Also a working setup on another PC has both users as system=default.Earlier post: OPC server 2012 cannot connect to Labview 2012 most of the times?OPC I/O Server Diagnostic Information 11:35:19,617I have a simple VI which open's a FPGA Reference (using Open FPGA VI Reference) in dynamic mode, downloads to FPGA and runs it.This is done before a timed loop starts and then the reference out of the Run invoke node is passed to do operations such as read and write.The issue I have is that I have another loop, which is significantly larger visually and the process of passing the reference wires around is a total nightmare. I suceeded to set a named local user for both Component/DCOM and Services/NI OPC, but no improvement. That is now available, greyed out for some reason. People say that I should 'run as interatice user'.

Ni Opc Server 2012 Update Of Control

This vi communicates with the controlling.vi via s ingle-process shared variables and with the user interface via network-published shared variables.A third, Logging.vi is used for logging data and saving them on the PXI. Chart monitoring and update of control setpoints. Also a Networking.vi is used for interaction with the user, e.g. However when I rebuild the FPGA, which changes interfaces I have to delete the control and re-add it, which means all the local references I have need to be replaced.Ived tried using another FPGA dynamic reference, which works fine but puts a 75ms overhead on my loop which isnt acceptable.What is the 'proper' way I am supposed to do this keeping in mind I need to quickest possible update rate.I use a real-time application (see attachment) with various VIs running in parallel on a PXI target.In the Controlling.vi, sensor data are captured and simultaneously actuators are commanded both inside a Timed Loop.

This works well and is all fine and good, but when I started working on my second one I started thinking if I should do a Simulated DAQ as a child (override) of the specific DAQ that it's simulating. My first go at this had a 'Data reader' actor (what I believe is called the 'hardware abstraction layer') which had two child actors, a DAQmx one and a Simulated one, where a window would let the user enter the values. Part of my code involves using various hardware devices, which need a custom simulation option- for example, a popup where a user can manually enter the values for an analog input.What I'm wondering now is what the best practice would be for simulated hardware from an LVOOP standpoint. Should I use a separate single process shared variable and basically capture the data twice or can I read the same variables that are used for communication with the networking.vi? I am not sure if conflicts can arise due to the fact that one variable will be read from two separate VIs simultaneously.I have a problem getting my hardware recognized when using Labview NXG.To be clear, i've tried a bunch of things to make it realize it is well plugged, but nothing has yet worked.The devices i'm using are present in MAX:And i'm able to detect the captor and visualize the output from the MAX test pannel, however i cannot reproduce it using Labview NXG:Here i only get the computer and the NI PCIe-8361 which is not used in my case.At this point i guess this error is related to the DAQmx driver not working properly with Labview NXG, however i can't install any updates / driver with the NIPM, i always get this error : Server has closed the connexion prematurely:I've also tried to install DAQmx from direct download, but it does not look like to have changed anything (I've seen a thread talking about a Labview NXG DAQmx related driver but I can't find anything looking like that online)If you need any additionnal translation from the screenshot, just ask for it and i'll translate it in englishOther things i've already tried at this point:- Full uninstall, re-install (from the USB key packed with the hardware)Thank you for your help and excuse me for any English errors, it's getting late here and i'm getting really upset about these problemsI'm just now getting started using the Actor Framework and am coming up with some 'architectural' questions I hadn't really considered beforehand. My question is how should I log variables that are already used in the controlling.vi.

Is that easy enough then to feed into a TDMS writer?Would Frame Input Single-Point mode be better so I could sample all CAN messages at a set interval (instead of just having them come as and when, obviously on a vehicle CAN messages are transmitted at different rates, usually dependent on how important the message is).Many thanks in advance for any advice proffered. That, according to the manual, would look like it would spit out an array with msg ID, time stamp, message payload etc. Dbc files so want to log the CAN messages anyway (undecoded if you like) and decode them later when we do get the dbc.From what I can gather you set up the NI 9862 module in MAX and you can assign alias's and things and then you refer back to this set up from the VI you make.In the VI do you go for creating a session (so Frame Input Stream mode session) and then wire that on through to the XNET Read.vi (CAN Frame).
