Source ID
Specifies an identifier to indicate the source of the data. Each

Swap and Pad
When selected, high and low data bytes swap positions. Select swap
bytes when sending the message to a PLC/SLC. An odd number of
bytes is padded with a zero so that messages always contain an even
number of bytes. Note: Pass-Through data is not swapped.
