SCADA-Modbus® System Guidelines
100
Likewise, if polling the meter for engineering units, which are represented by integer
values, such as Flow Units of Measure or Level Units of Measure, the Modbus server or
MMI must be configured to read these values as Integers. If the server or MMI is
formatting this data as any data type other than Integer, the values will not be read or
displayed correctly.
Different Modbus servers and MMI manufacturers have different methods for configuring
the application to the appropriate data type contained within the register. Contact the
server or MMI manufacturer for details on how to configure the application to read the data
in the correct format.
