Data_Type*
‘Flag’ - each byte of Indication statuses will be
stored in 8 consecutive locations in the Data
Array. On write; one Control byte will be
composed from 8 consecutive locations.
‘Byte’- each byte of Indication statuses will be
stored as an 8 Bit Integer at the specified
location. On Write; one Control byte will be
composed from a single location.
‘Register’ - two bytes of Indication statuses will
be stored as a 16 Bit integer at the specified
location. On Write; two Control bytes will be
composed from a single location.
’32-Bit_Reg’ four bytes of Indication statuses
will be stored as 32 Bit integers at the
specified location. On Write, four Control bytes
will be composed from a single location.
