<div class="markdown_content"><p>It would appear that PlcHadle.dll can only be used by having the SDK. However, it would be very interesting to be able to use it even without it, as it would open the way to unthinkable levels of integration.<br/> Today I go around it with shared memory. In this way we interface a big framework that we developed in Qt through a gateway in shm, however being able to use the PlcHandle would simplify our life a lot.</p></div>

<div class="markdown_content"><p>Hi Forum,</p> <p>I want to connect and make some communication with PLC runtime (v3 and v2) by Python without via CoDeSys v3.5.x. As you known, there are a SDK package with the name of "PLCHandel.dll". I am no familiar with this SDK. So may be same example scripting will make big help to me. For example: start to establish communication between Python and PLC runtime, read FW version, check working state of PLC etc.</p> <p>Thx for any suggestion!</p></div>
