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.
-
Confirm that the Modbus RTU and Modbus TCP/IP Ethernet protocols are enabled on your gateway meter.
- Start ION Setup.
- Open the Setup Assistant for your meter.
- Navigate to and select the tab for the communications port that the serial network is connected to.
- Select Protocol and click Edit.The protocol selection screen appears.
- Set the protocol to Modbus Master.
- Navigate to Communications > Basic Ethernet and select the TCP/IP tab.
- Select Modbus Gateway and click Edit.The Modbus gateway selection screen is displayed.
- Select the communications port that the serial network is connected to (and you just set to use the Modbus master protocol) and click OK. The Modbus gateway connection is created.
- Create an Ethernet gateway site to access the serial network of devices through your gateway meter.
