-# TITEL
+# OpenCV Example 2
+This example shows a python implementation of opencv a free library of programming functions.
+With this library a picture gets evaluated and the information is transfered to CODESYS via shared memory.


 ## 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.
+
+For a selected time the shared memory is open (in this case 60 seconds), to make it possible for CODESYS to read the data.

 ## More information

- 
+ **Preparations**
+
+Open "OpenCV_Example2.project" via CODESYS.
+Install Pyton 3.4 or higher, set the environment variables in Path and install opencv:
+Command line : pip install opencv-python
+
+**Folder location**
+
+The python project and example picture should be in the same folder.
+Name the shared memory buffer in CODESYS same as in python (default "MySharedMemory").
+Set the same size for shared memory buffer in CODESYS as in python (default "100").
+The time of open shared memory can be set in python project (default 60 seconds).
+
+**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.
+
+**Further functionalitys**
+
+The main functionality of opencv can be looked up on the website https://opencv.org/.
+For more funcions the buffer of shared memory maybe must be increased.
