PLC-Application Examples Part B

Postprocessing Using NETQUEST

In an additional sixth step, the layer is saved as a bitmap or text file. The (previously developed) tool NETQUEST combines all layers, assigning the respective costs per meter for the construction of a fiber optic network. In this case, the classes shown in Table 5.2 were used.

The visualization of this information can be displayed in 2D and 3D images, shown in Figure 5.81. For the final results, NETQUEST uses this information for the calculation of a cost-optimized fiber optic network.

The Challenge

The students' feedback for the courses at the Carinthia Tech Institute is realized with a feedback form. The evaluation of this form is quite expendable, because it has to be done manually. Afterwards, these values have to be manually transferred into a PC software to get valuable statistical results.
