Step 5 Checking Operations with the Diagnosis
Program
Use the diagnosis program to check that the board 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 board 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 board,
I/O status, and interrupt status.
Check Method
The diagnosis program tests the board actually connected to an external device to check whether count
values are displayed correctly and whether signals are successfully turned on/off. See the following
section about how they are connected.
Connection diagram
Use the following connection to connect the rotary encoder to the photo coupler isolated input. For the
details on the example connection of input and signal position, see Chapter 3 "External Connection".
* If you apply a 12V external power supply for this test, the resister R should be about 400
Ω
.
. However in case of 5V power supply, the R is not required.
