Data Type Registers
Note:
All data records
have the same data types
assigned to them. The
user does not have to
read the data type
registers for every
record.
The 41xxx register series is used to identify the type of data items in the
30xxx series. The Data Type registers run in parallel with the Data
Registers. For example, Data Register 30041’s Data Type register is
41041.
Data Types are assigned 4 ASCII characters across 2 registers. If a Data
Type string contains less than 4 characters, then the rest of the string is
padded with NULL characters. Note that a Data Type using all four
characters will not end with a NULL character.
