Logic blocks support drag and drop functionality. If the list of Logic blocks is too long to fit into the Logic block list area, use the scroll bar to expose additional blocks.

Logic blocks are not visible on the navigation tree. If the LCT window is not large enough to show all the logic blocks, you cannot scroll down to see the hidden blocks. To make sure you see them all, enlarge the panel displaying the logic by dragging the borders or reducing the number of panels.

See the following table for a list of Logic blocks.

Table 1. Logic Blocks
Logic Block Name	Description
Math	Performs mathematical functions on one or more inputs, producing a single output. 1–8 inputs
Bool	Performs Boolean functions on 2–8 inputs, producing a single output. This category also includes the Latch function.
Statistical	Performs statistical functions on 2–8 inputs producing a single output.
Selector	Performs multiplexing for 2–8 inputs, producing a single output. Based on the current mode assigned to each input, the selector chooses which input to pass through to the output.
Control	Performs control functions on three inputs, producing a single output.
Psychro (Psychrometric)	Performs psychrometric functions on the defined inputs, producing a single output.
Attributes	Gives the user the ability to expose values from within their control logic, either as an input or output. These blocks are considered attributes of the Program (Control System) Object in which they are included, and may be viewed or configured from the standard Focus view. A control system is limited to a combination of 24 inputs and 24 outputs. See the Program (Control System) Object for more information.
Constant	Passes a constant value to building block inputs.
Calculation	Controls the amount an output can change per control system execution or extrapolates an output using two inputs for reference.
Timing	Passes its input to its output at the next execution of the control system (every 5 seconds). Timing blocks are used to break up feedback loops. The Timing category also includes the Time and Timer blocks.
