System Buffer Records

System Buffer records store information about buffers that exist in the System Analysis diagram. The following table provides an alphabetical list and description of the fields that exist for the System Buffer family and appear by default on the System Buffer datasheet. The information in the table reflects the baseline state and behavior of these fields. This list is not comprehensive.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.

Field Caption	Data Type	Description	Behavior and Usage
Description	Text	Any additional information regarding the buffer.	On the System Buffer datasheet, you can define this value manually by entering text in the Description box. This field appears in the General section.
GUID	Character	A value that uniquely identifies the record within a System Reliability Analysis.	This value is generated automatically by the GE Digital APM system and disabled. In System Reliability Analyses, GUIDs are used to identify records because Entity Keys will not exist until a record is saved. Because a System Reliability Analysis may contain unsaved records, it is necessary to use a value that uniquely identifies those records within the system. This field does not appear in the Properties pane.
Initial Quantity in Percentage	Number	The percentage of product that the storage tank contains at the time of a failure.	By default, the value is set to 100. This field appears in the Buffer section.
Name	Character	The name of the buffer.	This value is populated automatically with Buffer. You can define this value manually. This field appears in the General section.
Production Contribution	Number	The percentage that this piece of equipment or location will contribute to the overall production capacity of its parent system, with respect to other elements that are running in parallel to the piece of equipment or location. For example, if two pieces of equipment are running in parallel with one another and each one contributes 50% to the overall production output, you would enter a value of 50 in the Production Contribution field of each piece of equipment. The Production Contribution of each element in the Diagram will be used to calculate the overall production loss of the parent system when one or more elements are down.	By default, the Production Contribution is set to 100. If the piece of equipment does not contribute to the overall production output of its parent system, you can set the Production Contribution to 0 (zero). This field appears in the General section.
Time to Empty	Number	The time that it will take for the contents of a full buffer to empty when it is used.	By default, the Time to Empty is set to 0 (zero). This field appears in the Buffer section.
Time to Empty Units	Character	The time units that apply to the value in the Time to Empty field.	You can select a value from the following options: Hours Days Weeks Months Years This field appears in the Buffer section.
Time to Refill	Number	The time that it will take for the contents of an empty buffer to refill completely after it has been emptied.	By default, the Time to Refill is set to 0 (zero). This field appears in the Buffer section.
Time to Refill Units	Character	The time units that apply to the value in the Time to Refill field.	You can select a value from the following options: Hours Days Weeks Months Years This field appears in the Buffer section.
