wich port to listen.

Thanks Olivier.

Unless you don't run a real time protocoll like Ethercat, I see no chance to sync your measurements between the CMD and your PC.

To synchronize the measurements I only see two options:

1. Use the analog output of CMD600 to measure it with the 6220. + avoid the ethernet - one more channel of the 6220 needed

2. It seems that the CMD has DIOs , use an DO to trigger your 6220 aquisition OR use an DI to trigger the CMD with your 6220. Then read the data via the network.

Have you asked HBM if they have a LabVIEW driver? Or a dll to control it, you can call with LabVIEW?
