Overview:Network variable type.. Network variable type description for network variables that support changeable types.
This SNVT specifies the type of a network variable. A SNVT_nv_type network variable can be used to create a configuration network variable that specifies the type of a second network variable. The configuration network variable must be declared as a SCPTnvType configuration property. A SCPTnvType configuration property may also be declared within a configuration file, not using the SNVT_nv_type type. See the SCPTnvType description for further details on using this SCPT.
The type_scope field contains the scope of the resource file that defines the specified type. The scope may be any of the following values:
| 0 |
= |
Standard – applies to all devices. |
| 1 |
= |
Reserved for future use. |
| 2 |
= |
Reserved for future use. |
| 3 |
= |
Manufacturer – applies to all devices from the manufacturer specified in the program ID template. |
| 4 |
= |
Manufacturer and Device Class – applies to all devices from the manufacturer with the device class specified in the program ID template. |
| 5 |
= |
Manufacturer, Device Class, and Device Subclass – applies to all devices from the manufacturer with the device class and device subclass specified in the program ID template. |
| 6 |
= |
Manufacturer, Device Class, Device Subclass, and Device Model – applies to all devices of the specified type and manufacturer specified in the program ID template. |
