Besides the PC elements, the function library consists of functional units. Functional units are
available to supplement the library for more complex functions. A functional unit is a package
of different program functions such as PC element, data base element and operator’s functions.
This simplifies the realization of combined functions with both the control function and
associated operator’s handling via a display screen and keyboard.
The application can be a closed loop control function or a motor or valve control function
requiring an advanced “face-plate” for the operator.
You can use several functional units in combination.
The functional units are also used individually. Examples of this can include a measuring circuit
with alarm activation/deactivation and display screen presentation or a simple command
function from the operator to the process.
You can freely combine the functional units with other PC elements.
Figure 1-43 illustrates the application of functional units in a complex burner control.
