Note
Rockwell Automation PLCs have the first four bytes consumed by a device defined as
status information. This behavior is specific to devices from Rockwell Automation and is
not defined in the EtherNet/IP specification. However, since all known PLCs are
implemented this way, the Micro Motion EtherNet/IP Module adopts this behavior and
strips off the corresponding four bytes from the consumed data.
