8. You can add another case/rule to the current translation by adding a new one or copying an
existing one. The copying method is recommended for creating more complex rule-based
translations. The method you choose depends on whether you want to re-use the previous
case/rule.
•
To create a new case/rule in the current translation by re-using a previous one, right-click the
top-level
IF-THEN statement, click Copy on the shortcut menu, right-click the top-level
IF-THEN statement again, and then click Paste on the shortcut menu. You can use this

Example Type Translator for Street Lighting Network
You can use a type translator to control a street lighting network. In the following example, the state
and value of a switch is translated to the luminaires on a network when a
SNVT_switch data point on
the SmartServer is enabled. This application can be useful in case of an emergency on the road where
one or more luminaires need to be turned on remotely when they are normally scheduled to be off.
In this example, a dynamic SNVT_switch data point on the type translator functional block and the
SNVT_switch data point of switch device are specified as the input points, and the SNVT_switch data
points of four luminaires are specified as the output points.
A custom rule-based translation is used to translate the state and value of the switch to the luminaires.
If the type translator is enabled (the state of its “Enable” data point == 1), then the state and value of
the switch are copied to each of the luminaires.
