A Custom Expression Block In Detail

• Color — The color on the left side of the block indicated what type of block it is (red for input blocks, orange for processors, purple for Custom Expressions and green for the output block).
• Name — The name of the block.
• Value Or State — The value of an input block (as defined with the input simulator, shown in a blue field) or the output value or state of a processor block (shown in a green field).
• Description/Parameters Button — Click the pencil button to enter the parameters and to view a description of the block.
• Connectors — Use the connectors to connect the block to other blocks. Input blocks have one output connector. Processors have one or more input connectors and one output connector. When you hover with your mouse over a connector, you can see what type of input is required and how many inputs are allowed (for an input connector) and what type of output it has and how many output connections are allowed (for an output connector). To make a connection, drag with your mouse from one connector to the other. To delete a connection, hover with your mouse over it until it becomes green and then click.

Note

A block gets the label 'skipped' (in an orange field) if its value or state is not taken into account when calculating the output value of the Custom Expression. For instance, because one (or more) of its own input or output connections are missing or because a connection further down in the definition is missing.
