meter’s serial port to use the EtherGate protocol, create the EtherGate site in ION
Setup or an energy management system, and add the serial devices to the EtherGate
site.
NOTE:
EtherGate supports only one master device.

Modbus Ethernet gateway
The meter’s Ethernet gateway feature extends the meter’s functionality by allowing
Ethernet access to serial devices connected to the meter’s RS-485 serial
communications port.
A
Gateway meter
B
Ethernet (multiple Modbus master TCP
connections)
C
Downstream serial Modbus slave
devices
D
Multiple Modbus master devices
A Modbus 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 meter receives Modbus TCP/IP data on TCP port 502,
translates it to Modbus RTU then forwards it to the addressed slave device.
This functionality allows the use of monitoring software to access information from
slave devices for data collection, trending, alarm/event management, analysis, and
other functions.
Configuring EtherGate using the display
Use the meter’s display to configure a serial port to use the EtherGate protocol.
1. Navigate to
Setup Menu > Communications Setup
and go to the serial
communications setup screen.
2. Set the serial port’s protocol to EtherGate. Configure the other serial port
parameters as required.
Configuring a Modbus gateway using ION Setup
You can configure Modbus gateway on your meter using ION Setup.
Before you begin, make sure you have completed the following tasks:
•
Confirm the serial network of devices are wired and configured to have the same
baud rate, serial port settings (for example, 8N1), and protocol (Modbus).
•
Confirm each serial device has a unique unit identifier.
•
Confirm the serial network of devices are connected to the gateway meter’s serial
communication port.
•
Confirm your gateway meter is communicating over Ethernet.
1. Start ION Setup.
