how to save the dynamic data from a pressure sensor

[YaoYao1]

Hello Everyone,

We have a FPGA board NI cRIO-9073, a temperature module NI 9217 and a pressure module NI 9203. Right now we have problem with saving the data from pressure sensor.  I succeed in getting and saving the data from the temperature sensor. Then I just simply modify the FPGA VI and host VI of the temperature function block which are shown in the attachment files.But I get an error saying I cannot connect two different data types.

Could anyone here give me a help on this?

BTW: we are using a 2 wired pressure sensor with 4~20mA. The brown one is +Vcc and the white one is GND.I connect the white one with the COM of NI 9203 and the brown one is connected to AI7. DidI make a right connection?

Thx for any help from anyone!

What are the "different data types"?

Hi, I get this error message:

Write to textfile: function contains an unrelated or improper connection.You have combined two different types of connections among each other.
At least one entrance of the function required for their operation, is open or not properly connected, the connection scheme is illustrated in the context help.
They have combined two different types of connections with each other. This connection is not possible because the data types (such as "numeric", "String", "Arrary" or "clusters do not match"). Open to see the contextual help at what must have a data type for the connection. The type of data source (fixed) costs. The type of data is dynamic data.
