 # IOT2000 GPIO Demo
-This example project shows how to use the GPIOs with CODESYS on a IOT2000 with GPIO expansion module.
+This example project shows how to use the GPIOs with CODESYS on a IOT2000 with GPIO expansion/IO module.


 ## Product description

-In this example a picture gets evaluated via python and the free library of programming functions opencv.
-There are different color circles in the picture, the blue ones are filtered and coordinates of the contoures are written in a string.
-The string gets combined with a string of the current time stamp. This string gets transferred into a byte array and filed on shared memory.
+The small webvisu shows the status of the inputs as lamps, the outputs can be controlled via switches.

-For a selected time the shared memory is open (in this case 60 seconds), to make it possible for CODESYS to read the data.
-In CODESYS the shared memory buffer is read and the byte array is transferred to a string again.
-
-After transferring to string the coordinates of four contoures are in the string such as the time stamp.
-Another prepared possibility is the evaluation of a video stream, the contours in this case are limited to five to get no overflow.

 ## More information

  **Preparations**

-Open "OpenCV_Example2.project" via CODESYS.
-Install Python 3.4 or higher, set the environment variables in Path and install opencv:
-Command line : pip install opencv-python
+Install / mount the IOT2000 IO-expansion module according to its user manual on your IOT2000 hardware.
+Install and run the CODESYS Control for IOT2000 SL on your IOT2000 hardware.


 **Procedure**

-Start CODESYS and connect to local ControlWin and log in, start, etc.
-In monitoring (PLC_PRG.strRead) value of string is "".
-Run python script -> In monitoring string has four coordinates and one time stamp.
+Start CODESYS and open the example project. 
+Download and run it. In the online or webvisualization you can see and control the inputs and outputs.

-**Further functionalitys**
-
-The main functionality of opencv can be looked up on the website https://opencv.org/.
-For more functions the buffer of shared memory maybe must be increased.
