System Subsystem Records

System Subsystem records store information about a system of equipment or locations. The following table provides an alphabetical list and description of the fields that exist for the System Subsystem family. 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
Connections	Text	This field is used internally by the GE Digital APM system to store connections in the diagram.	This field does not appear in the Properties pane.
Description	Text	Any additional information regarding the subsystem.	On the System Subsystem datasheet, you can define this value manually by entering text in the Description box. This field appears in the General section.
Diagram	Binary	This field is used internally by the GE Digital APM system to store the diagram.	This field does not appear in the Properties pane.
Element Properties	Text	This field is used internally by the GE Digital APM system to store element properties.	This field does not appear in the Properties pane.
Fixed Cost	Number	The cost of lost production when the subsystem fails. Fixed cost does not change as a result of other variables such as downtime.	By default, this value is set to 0 (zero). This field appears in the Financial Consequences 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.
Lost Production Cost	Number	The cost of lost production per unit of time when the subsystem is not running.	By default, the Lost Production Cost is set to 0 (zero). This field appears in the Financial Consequences section.
Lost Production Cost Units	Character	The time units for the Lost Production Cost field.	You can select a value from the following options: Per Hour Per Day Per Week Per Month Per Year This field appears in the Financial Consequences section.
Name	Character	The name of the Subsystem.	This value is populated automatically with Subsystem. 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 and each one contributes 50% to the overall production output, you would enter a value of 50 in the Production Contribution field for 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 or location does not contribute to the overall production output of its parent system, you can set the Production Contribution to 0 (zero). The value in the Production Contribution field of the Default subsystem or Root Subsystem is disabled on that subsystem's Properties pane. This field appears in the General section.
Variable Cost	Number	The cost incurred during the downtime due to subsystem failures or shutdowns.	By default, the Variable Cost is set to 0 (zero). This field appears in the Financial Consequences section.
Variable Cost Units	Character	The time units associated with the value in the Variable Cost field.	You can select a value from the following options: Per Hour Per Day Per Week Per Month Per Year This field appears in the Financial Consequences section.
