<div class="markdown_content"><p>Hi, KevinR.</p> <p>Thanks for interesting information.</p> <p>But, to say honestly, it's not solve my problem.<br/> I say about "Ethercat Master" as example.<br/> Yes, "IoDrvGetInfo" works for Ethercat Master, but it gives incorrect version for Modbus Master (3.0.0.0 instead real 3.5.10.3).<br/> Furthermore, it not works for Modbus COM, Modbus Slave, Ethercat Slave, etc. (I also check method GetDeviceInfo, but it does not contain device version).</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> KevinR</p> <p>Hello e.kislov,</p> <p>This is what I've found out after some research: </p> <p>The information for the device is read from the device description (dd) file. In the dd file, there can also be specified text translation for the info section. So I think, this text is not loaded to the runtime.</p> <p>After some deeper analysis, I've found out that the EtherCat_Master is extending the "IoDrvBase". This FB implements the interface "ICmpIoDrv" with a method called "IoDrvGetInfo". The method requires a "Pointer to Pointer to IoDrvInfo". The structure "IoDrvInfo" includes the var "szFirmwareVersion", which seems to be the same as in the information tab. </p> <p>If the driver is implementing the interface "ICmpIoDrv", this might be a quick and dirty solution to read the version. But I don't know if the information is valid. </p> <p>See the attached screenshots below, there is also a example code for the EtherCat_Master instance.</p> <p>Please let me know if there is a better way, which works for all devices </p> <p>BR,<br/> KevinR</p> <p><img alt="IMG: stIoDrvInfo.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2854"/></p> <p><img alt="IMG: devicedesc.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2853"/></p> <p><img alt="IMG: IoDrvInfo.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2851"/></p> <p><img alt="IMG: IoDrvBase.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2850"/></p> <p><img alt="IMG: EtherCatFB.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2849"/></p> <p><img alt="IMG: infotab.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2847"/></p></div>

<div class="markdown_content"><p>Thanks, it works for device (PLC).</p> <p>But how I can use it for POU from Device Tree? (for example, for Ethercat master device)<br/> Can you give me a little example?</p></div>
