B.6: Important Note Concerning the Shark ® 200 Meter's Modbus
Map
In depicting Modbus Registers (Addresses), the Shark® 200 meter's Modbus map
uses Holding Registers only.

B.6.1: Hex Representation

The representation shown in the table below is used by developers of Modbus drivers
and libraries, SEL 2020/2030 programmers and Firmware Developers. The Shark ®
meter's Modbus map also uses this representation.
B.6.2: Decimal Representation
The Shark ® meter's Modbus map defines Holding Registers as (4X) registers. Many
popular SCADA and HMI packages and their Modbus drivers have user interfaces that
require users to enter these Registers starting at 40001. So instead of entering two
separate values, one for register type and one for the actual register, they have been
combined into one number.
The Shark ® 200 meter's Modbus map uses a shorthand version to depict the decimal
fields, i.e., not all of the digits required for entry into the SCADA package UI are
shown. For example:
You need to display the meter's serial number in your SCADA application. The Shark
® 200 meter's Modbus map shows the following information for meter serial number:
In order to retrieve the meter's serial number, enter 40009 into the SCADA UI as the
starting register, and 8 as the number of registers.
• In order to work with SCADA and Driver packages that use the 40001 to 49999
method for requesting holding registers, take 40000 and add the value of the regis-
