<div class="markdown_content"><p>Hi <a class="user-mention" href="/u/fixstuff555/">@fixstuff555</a> </p> <p>I have a smart home project. I did for this project that connecting between arduino/ethernet shield and raspberry with modbus tcp in codesys. But I need to do this project with wireless. So I had a ESP8266. But I didn't know arduino code. Can you help me ?</p></div>

<div class="markdown_content"><p>Modbus is your friend. Its the best way that I have found to get external data into and out of Codesys.</p> <p>Just add the relevant library into your application (C, Python, etc), and just send data from a client (your code usually), into a Modbus slave running in Codesys. I've done this with C, Python, and Node-Red and they worked just fine.</p> <p>For example, I had an Adafruit Ultimate GPS board plugged into the Pi. I used Adafruit's sample code, and just added the Python Modbus library, and sent position data over 4 registers into Codesys.</p> <p>For the Node-Red, I simply added the Node-Red-Contrib_Modbus library, and was sending data to and from Codesys from Grove Sensors (also added via Node-Red library)</p> <p>I've also used Modbus from Codesys into ESP8266 modules. This was using the Modbus libraries available for Arduino. I could pass all the IO of the ESP8266 (an Adafruit Huzzah actually), and use it as a generic remote wireless IO node.</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> scott_cunningham</p> <p>The module was at one time available for everyone but now only to their OEMs (implies not easily implemented/issues/etc). Many people have asked - nothing has been offered up. You may be better off setting a GPO (general purpose output) that your other code is watching for.</p></div>

<div class="markdown_content"><p>Hello,<br/> I have found mostly dead links or hopelessly outdated information in regards to my problem. Hopefully anyone in this forum can advise me. I want to inject native code into my structured text. I do not care whether it is C, Python or whatsoever, I just need to find a way to embed "external" functionality into my CodeSys Program running on the Raspberry.<br/> And yes, I have found this module provided by CodeSys that matches this very purpose, but it is geared towards device manufacturers. It is not geared towards the average joe end user. </p> <p>Thank you in advance for your time to respond to this thread.</p></div>
