3.28 String Box settings Screen
The Module string box setting screen has a similar layout to the Custom devices screens. The difference is
that you can only add preconfigured string box types and there is no alarm setting at register level. Alarms
are set for all string boxes in the alarm screen shown below.
The settings screen still allows you to change ‘Name’, ‘Description’, ‘Comm. Device’ and Modbus station val-
ues as well as enabling the module and alarm monitoring for the module in the same way as custom de-
vices.
Note: The ‘Name’ field is used for the database table name for that device in the historical database.
Voltage module and Voltage factor
These values are used to compensate for differing cable losses around the plant.
Active digital output when alarm [XI+]
Each Transclinic XI+ has a digital output. If you check this box and there is an alarm condition for any of the
strings monitored by this Transclinic it will operate the digital output. The output can be attached to a relay
that operates a light on top of the combiner box to make it easy to find faults. You can use it however you
want.
Enable lines
You can enable or disable each measurement by clicking on the beginning of the line. A green tick will ap-
pear if the value is being monitored.
