<StructType name="isos">
<Component identifier="my_name" type="std:STRING">
<VisibleName name="local:my_name">MYNAME</VisibleName>
</Component>
<Component identifier="my_value" type="std:DWORD">
<VisibleName name="local:my_value">MYValue</VisibleName>
</Component>
</StructType>

I defined a structure type as Input in my device description file. I install clearly my device desciption file to codesys editor. And , I wrote a I/O Template library in C programming as given codesys examples. Everything are OK until I try to login . Return an error from codesys editor . It says address aldready used. When I change String type to dword type in my device description , everything are working well. What is the wrong with a string type in device description ? How will i define string in c programming side ? I read documentation , it says default max 80 char for string . Any help , Any example please .

How can I use std:string with Structure Type in device description. How can I match them in Codesys C programming I/O template library ? Please help .
