<div class="markdown_content"><p>Yes,<br/> might possible, but not out of the box.<br/> Currently we are missing some components in the PI (to use the Pi as CODESYS - CAN Gateway to login)<br/> - using Android is not possible at the possible not realized at the Moment.</p> <p>So I could not really help at this point.<br/> Guess you need to contact 3S - and official inquiry is needed.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi Edwin,</p> <p>again, thanks for your fast reply, and my apologies if I was not clear in the goal of my project. I will try to better describe the system.</p> <p>Our PLCs are CAN-based and we need to access to these PLCs remotely (through the internet) from a Windows PC with CodeSys in order to see/change/update variables and download the software of the PLCs. At each PLC we will use a "gateway" based on an Android App (_ or Smartphone). This "gateway" will be the interface between 3G/4G (TCP/IP frames) and bluetooth, and finally we will use a bluetooth to CAN adapter attached to the CAN bus of the PLC.</p> <p>Would this be feasible?<br/> Regards</p></div>

<div class="markdown_content"><p>Hi,<br/> what is your real goal?<br/> 1. Use a gateway to see/change/update variables in your CAN based plc?<br/> 2. Login by CODESYS to the CAN based plc (via CODESYS Gateway)?</p> <p>-Sure the Raspberry Pi contains a CODESYS Gateway and you could use it for 'Login' to another plc (CAN or TCP/IP / UDP).<br/> -Login via CAN might possible, if you manage to run a socket CAN on the PI (but I never tried this - not sure if this will work reliable...)<br/> -Sure an OPCUA Server is embedded in Raspberry PI too and you could use it to access symbols from the CODESYS application (which is running on the PI)<br/> If you connect the Pi Application by CAN (in that case CANopen Master ) to the second CAN based plc.. yes it is true you could use OPCUA<br/> to access your CAN-Based second plc (act in that case as CANopen slave).</p> <p>really confusing without having a system overview.<br/> hope i did not confuse to much with that <br/> BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hello Edwin,</p> <p>thanks for your response. I have seen that the Gateway server can only run on Windows. Unfortunately, our gateway should run on Linux or even Android, therefore, the Gateway server software is not a solution yet.</p> <p>What about the CodeSys Control for Raspberry PI? Could we use the Raspberry as a gateway by running the CODESYS OPC/UA Server on the Raspberry PI? how should we connect the Raspberry to the CAN based PLC?</p> <p>Regards</p></div>

<div class="markdown_content"><p>Hi,<br/> I thought on using the Gateway which is running on a pc.<br/> See the tasktray Icon to start it.<br/> This is available as standalone setup to install</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: Gateway.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1362"/></p></div>

<div class="markdown_content"><p>Hi Edwin,</p> <p>you proposed to use a gateway and connect it to the CAN network with an USBPeak-Dongle. Which gateway do you recommend?</p> <p>I would like to build a custom gateway based on a 4G SmartPhone. Is there any Android App ready that can communicate using TCP/IP with CodeSys Control Win on my local PC. Would this be feasible?</p> <p>Regards</p></div>

<div class="markdown_content"><p>Hi Edwin,</p> <p>thanks for your fast reply.</p> <p>I understand that for that we could use a gateway connected to the PLC. That is an elegant solution. However, we would like to use our TCP/IP to CAN interface instead of the gateway.</p> <p>Is it feasible? How should I connect CodeSys to the interface DLL? The DLL will encapsulate/de-encapsulate the CAN packets from/to CodeSys into/from TCP/IP frames.</p> <p>Regards</p></div>

<div class="markdown_content"><p>Hi,</p> <p>should not be needed to write a dll this is for sure.<br/> Just use a gateway on remote side, and connect this by USBPeak-Dongle to your CAN network.<br/> But I would prefer to Login by ethernet to the plc and then use CAN Network for the sensors only.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hello,</p> <p>we would like to use CodeSys v3.5. Regarding the PLC, we still did not select any specific PLC. It will be a PLC interfacing to sensors/actuators through CAN bus. In order to connect the PLC remotely to CodeSys, we have foreseen to use our CAN to TCP/IP interface.</p> <p>Regards</p></div>
