Verifying ION power meter communication

Communication from the ION power meter to the Observer software includes:

Serial Modbus communication from the power meter to the Modbus base station device

Ethernet Modbus/TCP communication from the Modbus base station device to the Observer software

To make sure that the ION power meters communicate correctly with the server and Observer software, verify the following connections.

Verify the ION power meters (in a daisy chain configuration) are connected to the Modbus base station via an RS-485 serial connection.

o If multiple ION power meters are connected to the Modbus base station (in a daisy chain), verify that each power meter has a unique device ID ("Programming the Modbus ID" on page 59) and that the last meter in the configuration has the terminating resistor connected ("Programming Modbus communication" on page 59).

o If multiple ION power meters are connected to the Modbus base station (in a daisy chain) and some of the power meters are not communicating, verify that the RS-485 connections down the daisy chain are securely connected.

o Verify that all cable connection points are installed and securely fastened to the terminal block.

Verify the Modbus base station is connected to the server network connection via Ethernet cable. o Verify the Modbus base station is powered on.

o From the server, ping the Modbus base station to verify it is connected to the network.

o Verify the Modbus base station has the duplex setting set to Auto Duplex ("Verifying network settings" on page 73).

Verify that the Modbus plug in component was installed during the Device Manager installation. If the Modbus plug in component was not installed, the Observer software cannot communicate to the ION power meters, and no Modbus communication occurs to the Edge server.
