Important Note Concerning the IQ 100 Series Modbus Map

In depicting Modbus Registers (Addresses), the IQ 100 Series meter’s Modbus map uses Holding

Registers only.

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 meter’s Modbus map also uses this representa-

tion.

Hex Description

0008 – 000F Meter Serial Number

Decimal Representation

The meter’s Modbus map denes 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 start-

ing at 40001. So instead of entering two separate values, one for register type and one for the actual

The meter’s Modbus map uses a shorthand version to depict the decimal elds -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 meter’s Modbus map

shows the following information for meter serial number:

Decimal Description

9 – 16 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 request-•

ing holding registers, take 40000 and add the value of the register (Address) in the decimal column of

the Modbus Map. Then enter the number (e.g., 4009) into the UI as the starting register.

For SCADA and Driver packages that use the 400001 to 465536 method for requesting holding reg-•

isters take 400000 and add the value of the register (Address) in the decimal column of the Modbus

Map. Then enter the number (e.g., 400009) into the UI as the starting register. The drivers for these

packages strip off the leading four and subtract 1 from the remaining value. This nal value is used

as the starting register or register to be included when building the actual modbus message.
