DATABASE DESCRIPTION
2-7
Data Type Bytes Range Remarks
Floating
Point * (F) 4 ±1.18*E-35 to
±3.4*E38
The floating-point data type is a four-byte data value in IEEE
standard floating point format.
Logical
Source
Pointers * 4

(ICN)
A logical source pointer uniquely identifies an attribute in the
database. It is a four-byte value, with bit fields for the function
block type, block occurrence number, and attribute number for
the specific attribute. LSP's are used mainly in building lists and
in messages.
For ICN messages, LSP's are two byte values, with the
organization of the block type, occurrence and attribute fields
dependent on the block type. This format allows consistency
with the existing MOD 30 ICN architecture.
ASCII * (A) n “any text”
(for up to 126
bytes)
A data item of type ascii consists of one byte, which contains the
length of the ascii string, followed by the number of bytes
specified in this first byte. Each byte contains an ascii character.
For example, a field size may be configured to be 12 bytes but
the data may only have 6 ascii characters plus a byte count for a
total 7 bytes of data.
Continuous 2 –204.8% to
204.8%
A decimal point is always required to distinguish continuous data
from counts, even when nothing follows the decimal point. For
instance, 100. is recognized as a continuous value while 100 is
recognized as a count.
The continuous data type is a two byte signed (two's
compliment) value. Values of 0 to 16000 represent continuous
values from 0. Thus, the continuous data type has a range of -
204.8% to 204.8%. This data type is available for the purpose
of compatibility with MOD 30 instruments.
Hex * (H) n $00 to $FF
(for up to 126
bytes)
A data item of type hex consists of one byte, which contains the
length of the hex string, followed by the number of bytes
specified in this first byte (similar to ascii). Hexadecimal
numbers must be preceded by $ e.g. $00, $0AF7 etc.
MOD 30
Controller
Modes 1 Special Bit Array The MOD 30 Controller Mode data type is a special bit array
data type. It is available as a data type only for the purpose of
compatibility with the MOD 30 XL Controller.
Address 0:
0 = Autotune Mode
1 = Feed Forward
2 = FF Feedback
3 = Cascade
4 = Auto State
5 = Manual
6 = Direct Digital Control
7 = Output Track
