15.2.Meters
Insite pro M allows to connect up to 16 meters with RS-485 interface. Supported are ABB M2M, M4M and
EQ meters with Modbus RTU communication protocol. Each meter can be assigned to Modbus ID from 1
to 16.
Data from meters are available on the control unit WebUI and using Modbus TCP or Modbus RTU protocol.
When accessing through Modbus protocol, registers of each connected meter are mapped to control unit
static register map. The map is attached in the Excel file in the tab cu insite:

Control unit register map provides information about address for each quantity, number of registers
on which it is presented and data type. The details for each register depend from meter type which is
connected to specific slave Modbus ID and are available in the Excel file in the tab meters.
E.g. EQ meter is connected to Modbus ID 1. The Active import L1 variable is available on the control unit
register address 37638. It can be read from the meters tab in Excel file that the unit for this register is
kWh, register is not writable, quantity is refreshed every 30 seconds for Modbus and WebUI and stored
every 900 seconds on the internal flash memory. The multiplier for this register is 0.01. To retrieve this
quantity the EQ meter Modbus register 5460 is queried.

If the register address for quantity is 0, then it means that meter is not queried for this value and it is
calculated by control unit, using other available data.
