TwinCAT XML Data Server
The TwinCAT XML Data Server enables reading of data from an XML file directly into the PLC and writing of variable values from the PLC into an XML file. The structure of the variables in the XML document matches the structure of the variables in the PLC. Individual subelements of a variable can be accessed separately.
A PLC library contains:
- two function blocks for reading of variables from the XML file
- FB_XmlSrvRead
- FB_XmlSrvReadByName
- two function blocks for writing PLC variables to an XML file
- FB_XmlSrvWrite
- FB_XmlSrvWriteByName
Variables can be addressed via names or addresses.
