System Variables

System variables are used to set parameters within IFS/Asset Design. These variables are similar to the user properties in IFS Applications.

A defined system variable has a name (variable type), value (e.g., the name of the field label on a window), and a description (a short text explanation of the variable and its usage). Standard and plant are also required for each system variable.

IEC Object Structure Prefixes

The five IEC object structures have default prefixes. There are five system variables that can be used to redefine the object structure's prefix. The default delimiter that separates the structure values and their prefixes can be redefined as well.

System Variable	Default Prefix
Functional Structure Prefix	=
Locational Structure Prefix	+
Product Structure Prefix	-
Control System Structure Prefix	== or #
Topographical Structure Prefix	++
Structure Description Delimiter	.

However, these system variables will not be used anymore.

Switchgears

There are six variables used to total motor loads that are preliminarily booked to switchgears. They are:

Consumer w_load attribute
Consumer va_load attribute
Consumer avg_load attribute
Switchgear preliminary w_load attribute
Switchgear preliminary va_load attribute
Switchgear preliminary avg_load attribute

The correct summation of these values is dependent on compatible units of measures (e.g., W and kW), as defined in IFS/Application Services. However, these system variables will not be used anymore.

MC Check Records

The check record system variables are used to set up fields on certain object detail windows. These fields are used to enter the name of the equipment data sheet for which information is sent back and forth. If you are setting up MC check records for an object, the first check record system variable is required; the second is optional. The check record system variables are:

Check Record1 attribute
Check Record2 attribute

Refer to the MC check record template for permissible variable values.

Design Codes Collection

The default value for the code collection when allocating design parts to objects is set by the Code Collection system variable. The value % enables the collection for all users.

Status Change and Data Exchange between IFS/Asset Design and IFS/Equipment

Changing an object's design status will, in most cases, involve the transfer of data from the design object in IFS/Asset Design to the equipment object in IFS/Equipment. Data can also be transferred in the opposite direction (from the equipment object to the design object) during an object redesign.

System variables are configured to handle data transfer between objects undergoing a status change. There are six types of system variables. Each of these types is available in two transfer formats: Design to Equipment and Equipment to Design.

A default value is applied in the event the system variable is not defined. The values entered for these system variables are the actual numbers (1, 2, TRUE, FALSE, etc.). An error message results if, for example, the value 3 is defined for the Spare Parts from Equipment to Design variable.

Match Object Level And Type

Object Level and Object Type will be primarily checked when:

An existing equipment object is being created in Asset Design.
A design object is being transferred, as a result of a status change, to Equipment or vice versa.

By default, the information on an object from Equipment or Asset Design is transferred to its asset design or equipment counterpart respectively, regardless of differing object types and object levels.

System Variable	Value/Description
Design to Equipment -Match Object Level and Type Equipment to Design - Match Object Level and Type	TRUE = Consider Object Type and Level when transferring data. FALSE = Ignore Object Type and Level when transferring data (default)

Technical Attributes

Technical attributes are the alphanumerical and numerical values entered in fields within the registration windows. The default value when changing design/operational status is to replace all values except those that are null (have no value).

System Variable	Value/Description
Technical Attributes from Equipment to Design Technical Attributes from Design to Equipment	1 = Replace all values 2 = Replace all values but not if a new value is null (default) 3 = Insert value only if value is missing

Spare Parts

Additional parts are sent from IFS/Asset Design to IFS/Equipment to become spare parts. Spare parts created within Equipment also can be transferred to Asset Design. The default value will adjust the spare part quantities and add new spare parts.

System Variable	Value/Description
Spare Parts from Equipment to Design Spare Parts from Design to Equipment	1 = Replace the spare parts list 2 = Update the existing spare part fields and add new spare parts (default)

Documents

Document records attached to objects can be transferred between IFS/Asset Design and IFS/Equipment. The default value is to add new documents only.

System Variable	Value/Description
Documents from Design to Equipment Documents from Equipment to Design	1 = Replace the document list 2 = Add new documents only (default)

Object Connections

Objects related to the design or equipment object may be transferred between IFS/Asset Design and IFS/Equipment. The default value is to add only the non-existing object connections.

System Variable	Value/Description
Object Connections from Design to Equipment Object Connections from Equipment to Design	1 = Replace the object connection list 2 = Add new object connections only (default)
