About Exporting PLC Data For Unity Pro

The Unity Pro Export command creates the Unity Pro I/O variable file (.xsy) in the Unity Pro XML format. You can create the file for the active project or active drawing. AutoCAD Electrical toolset suggests naming the XML data file based on whether you select to export for the project or a drawing. The default file name is either “Projectname.xsy” or “Drawing filename.xsy.”

The Unity Pro export file is generated from the PLC drawings and their respective PLC symbols. To ensure the proper importing and editing of the I/O variable file in Unity Pro, the variable name and variable type are maintained inside of the PLC drawings. Variable names and types are defined inside of Unity Pro and are the required for bidirectional updates.

Note: These values are maintained on the PLC module. If you delete the module from the drawing, the variable name and type are also removed.

Variable names and types are created for new I/O addresses for import back into Unity Pro. During the AutoCAD Electrical toolset import process, the rest of the addressing is filled in based on the available I/O points on the module. These additional I/O points receive a variable name and type upon import into AutoCAD Electrical toolset.

Variable Name	Takes on the address string as the value.
Variable Type	Takes on the same type as the other defined I/O addresses on the module. If I/O points are not defined on the module then Boolean characters are used.
