Ethernet gateway
Ethernet gateway is a communications method that allows you to communicate
through a gateway device to a serial network.
When a meter with gateway capabilities is installed on an Ethernet network, a
master device (such as an energy management system) can communicate
through the gateway meter to a serial network of devices connected to the
gateway meter’s serial port(s). The maximum number of devices on the serial
network is determined by the limitations of the gateway meter’s serial port.

There are two types of Ethernet gateways that you can configure on your meter:
•
EtherGate: a single TCP connection communicates through the gateway
meter to a serial network of devices.
•
Modbus gateway: up to a maximum of 32 Modbus master TCP connections
communicate through the gateway meter to a serial network of Modbus
devices.
EtherGate
The meter can function as an Ethernet gateway (EtherGate).
EtherGate is a protocol-agnostic communications method that lets you
communicate through a gateway meter to a serial network of devices letting ION
or other RTU over TCP data pass through the gateway meter to other networks,
including third party systems. When a meter installed on the Ethernet network has
EtherGate enabled, a master device (such as an energy management system)
can communicate through the gateway meter to a serial network of devices wired
to the gateway meter’s COM port. You must create an additional communications
connection to the gateway meter in order to read its information.
NOTE:
EtherGate supports only one master device.
