EthernetIPforCLXCom - WriteUDT
Used to write all data to a UDT in as few packets as possible using a Structure or Class that mimics the UDT. This is an extremely fast and efficient method to write a large amount of mixed data. NOTE : Requires Version 3.99x or higher
ControlLogix to .NET Data Type Equivalent

Code Samples
'* Writing all UDT data '* First a Class or Structure is needed to hold the data '* This Class/Structure must mimic the UDT
Public Structure MyUDT
DINTTag as Int32
LINTTag as Int64
End Structure
Dim MyStructureInstance as MyUDT
MyStructureInstance.DINTTag=1234
MyStructureInstance.LINTTag=5678
MyValue=EthernetIPForCLXCom1.WriteUDT("MyUDTTag",MyStructureInstance)
