30 |
Specifies the device status. The gas devices can be either open or closed. The value of 1 means that the device is closed (gas cannot flow through it). The value of 0 means that the device is open (gas can flow through it). |
|
29 |
Specifies if a device is a valve. The value of 1 means that it is. The value of 0 means that it is not. |
|
28 |
Specifies if a device is an essential valve. |
|
27 |
Specifies if a device is a non-controllable fitting and depends on the existence of the class model name NONCONTROLFITTING. Non-controllable is a fitting that cannot be used to shut off gas; 1 means that it is, 0 that it is not. |
|
26 |
Specifies if a device is a controllable fitting and depends on the existence of the class model name CONTROLFITTING. Controllable fitting is a fitting that can be used to shut off gas. It serves as a stop in a gas trace; 1 means that it is, 0 that it is not. |
|
25 |
Specifies if a device is a rectifier and depends on the existence of the class model name RECTIFIER; 1 means that it is, 0 it is not. |
|
24 - 22 |
Used to specify the isolation level to which a device belongs. Not currently used by ArcFM. |
|
21 |
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. |
|
20 |
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. |
|
19 |
Specifies whether a device is a CP barrier. The Cathodic Protection Trace tool traces in all directions until it encounters a junction feature on which bit 19 is set (or an edge feature on which bit 23 is set). Assigned gas autoupdaters and the Initialize Trace Weights command set bit 19 when encountering certain values associated with four model names, which are processed consecutively:

|
18 |
Specifies if the device is a gas system boundary (most likely a town border station) and depends on the existence of the field model names NORMALPOSITION or GASSYSTEMSTATUS. 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, GASSYSTEMSTATUS 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. |
|
17 |
Specifies if the device is a gas pressure system boundary. The gas pressure system is the system operating under the same pressure. Regulators are an example of the pressure system boundary. This bit setting depends on the existence of the following field model names: GASPRESSURESYSTEMSTATUS, NORMALPOSITION, SOPIN, and SOPOUT. If NORMALPOSITION exists, this field value will be used to set the bit. A value of 1 means that it is a boundary. A value of 0 means that it is not a boundary. If NORMALPOSITION does not exist, GASPRESSURESYSTEMSTATUS will be used to set the bit. A value of 1 means that it is a boundary. A value of 0 means that it is not a boundary. If GASPRESSURESYSTEMSTATUS does not exist, ArcFM then looks for both SOPIN and SOPOUT. If both field model names are found, ArcFM compares the values of their fields: if the values are different, then the bit is set. If the values are the same, the bit is not set; 1 means that it is a boundary, 0 that it is not. |

16 |
Specifies if the device is an emergency isolation system boundary and depends on the existence of the field model name EMERISOLATIONSYSSTATUS; 1 means that it is, 0 that it is not. This functionality is reserved for future use; it is not currently implemented. |
|
15 |
Specifies if the device is a squeeze off point; a value of 1 means that it is, 0 that it is not. |
