Chapter 4—Remote meter setup PowerLogic™ PM5500 series user manual

reconfigure ION Setup to match the new settings to re-establish communications with your meter.

1.If applicable, disconnect all serial devices presently connected to the Ethernet gateway’s RS-485 port.

2.Configure the Ethernet gateway’s serial port settings to match the meter’s default serial communications settings:

—Baud rate = 19200

—Parity = Even

3.Connect the meter’s RS-485 port to the Ethernet gateway.

4.Connect the Ethernet gateway to the LAN.

5.Start ION Setup in Network mode.

6.Add an Ethernet gateway site and set its properties:

—IP address = IP address of the Ethernet gateway

—Port = 502 (for Modbus RTU)

7.Add a meter to the site and set its properties:

—Type = PowerLogic PM5000 series Power Meter

—Unit ID = 1

8.Use the RS-485 Base Comm setup screen to modify the meter’s serial communications settings.

RS-485 port settings

Parameter	Values	Description
		Select the communications format used to transmit
	Modbus RTU, JBus,	data. The protocol must be the same for all devices in a
Protocol		communications loop.
	ASCII 8, ASCII 7	ION Setup does not support ASCII 8, ASCII 7 or JBus
		protocols.
		Set the address for this device. The address must be
		unique for each device in a communications loop. For
		JBus protocol, set the device ID to 255.
Address	1 to 247	This value is used in both Ethernet and serial
		communications; if you change this value, you need to
		update your meter properties in ION Setup to re-
		establish Ethernet communications.
		Select the speed for data transmission. The baud rate
Baud Rate	9600, 19200, 38400	must be the same for all devices in a communications
		loop.
		Select None if the parity bit is not used. The parity
Parity	Even, Odd, None	setting must be the same for all devices in a
		communications loop.

9.Click Send to save your changes to the meter. You need to reconfigure ION Setup to match the changed settings in order to re-establish communications with your meter.

NOTE: If you set the protocol to ASCII 7, ASCII 8 or JBus, you cannot use ION Setup to reconnect to the meter — ION Setup does not communicate using these protocols.

10. Exit ION Setup.

Meter setup through RS-485

After the meter’s RS-485 port is configured and connected to the RS-485 network, you can use ION Setup to configure all other meter setup parameters.
