Sources and notes

  • Landis & Gyr E650 with RS485 DLMS-MODBUS Gateway (MarCom) · version 3.107 EN
    Modbus mapping area; up to four meters on one gateway, one map per meter

Source: MarCom, Landis & Gyr E650 with RS485 DLMS-Modbus Gateway, rev. 3.107 EN

  • The Modbus data comes from a DLMS to Modbus gateway made by MarCom that reads the E650 meters over RS485; the meter itself does not speak Modbus. Up to four meters connect to one gateway; this map is for meter 4 (meter 1 starts at 40016, meter 2 at 40216, meter 3 at 40416, meter 4 at 40616). The gateway-wide registers 40000 to 40014 are the same in all four maps.
  • The manual writes the addresses as 4x40000 to 4x40798 (holding registers); they are used here as they are with address_base 0. If reads come out one register off, the gateway counts from 1 and address_base should be 1.
  • Each value takes 2 registers (FLOAT, DINT or UDINT). The word order is not stated; big is assumed. A value the meter does not answer reads -1.
  • The meter's serial number must be written to the gateway (registers 40004, 40006, 40008, 40010 for meters 1 to 4, or on its web page) before the first reading. The gateway's default address is 192.168.0.122; Modbus RTU on its RS232 ports and Modbus TCP on its Ethernet port.
  • Energy and power registers carry the DLMS OBIS code in their description (for example 1.8.0 is total active energy A+, 1.6.1 maximum power in time slot 1). The 'previous month' values are the OBIS codes with an asterisk. Units are not given by the manual.
