LabVIEW Server

[TerraNova]

Have a nice day, guys!

Our company has pointed very interesting question to me:

What is the best platform for running LabVIEW application on twenty-four hour basis (including file I/O and signal I/O)?

1. Windows (XP/Server)
2. Linux (Red Hat)
3. PharLap(LabVIEW RT)

The highest features are Reliability and Stability.
Any advices and, especially, experiences are highly appreciated!

Thanx in adv!

P.S.: And what is National Instruments "official opinion" 'bout running LV app as a Server app?

In my opinion LabVIEW RT would be the only option if you truly needed 24 by 7 uptime. I have used RT on critical control systems that had to be up for months at a time running data acquisition, PID loops and user interface with host PC.

Thank you, Buddy!

Any more opinions?

Thanks.

In regards to your Post Script, do you mean running a LabVIEW application off of a network server?
If so, I do not believe this would be recommended; for instance, LabVIEW is not supported on Windows Server 2003. If this is something you would prefer to do, you might consider the Volume License Manager.
Let me know if I've misunderstood.

Hi, Emilie.

For now, technical issues are the following:

1. System with RS485/RS232 ports should work 24 hours a day 7 days a week (that's why I named it "Server")
2. Ambient temperature range is as wide as possible (including negative Celsium temperatures, if possible)
3. It should have HDD in order to make data backups and archieves
4. No graphics is needed
5. Maintainance is one month or one week often (with notebook or Palm)

LabVIEW application should read date from one RS485, then prosess and backup data processed, then send it to another RS485 (or RS232).

What platform (hardware + software) can NI recommend?

Thanks.

Hello Sharonoff,

I would say that any of our Real-Time targets would be ideal for this kind of application. This includes our PXI, cRIO and FieldPoint controllers. I believe that if you are doing serial communication, I believe you can get away with using a FieldPoint controller (most likely the cheapest solution). However, if you are doing some complex signal acquisition with any sort of signal conditioning, you may consider our cRIO or PXI controllers, as the I/O modules associated with these are much more robust.

I think you best bet is to talk to us directly. We have an several technical sales representatives that are more than happy to flesh out your solution with you and provide you with pricing information unique to your profile.
