I've tried datasocket, too limiting. Tcpip - there's got be a higher level than that. Shared network variables - daunting in complexity and still proprietary to NI. I found 0mq or zeromq the other day, which ticks a lot of boxes. I've written an Excel based test executive but wanted a robust and simple interface to control distributed slave instrument apps. It prototyped ok in datasocket if it wasn't for the fact that controls all appear as integers whatever their real type before they are written to. This makes auto-discovery of resources a pain. I don't see any discussion of zeromq on lavag, has anyone got experience of using the labview version - http://sourceforge.net/p/labview-zmq/wiki/Home/ ? It would be comforting to know it had proved to be reliable and scaled ok before spending any more time on it. I'm encouraged by some prototypes i've written for fault tolerance. Would welcome any experience with 0mq and other suggestions for simple networking without going completely back to basics. Cheers bob, uk
We found this bug when updating from 2010 to 2012 last week. Certain types of clusters will not update over datasocket or network-published shared variable. You will only get their default data. Here are the conditions that will cause the problem: The cluster contains an array of clusters The array of clusters is not the last item in the cluster The array of clusters is empty All three conditions must be fulfilled in order for the bug to appear. An AE was able to reproduce it and it has CAR #385089.
DSC and DataSocket
mike5 posted a topic in Remote Control, Monitoring and the InternetHi all, I'm starting using the DSC module, and since it has it's own shared variable data type, I'm forced to use DataSockets for reading and writing data. So, the DataSocket Read function has a "connection in" interface. This can take (among other things) connection reference from DataSocket Open function, or a DSC Shared Variable wire. If I use the latter, is the connection closed implicitly, or what? And if this implies Open/Read/Close how much overhead do Open and Close this bring? Thanks for any insight. Br, Mike
