Addr/Item = 1
•
Address 1 = ABCD (Item 1)
•
Address 2 = ABCD (Item 2)
Addr/Item = 2
•
Address 1 = AB (Item 1)
•
Address 2 = CD (Item 1)
Addr/Item = 4
•
Address 1 = A (Item 1)
•
Address 2 = B (Item 1)
•
Address 3 = C (Item 1)
•
Address 4 = D (Item 1)
8.2 Single-Precision Floating Point: Word Swap
[FORMAT ROSEMOUNT]
Formats numerical items as IEEE format single-precision 32-bit floating point numbers,
with a “word swap” byte order.
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 = CDAB (Item 1)
•
Address 2 = CDAB (Item 2)
Addr/Item = 2
•
Address 1 = CD (Item 1)
•
Address 2 = AB (Item 1)
Addr/Item = 4
•
Address 1 = C (Item 1)
•
Address 2 = D (Item 1)
•
Address 3 = A (Item 1)
•
Address 4 = B (Item 1)
8.3 Double-Precision Floating Point: MSB First
[FORMAT DOUBLE]
[FORMAT PHILLIPS DOUBLE]
Formats numerical items as IEEE format double-precision 64-bit floating point numbers,
with a standard ”MSB first” byte order.
