The main components of the signal flow chart are generally the laboratory instruments, which are
initially displayed in the working area with blue functional units. Depending on the measuring task, the
laboratory instruments can be supplemented with virtual functional units (red, green, yellow) for
control, result display etc. Other components of the signal flow chart are the arrow connections, which
specify the signal flow between the respective functional units. The steps required to generate a signal
flow chart are listed below.
The basic operating sequence of the labworldsoft control and evaluation program is presented in the
following. Here a simple flow chart for a magnetic stirrer (e.g. RET control) is to be generated in which
the speed can be controlled and the actual measured value can be displayed. Following the
measurement the configuration is saved for later applications and printed out.

In the first step the functional units are pulled from the tool bar to the working area. In addition to the
laboratory instrument (blue), other functional units "slide controllers" (red) and "digital display" (green)
are also required. For the arrow connections (signal flow) later, functional units must also be suitably
positioned. Usually, a signal flow from left to right is selected.

In the second step the parameters of the functional units are set in the respective parameter window.
These include the port number (laboratory instrument only) for the RS-232 interface and the input and
output paths for the controlling variable or result type. After closing the parameter window, the paths
set appear as number fields on the related symbol of the working area. These act as anchor points for
the arrow connections.
