The purpose of this trace is to find a connected system whose boundary is a city gate (TBS) or a regulator. Possible uses of this ability include asset management, maintenance information, and inventory. You can designate Town Border Stations and Regulators. By default, only the Town Border Stations box is checked in the Analysis Options dialog.
For the Town Border Station option, the solver looks for junctions with Bit 21 (Town Border Station) set. For the Regulator option, the solver looks only for Bit 20 (Regulator) set.
Object Class Model Names: TBS, REGULATOR
Gas System Bit Interpretations
- Bit 18 - Specifies if the device is a gas system boundary. This bit setting depends on the existence of the following field model names: GASSYSTEMSTATUS and NORMALPOSITION.
- If NORMALPOSITION exists, this field value will be used to set the bit. A value of 1 means that it is not a boundary. A value of 0 means that it is a boundary.
- If NORMALPOSITION does not exist, the GASSYSTEMSTATUS field value will be used to set the bit. A value of 1 or Y means that it is a boundary. A value of 0 or N means that it is not a boundary.
- Bit 21 - This bit specifies if a device is a town border station and depends on the existence of the class model name TBS; 1 means that it is, 0 that it is not.
- Bit 20 - This bit specifies if a device is a regulator and depends on the existence of the class model name REGULATOR; 1 means that it is, 0 that it is not.
- Bit 25 - This trace does not traverse any edges for which bit 25 is set.
