ZSelect GE LM10 under GE Multilin.

If the slave is not displayed in the slave catalog, it can be added using the EDS file:

ZClick the Have Disk tab in the slave catalog, then open the EDS file for the LM10.

We can also add the slave device to the master card from Tool Chest:

ZClick the Tool Chest icon in the tool bar.

ZOpen the drawer of DeviceNet™ devices, select the LM10 slave device under the GE Multilin folder, and drag it onto the DeviceNet™ master card.

ZSet the MAC ID on LM10 module equal to the one displayed under the General tab of the Slave Properties window.

ZTo see the slave properties window, right click on the Slave Device, add it to the Master, and select Network Setting.

ZRight-click on Slot 2 where the master card is added.

ZSelect Network Setting to view the DN9030 master properties.

ZRight-click on the LM10 slave device added under the master card for Setting Slave Properties.

ZSet the baud rate in DN9030 master properties window equal to baud rate of the LM10 slave device.

The LM10 has three (3) baud rate settings: 125, 250, and 500 kbps (125 kbps is the default value).

ZConnect the LM10 as per Wiring Diagram on page 2–15.

As well, energize terminal pin 21 with 120 V to enable network control.

To determine the correct slave input register (%I00xx) and slave output register (%Q00xx), double-click the added slaves under the master and note register 3 for connections 1 and 2.

A.2.5 Polling Input/Output Connection

Input/output messaging is for time-critical, control-oriented data. It provides a dedicated, special purpose communication path between a producing application and consuming application.

The Polling Input/Output Connection will accept 1 byte of command data and returns 1 byte of device status data and 6 bytes of current metering data for poll data group 1 (2 bytes each for phase A, B, and C currents).

ZSet the network to polling mode on the master side.

ZUnder the General tab, set the baud rate equal to the baud rate of the slave device.

ZAlso, set the Scan Interval and Reconnect Time.

ZSelect the Polled option under the Connection 1 tab.
