Eight (8) bytes are used to represent the item, with the bytes being distributed across
register addresses according to the Addr/Item selection (A = MSB, etc.):
Addr/Item = 1
•
Address 1 = ABCDEFGH (Item 1)
•
Address 2 = ABCDEFGH (Item 2)
Addr/Item = 2
•
Address 1 = ABCD (Item 1)
•
Address 2 = EFGH (Item 1)
Addr/Item = 4
•
Address 1 = AB (Item 1)
•
Address 2 = CD (Item 1)
•
Address 3 = EF (Item 1)
•
Address 4 = GH (Item 1)
8.4 16-bit Integer
[FORMAT ENRON-16-BIT]
Formats numerical items as 16-bit SIGNED integers, ranging from –32767 (hex 8001) to
32767 (hex 7FFF).
Two (2) bytes are used to represent the item, with Addr/Item = 1 the only permissible
option (A = MSB, etc.):
Addr/Item = 1
•
Address 1 = AB (Item 1)
•
Address 2 = AB (Item 2)
8.5 32-bit Integer
[FORMAT ENRON 32-BIT]
Formats numerical items as 32-bit SIGNED integers, ranging from -2,147,483,647 (hex
80000001) to 2,147,483,647 (hex 7FFFFFFF).
Four (4) bytes are used to represent the item, with the bytes being distributed across
register addresses according to the Addr/Item selection (A = MSB, etc.):
Addr/Item = 1
•
Address 1 = ABCD (Item 1)
•
Address 2 = ABCD (Item 2)
Addr/Item = 2
•
Address 1 = AB (Item 1)
