Derived function block Procedure Different block types are used in Unity Pro The general term for all block types is FFB There are the following types of block Elementary Function EF Elementary Function Block EFB Derived Function Block DFB Procedure Elementary functions EF have no internal status If the input values are the same the value at the output is the same for all executions of the function e g the addition of two values gives the same result at every execution An elementary function is represented in the graphical languages FDB and LD as a block frame with inputs and an output The inputs are always represented on the left and the outputs always on the right of the frame The name of the function i e the function type is shown in the center of the frame The number of inputs can be increased with some elementary functions Elementary function blocks EFB have an internal status If the inputs have the same values the value on the output can have another value during the individual executions For example with a counter the value on the output is incremented An elementary function block is represented in the graphical languages FDB and LD as a block frame with inputs and outputs The inputs are always represented on the left and the outputs always on the right of the frame The name of the function block i e the function block type is shown in the center of the frame The instance name
