CHAPTER 9 — COMMUNICATION
9.1 Communication Connections
The ElNet Energy & Powermeter supports RS485 and
Ethernet. The connection is provided on the Rear Panel, (see
Figure 2.5 or 2.6) and is made by means of the connectors
provided. The same information can be transmitted along both,
but only one at a time. The user can choose the one that best suits
his current situation and equipment.
The RJ45 sockets support a standard connection to any Ethernet
network.
9.2 Communication Settings
To enable the User connecting the ElNet Energy &
Powermeter to a PC master computer for successful
communications, the Communication Setup parameters of both
must match; i.e. the port of the PC master and the configuration
settings of the Powermeter.
9.3 Address
Each Powermeter in a communication system must have its own
unique address.
Since the ElNet Energy & Powermeter works on MODBUS,
the available addresses are from ‘1’ to ‘247’. BACnet
communication is also available.
