Assignment of Input Parameters Tab

Use

You use the Assignment of Input Parameters tab to define the information that is to be passed on to a destination system using the notification.

The output values of the notification are based on different data sources, depending on the notification type:

For method notifications for methods with direct destination system call, the input parameters of the method are used for generating the output expressions.
For method notifications for an EMP method with destination system call, the output expressions are derived from the input variables that the EMP implementation provides for the destination system call.

Note

For EMP methods, the input parameters of the method are adopted directly from the EMP implementation; PCo does not provide for any configuration option here.

You have configured an OPC UA server or a Web server on the agent instance and loaded a method definition from an EMP assembly into the PCo configuration.
You have created a method notification.

Select the method notification and click on the Assignment of Input Parameters tab.

The table with the output expressions is still empty.
In the simplest scenario, where there is a 1:1 relationship between an EMP input variable and the expression being output, choose the Generate Expressions icon. This function generates all expressions for the EMP input variables automatically. These expressions are then displayed in the Output Expressions table.

Note

By clicking on the header row of the table of output expressions, you can sort the table by the content of the selected column.

For more information about the icons, see Output Tab.
