5.3 Application Details
1. Data Types: The data types supported by the AcuRev 1312 have
the following meanings.
Bit- binary value
Word- 16 bit unsigned integer using one register that contains 2 bytes. The data range is
0~65535.
Int16- 16 bit signed integer using one register that contains 2 bytes. The data range is
-32768~32767.
Dword- 32 bit unsigned integer using two registers that contains 4 bytes in total. The high bytes
follow the low bytes in this data type. The data range is 0-4294897295.
Int32- 32 bit signed integer using two registers that contains 4 bytes in total. The data range is
from -32768~32767.
Float-Single precision floating point number using two registers. The data range is
-2147483648~2147483647.
2.Relationship between communication value and real value.
The measurement values from the AcuRev 1312 meter obtained through Modbus may not al-
ways be equal to the real value. The values may be scaled or a relationship may need to be ap-
plied. It is very important that user is aware of these relationships when designing programs to
poll the meter, otherwise the values may not be accurate.
