User Data Types (UDTs) are used to generate structured data type blocks within the PLC programming environment for each DAP’s inputs and outputs. When you create tags to use in your program, you can then assign the appropriate data types for the given ConveyLinx module’s inputs and outputs.
Each given DAP consumes some number of input memory bytes and output memory bytes. When you use UDTs and create tags with the UDT data types; the PLC’s I/O memory is properly allocated and the memory boundaries between modules are easily established.
