communication with NI cDAQ-9188

[Reg_edit]

Hello,

I wonder if it's possible to etablish a communication between a computer and the cDAQ-9188 station, using the ModBUS over TCP/IP protocol or a Serial ModBUS protocol.

Is there a module to add to the chassis ? I don't find it in the NI CompactDAQ Guide.

Is it possible to directly read the frames ?

The communication to the chassis is via Ethernet but not modbus. You use DAQmx functions to read/write to whatever modules are in the chassis.
