Select the “Change Parameter Source” link at the bottom of the “Edit Location Parameters” page.

The “Change Parameter Source” page appears.

The system displays the following field:

Location	The location for which parameter updation source must be modified.
	The description of the location is retrieved alongside.
	Zoom facility available.

The system displays the following fields in the “Parameter” multiline:

Parameter	The parameter for which source of updation must be defined.
Type	The type of the parameter, which can be “Attribute”, “Range” and “Consumption”.
Desc.	The description of the parameter.
Current Source	The current source from which the value of the parameter is updated.

Enter the following field in the “Parameter” multiline:

New Source	Use the drop-down list box to select the source from which the parameter value must be updated. The system provides the following options:
	Manual – Select this option, to indicate that the parameter value should be updated manually.
	RTI – Select this option, if the parameter must be updated from the real time integration system of the plant.
	Formula – Select this option, if the parameter must be updated by a formula. This option is applicable only for a range or a consumption parameter.
Formula	The formula to be specified for a parameter for which the “New Source” field is set to “Formula” (Alphanumeric, 150). Ensure that the formula is already defined in the “Create Formula” activity of the “Formula Builder” business component and is in “Active” status. Also ensure that the formula does not contain the parameter to which is it getting attached to (i.e.) the parameter displayed in the “Parameter” field.
	Press <Enter>. The system displays the “Formula Content” field in the multiline.
	Help facility available.

The system displays the following field in the multiline:

Changing the source of updation of parameter values – An overview

A parameter value of the location can be updated from various sources. They are:

Manual – The parameter value must be updated manually.
RTI – The parameter value must be updated from the real time integration system.
Formula – The parameter value must be updated by a formula.

You can specify the source of updation for the parameters of the location selected in the previous page. You can also enter a lLocation code directly in this page and update the source for its parameters.

If you are specifying the source as “Formula”, you must also specify the formula by which the parameter must be updated.
