Data exchange with non-QNX computer

Hi!

Could someone point me?

We need to exchange data from our QNX with outer world. Common task,
isn’t?)))
I’m looking for some wide used, SIMPLE and WELL documented protocol to
transfer data to a foreign system (the wind-s in fact).

Modbus RTU/TCP is one of that, but it is not that one :slight_smile:

I’d like to find smth with TCP/IP as transport level,
possibility to describe data blocks,
documented read/write requests
and widely implemented on several platforms.

Is it possible? But don’t say that “it is OPC”, please! :slight_smile:

Thanks
Oleg

Try SPREAD, it is highly portable middleware. PVM (at
www.sf.net/projects/openqnx) could also an alternative.
PVM works with different operation systems.

If you are interested … I could send you Orbit 2.0 for QNX6.

Thanx. I’ll try both.

In fact, we are looking for some “standard de facto”,
widely used in SCADA systems, and rather simple to realize )))
The main problem is how to download various types of archive data
and represent them on non-qnx side.

No, thanks. We use QNX4 still.

Here are 2 suggestions.

  1. ftp. There are several means of implementing this simple file
    transport tool from the MS Windows side (e.g. see www.ipswitch.com)

  2. Samba. This allows direct file visibility and sharing within a local
    area network. (www.samba.org)

I’ve encountered some problems with each as applied to QNX 6.2.1 attached
to a network of Windows XP PCs – mostly centered around
privilege/permission issues compounded by inexperience with QNX 6.

…sorry for the slow response, I just browsed this area for the first
time today.
