Plant and machinery are becoming increasingly modular. This means that they are being segregated into mechatronic units with separate functions. In a concept such as this, the electrical engineering follows the mechanical structure of the machine, bringing wide-ranging benefi ts. Once the machine modules have been developed they can be reused in various machines, which ultimately reduces the development effort. Modules can also be manufactured separately and joined together only during final assembly. What's more, modules can be developed in isolation from each other, so tasks can be run in parallel, saving time during development.
This type of engineering follows the building-block principle and enables customized solutions to be implemented at lower cost. Current fieldbus systems prevent this modular approach, as they are mainly based on a centralized master/slave approach. In safety technology in particular, one central instance is usually available: the master.
The publisher/subscriber communication principle applied universally on SafetyNET p does not use a central instance, thereby enabling a modular machine design.
