8.1 Modbus Device List
The Modbus Device List page will show a listing of all the devices the EMB HubLite has configured. The
device list will show the Modbus address number, status (OK, Error, Alarm, Unconfigured), the device
name (user specified) and the device identification string. Device 250 represents the onboard pulse input
channels. Other devices must be added using Modbus TCP.
Click on the Modbus address number for any of the devices for specific device details.
NOTE: not all Modbus devices have built in driver support in the EMB HubLite . If a device appears in the
list with “Unknown” in the status column, you may need to upgrade the firmware on the EMB HubLite to
access the device. At the bottom of the device list page under the Type column, a link is shown that will
show all the Modbus devices with built in driver support provided in the firmware. Use the System/Firmware
update page to check for newer versions of the firmware. The www.leviton.com website FAQ also has a list
of supported Modbus devices. Modbus devices that are not supported by built in drivers may be configured
using the Modbus Framework feature in the EMB HubLite
At the bottom of the device list, there is an option to allow you to rename all the devices listed. This is useful
for initial deployments. There is also a troubleshooting link that will look for common configuration problems
and alert you to the appropriate solution.
