1. you need to add/check if a component is in your runtime:<br/>
Component.x=SysEthernet<br/>
(runtime config)</p>
<ol>
<li>use the following snippet:</li>
</ol>
<p>declare:<br/>
diNumber: DINT;<br/>
iAdapter: DINT;<br/>
stName: STRING(255);<br/>
stDescription: STRING(255);<br/>
aby_address:ARRAY<span>[1..6]</span>OF BYTE;</p>
<p>program:<br/>
getnumberofadapters(ADR(diNumber));<br/>
FOR iAdapter := 0 TO diNumber DO<br/>
getadapterinfo(<br/>
iAdapterNum := iAdapter, <br/>
pbName := ADR(stName), <br/>
pbDescrition := ADR(stDescription), <br/>
iBuffersize := SIZEOF(stName), <br/>
iMacLength := 6, <br/>
sMacAdress := ADR(aby_address));<br/>
END_FOR</p>

Now i get it by outer ARP request and send the result back to IEC-task. But it's inconvenient way, and it doesn't work behind router (router changes PLCs MAC on its own). i need something local and universal to get MAC in IEC-code.</p></div>How to get MAC-address?2020-02-27T14:23:15.462000Z2020-02-27T14:23:15.462000ZRolf-Geislerhttps://forge.codesys.com/u/rolf-geisler/https://forge.codesys.com7a4d09d8c356022a77151a585452c05717703e38<div class="markdown_content"><p>Windows-system?<br/>
If yes<br/>
==> start menu "Run"<br/>
Enter "cmd" + Return<br/>
"ipconfig" will return the IP and MAC addresses of all present network adapters.</p></div>How to get MAC-address?2020-02-27T14:23:15.057000Z2020-02-27T14:23:15.057000ZMousehttps://forge.codesys.com/u/mouse/https://forge.codesys.com27d241a0e903dfa3cf8f708e9a2b49cc7fc889cc<div class="markdown_content"><p>Hello!<br/>
There is the function "getadapterinfo" in CmpSysEthernet.library. I try to use it to get MAC of local Ethernet adapter. But i can't understand what it gets me. The field MAC, which the function returns, doesn't match the real MAC of any adapter in my PC. Unfortunately I can't find extra information of this function. </p>
<p>Is some other function (way) there, which can get MAC address?</p></div>
