FP-1000 on serial port of PXI-8175RT?

[Ennio]

Can I communicate a PXI-8175RT (running an application in RT OS) with a FP-1000?

Ennio,

The answer is yes, you may use a PXI-RT controller to communicate with FieldPoint serial modules. However, there is a difference in how you program the communications. Instead of using the FP Read.vi, FP Write.vi etc... you need to use the FieldPoint Optomux VI's. These are a lower level driver that is specific to FieldPoint Serial Modules. For an understanding of the commands, take a look at the FP-1000/1001 Programmers Reference Manual. The Optomux VI's will be installed from FieldPoint Explorer 3.0.0 or later by default only if LabVIEW RT is on your system. Alternatively, they can be downloaded from the ftp site at: ftp://ftp.ni.com/support/fieldpoint/LVFPOpto/

I recommend that you first configure the FP-1000 bank on a Windows computer as using F
ieldPoint Explorer to configure the modules is easier than programmatically configuring the modules.

Thanks for your help. I will try to explain my application (my english is poor). I want to run an application in a PXI8175RT controller with a PXI-4472 board, plus a FP-1000 with a TB-10 module (3 FP-AO-C420 and 1 FP-DI-AC120). This board take 8 ICP mic's signals making a real-time analysis of 5 seconds duration. When finish the analysis, the application must read a digital 120 VAC signal, sent by de DCS (distributes control system of the plant), and must send 3 4-20mA signal to the DCS.
I never has used a PXI or LabviewRT or RT OS (only Labwindows with NI DAQ Boards), so I appreciate comments on this application. I know that I can make this application using a FP-20xx, but it use the Ethernet port and is more expensive (I need one port for the in-site serv
ice and I understand that the RT OS only can work with 1 port).
Thanks for your time and help. Regards,

Ennio

Ennio,

Since you are new to LabVIEW, I would recommend that you consider some of the LabVIEW and LabVIEW RT training courses/materials available from NI. They will give you a very solid foundation to start with. My knowledge specialty is FieldPoint, so that is the area that I will provide pointers for.

From a programming point of view for the FieldPoint component of this system, you will need to use several of the FieldPoint Optomux VI's. You will specifically need to use the (!K) Read Discrete With Status.vi or (!J) Read Discrete.vi to read the state of the FP-DI-AC-120. You will use the (!H) Write 16 bit.vi or (!I) Write 16 bit with status.vi to write to the FP-AO-C420's.
