4 Devices
4.1 Energy Meter D370
4.1.1 Connection to computer
Example 1:
The Energy Meter D370 has an RS485 interface and the PC has an RS232 interface. An interface converter
is required.
Example 2:
The Energy Meter D370 has an RS485 interface and the PC has an Ethernet interface. A gateway is re-
quired. The following devices can be used as gateways: Energy Analyser D550, Energy Analyser 550.
4.1.2 Adding device
Integrating Energy Meter D370 in ecoExplorer go
• The Energy Meter D370 must be connected to the PC via a gateway (device type) or via an interface
converter (Example of connection).
CreateanewEnergyMeterD370inecoExplorergoanddenetheconnectiontype(Firststeps,Adding
new device).
Connection types
Ethernet gateway (e.g. for the devices connected to the RS485)
A gateway is required to be able to connect the Energy Meter D370 via Ethernet to the PC and to be able to
congureitandreaditwithecoExplorergo.
• The Energy Meter D370 has an RS485 interface.
• The gateway must have both an RS485 and an Ethernet interface (e.g. a Energy Analyser D550 with the
appropriate options).
• Thegatewayaddress(e.g.192.168.1.1)mustbesetundertheconnectionsettings(seeFig.Conguring
the connection).
• Because more than one Energy Meter D370 can be connected to the gateway, the device address set in
theEnergyMeterD370mustalsobesetundertheconnectionsettings(seeFig.Conguringtheconnec-
tion).
• If no connection could be established to the Energy Meter D370, an attempt will be repeated following
the set Timeout.
• When attempting to read data from the Energy Meter D370, the number of attempted connections will be
limited by the number set under max. no. of attempts.
• The connection protocol must be set via the Modbus protocol. TCP/IP packets are used when connecting
via Modbus TCP. The TCP port 502 is reserved for Modbus TCP.
• When measuring online, the ecoExplorer go will repeatedly attempt to establish a connection to the En-
ergy Meter D370.
