i'm using CompactRIO to calibrate 20 electronic meters (counter) in parallel.
*CRIO FPGA to communicate with:
---> 20 meters in parallel: 20 UART(RS232 or Ethernet).
---> 1 generator: 1 UART(RS232).
---> 1 standard meter: 1 UART(RS232).
---> 1 automaton: 1 UART(RS232 or Ethernet).
*CRIO RT for calculations ( floating point),adjusment and verification of 20 meters in parallel.
Please who can help me in the development (how to start) of this application, then we will go into details

It sounds like your application is going to need to have 3 main components: A Host VI on your computer, an RT VI on the cRIO, and an FPGA VI. For getting started, you may consider looking through the following documentation:
LabVIEW FPGA Module Training
Getting Started with the FPGA Module
If you're already familiar with the basics then you may consider starting with an example from the LabVIEW Example Finder. From LabVIEW, select Help >> Find Examples. Then select Hardware Input and Output >> CompactRIO >> FPGA Fundamentals. From here you can look through examples more specific to your application. Hope this helps!

Since this thread has been marked "Solved", the forums do not generate a follow-up task for the AEs. To ask a new question, visit the appropriate forum board, such as Real-Time Measurement and Control and click New Message. Generally, you'll have better results posting your own question to your own thread, unless it's directly related to the first post on an existing thread that hasn't been "Solved".
The examples you're looking for are available in the location you've identified after you install support for the cRIO platform. Visit this page to determine the software necessary to support your cRIO.

if you cant find CompactRIO that means the necessary toolkits arent installed. Install LabVIEW FPGA toolkit and LabVIEW RT toolkit... then you will find the path specified by the Application Engineer before ! If you still dont find it, check if the NI RIO Device drivers are installed !!
hope this helps !

You can read the serial ports, from a C Series serial module, in either RT or FPGA. If you access the serial port through the FPGA directly then you have to rebuild the serial signal bit by bit. A good example of this can be found here:
RS-232 Interface Reference Example for LabVIEW FPGA
However, for most common applications it's easier and makes more sense to simply access the port from the RT side. Hope this helps!

could somewone try to help me??
i need also a vi called `Sample Rate to Loop Time.vi`, he has a polimorphycal behaviour .
cold somewone send me or atach this file ??

This function is included with the FPGA module. Do you have that installed? Here is the help document for that function.
