Script Transfer Object

Script Transfer Object

When you create a new script of the "Transfer object" type, three predefined methods are available:

Methods in the transfer object

Method	Description
Initialize	The method is called once when the OPC Router is started.
Write	The method is called after another transfer object has written data to this transfer object. It is therefore the code that is executed when this object is the target of a data transfer.
Read	The method is called before another transfer object reads data from this transfer object. It is therefore the code that is executed when this object serves as the source of a data transfer.

Use the "Settings - Manage parameters" menu to create the parameters and variables. You can define the following properties for the parameters:

Properties of parameters

When you create a new script, the script editor opens automatically.
