Visualisation |
When designing a process network, some questions may come up:
The behaviour of a process network can be very complex because of the parallel execution of the processes.
Often it is not easy to know what will happen during the execution. Answering the questions above
without an appropriate simulation is often unfeasible.
By means of this training module you can execute a developed process network example
and observe the actions via an adequate visualisation.
After the start of the visualisation each process executes its substeps one by one.
During the execution the process network itself is not editable. Therefore the
functionality for e.g. adding a process, buffer or arrow are disabled.
After the termination of the execution these items will be enabled again.

The visualisation bases on time steps.
A time step is the elementary time unit of the training module and can be interpreted as second
or minute depending on current context. The visualisation shows the current state of the processes
and FIFO buffers after each time step. The elapsed time steps are visualised by a digital clock in
the upper right corner of the network editor (see Figure 21).
The state of a process consists of the currently executed substep. The state of a buffer is repesented
by its current content.
Within this training module there are two different kinds of visualisation flows. You have the
choice between
a stepwise or continuous visualisation. The stepwise visualisation bases on the time steps
and stops after each time step.
In the following subsection you can learn how you can start and control the visualisation in this
training module.
