I wanted to try NXG with my existing cDAQ-Equipment and ist did not work.

Reason NXG can not handle LAN-Devices in the Network.

So i still used Labview the old way.

How much data are you transferring? For example, if you are reading 1000 input registers, one register at a time, then you can't expect to get a sample rate of 100ms.

=> The maximum registers I had were about 50. I do not want to have a fast sample rate as I have slow changing processes, but I like to synchronize (have the same samplerate)  the data derived from Modbus with my DAQ data. 

Screenshots or sample code would be useful if you are looking for help.

=> is attached

Are you using the Modbus Comm Tester?

=> no

I have attached the VI that I use tu read the registers. 

Modbus Read Waveform.vi

Thanks for the easy to use Libary.

As I have a combined measurement, a NI-DAQ-Device and the DUT, that sends its internal parameters via Modbus, I would like to set a sample rate for the MODBUS data and to synchronize both systems

The Baudrate is at the moment at 230400, but data are flowing in with samplerate arround 1sec.
