15. SAT 3C/D/F INSTALLATION

Globally Addressable Control Points

Globally Addressable Control Points

The main differences between the different types of SAT 3C/D/F controllers primarily have to do with the amount of data from
the various TUC/RTU type controllers that then can be globally addressed to a logical control point within the existing satellite
data structure and then used within the WCC III system as a recognizable control point.

The SAT 3D controller can allow each TUC/VAVZ II controller to have up to 4 Analog logically addressable control point values
and 2 Binary logically addressable control point values that can be globally used within the WCC III program. These address-
able control points are “shoehorned” into the existing satellite data structure. As such, there can only be 32 TUC/VAVZ II type
controllers connected via the TUC communications loop to the SAT 3D controller. Each one of the SAT 3D controllers takes up 4
physical satellite addresses.

The SAT 3F controller can allow each TUC/VAVZ II controller to have up to 8 Analog logically addressable control point values
and 8 Binary logically addressable control point values that can be globally used within the WCC III program. These addressable
control points are “shoehorned” into the existing satellite data structure. As such, there can only be 16 TUC/VAVZ II type control-
lers connected via the TUC communications loop to the SAT 3F controller. Each one of the SAT 3F controllers takes up 4 physical
satellite addresses.

The SAT 3C controller can allow each RTU/TUC controller to have up to 32 Analog logically addressable control point values
and 48 Binary logically addressable control point values that can be globally used within the WCC III program. These addressable
control points are “shoehorned” into the existing satellite data structure. As such, there can only be 8 RTU/TUC type controllers
connected via the TUC communications loop to the SAT 3C controller. Each one of the SAT 3C controllers takes up 8 physical
satellite addresses.
