Examples

The following pages contain examples (referred to as samples) that illustrate the operation of the TC3 XML server. The examples are numbered consecutively and can be downloaded as a PLC project from here: TC3_XmlSrv_Samples.zip

• Getting started
  This section describes the general operation of the TwinCAT XML Data Server, the function of structures and arrays, and the access to individual nodes.
• Function blocks
  The application and configuration of the function blocks of the PLC library TcXmlDataSrv.Lib is explained based on four examples. (Examples 1-4)
• Further examples
  This document contains further examples, which describe the one-time initialization during PLC startup and cyclic writing, for instance. (Examples 5-6)
• Production example
  The production example illustrates the processing of a small production order. It uses FB_XmlSrvReadByName and FB_XmlSrvWriteByName. (Example 7)
