6.2.9 Integer16
A signed, 16-bit integer. Valid range is -2
15
(-32,768) to 2
15
-1 (32,767).
24-bit HMI: Signed data is represented in 2's complement form. The most significant 16
bits of the 24-bit host data contain the significant bits. The LS 8 bits are read as zero and
must be written as zero.
32-bit HMI: Same as 32-bit Integer type with useful values less than 2 16
(65,536).
SNMP: Bad Value may be reported if value magnitude exceeds 2 16
on a set operation.
6.2.10 Integer48
Integer48 is specific to 24-bit platforms. This type is a signed, 48-bit integer. On 32-bit
platforms
Integer48 is identical to the Integer type.
24-bit HMI: Data is stored in 2 consecutive memory locations. The most significant word
appears first. Signed data is represented in 2's complement form.
32-bit HMI: Signed data is represented as the single word in 2's complement form used
for the
Integer type.
SNMP: Only the least-significant 32-bits of the value is reported.
