 8 | [CODESYS Program](https://github.com/Pi4IoT/CODESYS_Serial/blob/master/Pi_Serial_FB_10.project)
 9 | <br /><br />
10 | This example demonstrates how serial communication can be implemented, how ports are opened, 
11 | closed on Raspberry Pi to communicate with Arduino via COM Port RS232 by using CODESYS.
12 | 
13 | The Demo set the light of the LED bar and read out the temperature from the thermocouple.
14 | 
15 | First of all you need to download the free The CODESYS Development System (you need to register) after install it, 
16 | you need to download CODESYS Control for Raspberry Pi SL (free version  runs for 2h and the you need it to restart)
17 |

21 | 
22 | ## Important
23 | After install Codesys on Raspberry you need to edit the file “CODESYSControl.cfg” as following:
24 | sudo nano /etc/CODESYSControl.cfg 
25 | <hr>
26 | [SysCom]<br />
27 | <br />
28 | Linux.Devicefile=/dev/ttyACM <br />
29 | portnum := COM.SysCom.SYS_COMPORT1<br />
30 | <br />
31 | <hr>
32 | Save it and restart the codesys controller <br />
33 | sudo /etc/init.d/codesyscontrol restart<br />
34 |
