Slave Status Information
A 128 byte state field is transferred to the user program via the input data area
image. It contains information about the slave modules status and begins with
byte 8 of the input region. The status information encompasses 32 bytes of static
information and 96 bytes reserved for the extended status field. The content of
the extended status is controlled by the command "ExtStaSelect" byte in the
Device Command Register in the user program (byte offset 8-9).
