Step 4 Checking Operations with the Diagnosis
Program
Use the diagnosis program to check that the product and driver software work normally, thereby you
can confirm that they have been set up correctly.
What is the Diagnosis Program?
The diagnosis program diagnoses the states of the product and driver software.
It can also be used as a simple checker when an external device is actually connected.
Using the “Diagnosis Report” feature reports the driver settings, the presence or absence of the product,
I/O status, and interrupt status.
Check Method
To check the analog I/O data, use the loopback connection on the board to directly connect the analog
output (channel 0) to an analog input, or connect to an external signal source.
No external connection is required if using loopback to check the I/O.
The figure below shows an example of checking by connecting to an external signal.
The example is for channel 0 on the product.

Input data remains indeterminate when no input pin is connected. The input pin for the channel not
connected to the signal source must be connected to the analog ground.
For details, see “Chapter 3 External Connection”.
