Cfp-2120 serially trasmit IO module data

Question

We have a  cFP-2120 with AO, DO, DI, and AI modules connected.
All work fine.  Using Ethernet communications.
Can apply a voltage on the AI and do a FP Read ala the example Analog Input.vi
Receive expected measurement.
Curious if its possible to alternatively do this with a serial connection.
Can I send an FP Read through serial connection and read back the resulting IO module channel value through the same serial connection?

Answer 1

Wes_OH - the FP-100x (As well as the cFP-180x) are not "intellegent" controllers, meaning you cannot run LabVIEW RT on the controller.  You read data from the 100x to your PC over a serial connection.  The RT controllers (like your 2120) do not send data over the serial port, they publish their I/O over Ethernet.  The serial port on the 2120s are available so your embedded application can utilize the port for serial communication, it is not intended to be used the same way as a FP-1000 or cFP-180x serial port.
You may still be able to use the FP-1000 application with your 2120, it depends on how the FP-1000 application was written.  Is it a LabVIEW application?  Is it using the Optomux VIs to communicate with the 1000?  Or is it using the FieldPoint Write and Read VIs?  If you are using the Optomux VIs, then you cannot reuse the application because the 2120 does not have a Optomux server running on it.  If you are using the FieldPoint Read and Write VIs, then there is a good chance you can reuse that application because those VIs support Optomux (over serial) and Ethernet communication (for the 2120) depending on the I/O Point you are trying to communicate with.
