Changing the source from which the parameter must be updated

Select the “Change Parameter Source” link at the bottom of the “Equipment Parameter” page.

The “Change Parameter Source” page appears.

Enter the following field, if you wish to change the parameter source for parameters of an equipment other than the equipment selected in the precious page:

Equipment	The equipment for which the source of updation of parameters must be changed (Alphanumeric, 30).
	Press <Enter>. The system retrieves the “Type” field. The system also retrieves in the “Parameter” multiline, the parameters that are attached to the equipment. The description of the equipment is displayed alongside.
	Zoom facility available.

The system displays the following field:

Type

The type of the equipment, which can be “Normal”, “Rotable” or “Tool”.

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”.
Description	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.
	Parent – Select this option, to indicate that the parameter value should be updated from the parent equipment as defined in the “Equipment Creation” page. This option is applicable only for a consumption parameter.
	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.
	Parameter - The parameter (Consumption only) must be updated by a parameter (Attribute only).
Formula	The formula to be specified for a parameter whose “New Source” field is set to “Formula” (Alphanumeric, 150). The formula should be specified only for a parameter that is of type “Range” or “Consumption”. Ensure the following: the formula is already defined in the “Create Formula” activity of the “Formula Builder” business component or in the “Create Formula” page in this activity. the formula should be in “Active” status. the formula does not contain the same parameter to which it is attached.
	Press <Enter>. The system displays the “Formula Content” field in the multiline.
	Help facility available.

The system displays the following field in the multiline:

Formula Content

The content of the formula specified in the “Formula” field.

Check the box in the “Select” column of the multiline, to select the parameter for which you do not wish to define the source.
Click the Delete icon in the tool bar above the multiline, to delete the selected parameters from the multiline.
Click the “Edit” pushbutton, to update the parameter source.

The system displays the following fields in the “Record Statistics” group box:

Created By	The login ID of the user who created the equipment.
Created Date	The date and time on which the equipment was created.
Last Modified By	The login ID of the user who last modified the equipment.
Last Modified Date	The date and time on which the equipment was last modified.

Changing the source from which the parameter must be updated – An overview

A parameter value of the equipment 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.
Parent – The parameter value must be updated from the parameter value of its parent equipment.
Formula – The parameter value must be updated by a formula.
Parameter – The parameter (Consumption only) must be updated by a parameter (Attribute only).

This page allows you to specify the source from which parameter values can be updated. You can specify the source of updation for the parameters of the equipment selected in the previous page. You can also enter an equipment 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.

What you can do in this page

Change the source from which a parameter value can be updated

Specify a formula for a formula based parameter

Change the source from which a parameter value can be updated

Set the “New Source” field to “Manual”, to indicate that the parameter value must be updated manually.
Set the “New Source” field to “RTI”, to indicate that the parameter value must be updated through the real time integration system.
Set the “New Source” field to “Formula”, to indicate that the parameter value must be updated by a formula.
Set the “New Source” field to “Parent”, to indicate that the parameter value must be updated by the parameter value of its parent equipment.
Set the “New Source” field to “Parameter”, to indicate that the parameter (Consumption only) value must be updated by the parameter (Attribute only) value.

Specify a formula for a formula based parameter

Enter the formula that will be used to update a formula based parameter, in the “Formula – ID” field in the multiline.
