8.9 Alarm Setup
The Modbus Alarms section provides the ability to send messages when alarm levels are exceeded.
Messages can be sent by email, SNMP or displayed on the LCD console. Alarms are processed at the end
of the data logging period. For more frequent alarms, shorten the data log interval. Log readings and alarm
processing can be set to as often as once per minute.
Display all alarms on LCD console: When checked, all alarm messages are shown on the LCD display of
the EMB HubLite.
SNMP Trap Send Enabled: When checked, SNMP Trap messages are sent after every log period for each
data point that is in an alarm state. The trap includes information about the EMB HubLite system data point,
and alarm state. A full MIB is located on the EMB HubLite , click the MIB link to the right of this option.
SNMP Trap Host 1 (2,3): When SNMP traps are enabled, a trap message is sent to each of the trap
host addresses. Specify the trap host by IP address, not DNS name.
Direct email on alarm. When checked, the EMB HubLite will send an email message when any data point
changes its alarm state.
SMTP Mail HUBLite Address: The IP address of the email HubLite on the LAN that will process and
forward the email message to the recipient.
Sender Address: The address that will be used in the “From:” line of the email. This is helpful in identifying
the source of the alarm email message. If your SMTP mail HubLite has junk filtering, you may be required
to use a sender address that matches a mailbox address on the SMTP mail HubLite; check with your mail
HubLite administrator for specific details on this issue.
Recipient address 1 (2,3): The EMB HubLite can send a copy of the alarm notice to multiple
email addresses. Specify one, two or three email addresses in the fields provided for the
recipient addresses.
8.10 Modbus Framework
The Modbus Framework feature is a tool to allow the EMB HubLite to read data from any Modbus device
by creating a template in the Modbus Framework editor. The template describes the Modbus register read
commands, and the conversion required for each data point that is to be read. The Framework feature is
an advanced feature of the EMB HubLite that requires the user to be familiar with the Modbus protocol and
with the Modbus register point list for the specific Modbus device that will be used. For more information on
the Modbus Framework feature, download the Modbus Framework documentation from www.leviton.com
