a. 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 Anybus Communicator adopts this behavior
and strips off the corresponding four bytes from the consumed data.
