<p>The library "SysCom" internally uses another library, "SysTypes2Interfaces", where some datatypes are defined. </p>
<p>The function "SysComOpen" in "SysCom" is of type "RTS_IEC_HANDLE", which is defined in SysTypes2Interfaces. That's the reason, why the error occurs.<br/>
So you will have to export the Codesys Library "SysTypes2Interfaces" into TwinCat, too, or you have to build your own library with that name and define the needed datatypes there.</p>
<p>Good luck!</p>
