Topology with foresight Data transmission via Ethernet in the process industry creates new opportunities Until now, the opportunities to use PCs or remote solutions in the process industry were extremely limited for technical reasons. One of the interesting alternatives to the solutions used to date is to transfer data via Ethernet. Unlike classic visualization concepts, the maximum transfer distances are greater and the topology is simpler and more flexible because the visualization platform becomes just another normal network component. Andreas Grimsehl As flexible as any other network...

The limitations of classic data transfer Using as few components as possible and long data transfer links - these apparently contradictory requirements cannot be met with the usual PC video interfaces. They can be used to bridge only a few meters without additional components. On the other hand, KVM amplifiers enable data to be transferred for a few hundred meters. However, analog signal transfer is susceptible to interference. This problem can be solved by digitizing data transfer. Until now, project managers had no choice other than to try to find a compromise between a small number of...

�������������� ������������������ Fig. 4: There is an unmistakable trend towards the decentralization of monitoring and control tasks. Process visualization in the field is becoming more commonplace. ring reliability meant installing an A/D and D/A converter at the beginning and end of a transfer link. Data transfer via the Ethernet is less susceptible to faults because purely digital data transfer is possible without these additional components. The visualization platform is clearly identified and managed with its IP address, making it a “perfectly normal” network component. This is...
