<div class="markdown_content"><p><em>Originally created by:</em> Nicolai_Hanssing</p> <p>When you talk about HMI, I assume its not the built in HMI?</p> <p>If not then a solution is to use a CoDeSys gateway installed somewhere. </p> <p>CoDesys then has a OPC-server using the symbol-file that connects towards the PLC using said gateway. So our application would use OPC.</p> <p>Other field-busses may offcourse also be used if supported by your target/HMI.</p> <p>Lastly you could use the CoDeSys protocol to communicate directly to the PLC. I dont now if theres a document or any sotware components available for this?</p> <p>Regards</p> <p>Nicolai Hanssing</p></div>

<div class="markdown_content"><p>I'm trying to find out how to interpret a symbol file created by CoDeSys.</p> <p>I'm working with our local Beijer HMI office to try to get them to write drives so I can import a symbol file in the HMI and have access to the variables in the PLC.</p> <p>I know I have done this with the Moeller HMI's and their X-Control PLC and also with the Bosch Rexroth HMI and IndraLogic PLC.</p> <p>Does anyone know how this is accomplished? Is is a form of OPC? Is it straight DCOM messaging? Or something else...</p> <p>Thanks,</p></div>
