Hi, 
I am looking for a paid or free course online for LabVIEW instrument control that covers topic like  communication protocols, RS232. GPIB etc. Can anyone suggest a good one. Thank You.

View File Plasmionique Modbus Master
This package contains the Plasmionique Modbus Master library for LabVIEW.
It supports RTU, ASCII and TCP modes with the following function codes:
0x01 - Read Coils
0x02 - Read Discrete Inputs
0x03 - Read Holding Registers
0x04 - Read Input Registers
0x05 - Write Single Coil
0x06 - Write Single Register
0x07 - Read Exception Status
0x0F - Write Multiple Coils
0x10 - Write Multiple Registers
0x16 - Mask Write Register
0x17 - Read/Write Multiple Registers
0x2B/0x0E - Read Device Identification
Other features include:
- Sharing a COM port across multiple Modbus sessions using VISA locks (10 second timeout).
- Sharing a Modbus session across multiple communication loops.
- TCP transaction ID handling to ensure that requests and responses are matched up correctly in case responses are received out of order.
- Modbus Comm Tester, available through the "Tools->Plasmionique" menu, for testing communication with a slave device without writing any code. 
- Detailed help document available through the "Help->Plasmionique" menu.
Examples are included in "<LabVIEW>\examples\Plasmionique\MB Master\":
MB_Master Comm Tester.vi: Demonstrates usage of API to open/close connection and communicate with a Modbus slave device. MB_Master Multiple Sessions.vi: Demonstrates usage of API to open concurrent Modbus sessions. MB_Master Simple Serial.vi: Demonstrates polling of a single input register over serial line. Download a copy of the user guide here: MB_Master - User Guide.pdf
Note that Version 1.3.4 of this library has been certified compatible with LabVIEW and has been released on the LabVIEW Tools Network: http://sine.ni.com/nips/cds/view/p/lang/en/nid/214230
The most recent version of this library will always be released on LAVA first before going through NI's certification process.

Hello,
I'm currently encountering a problem when accessing FPGA indicator with "Reading/ writing a control" node
The FPGA part acquires data every 10µs
The RT part Read the indicator every 2000µs
But when Running the VIs, I see that the elapsed time between 2 Readings of the indicator change from one iteration to another
Can someone help me?

Hey guys,
 
I'm trying to do some scripting on a Realtime-VI wich uses the FPGA Interface "Read/Write Control". I open a Reference to a VI containing a Read/Write Control, and when scrolling through the BD-Objects I find it with the class-name "nirviReadWriteControl".
I used the "to more specific class"-VI to check wich class i can cast it to, and i tracked it down to be child of the GObject->Node Class. But i can't cast it to any of the childs offered in the class specifier constant.
I also found out, that the "nirviReadWriteControl" is a xnode.
I have never worked with those, is there a way to access theyr methods (I think they're called "abilities" for xnodes)?
 
The goal of the application is to make the Read/Write Control display all available FPGA FP-Elements, and connect Controls/Indicators to them.
 
There is the same Problem with the "Open FPGA Reference"-Node (Classname "nirviOpenFPGA").
 
I really hope somebody dealed with the xnodes a bit and can help me programmatically controlling them!
 
Best,
Trip
