Diagram

The function diagram is composed of up to 2048 units, local I/Os, variables and constants.
Elements are added to the diagram through the Toolbar. To select an element simply click on it.
The selection will be indicated through a blue shadow drawn around the element. By clicking
the Delete button in the toolbar or pressing the Delete key on your keyboard the selected
element can be deleted. To move an element on the diagram view drag it like shown in the
image below.

Each element has one or more ports through which it can be connected to other elements. Input
ports are displayed on the left side of the element, output ports on the right. Each port has one
of the following data types:
• Boolean [0..1]
• 8-bit unsigned integer [0..255]
• 8-bit signed integer [-128..127]
• 16-bit unsigned integer [0..65,535]
• 16-bit signed integer [-32,768..32,767
• 32-bit unsigned integer [0..4,294,967,295]
• 32-bit signed integer [-2,147,483,648..2,147,483,647]
• 32-bit floating point number
• 64-bit floating point number
• String (up to 4096 bytes)
Note that when data types are compared to each other, this will be done according to this
list. Boolean is considered the smallest data type, String is considered the greatest data type. If
ports with different data types are connected to each other, the value will be converted from the
output port's data type to the input port's data type implicitly. Note that this may lead to loss of
data. Open input ports are defined to have the value 0 (Boolean data type). To negate a port,
double-click on it. The negation will be indicated through a bubble as can be seen in the image
below. The negation is performed logically. A value of 0 will be negated to 1. A value unequal
to 0 will be negated to 0. Negating a string will result in an empty string.
