Definition and Alarms Tabs
When you have selected a row in the Modbus Address table, you can alter the settings in the Definition tab
(below the table) and you can set alarms to monitor any measurement by selecting the Alarms Tab.
Data Name, Description, Engineering Units, Address and Data Type
Choose a suitable data name for the location and add a description to help you interpret the reading. Select
suitable engineering units from the drop down box after the Data Name.
Take the Address and Data type from the Modbus Map for the device. Do not enter the address as an offset,
enter the full address (e.g. 30830 not 830).
Note: The data name becomes the Field Name in the database table for the device.
Scaling
To scale the raw data from the Modbus register enter a range for the raw data (Max Raw and Min Raw
fields) and the corresponding range for the engineering data (Max EU and Min EU fields). Add an offset in
engineering units to offset the engineering units.
In the example shown above, the raw data of 0 to 1000 represents 0 to 100.0 m/s.
Alarm Settings
You can set alarms in the Alarms Tab. These will trigger SMS or Emails according to the select for the rele-
vant custom devices group. No alarms will be sent unless the checkbox for Enable Alarms is ticked.
In the example shown, an alarm is set for wind speeds above 20m/s which last for more than two minutes.
