At the lower levels, we have a large amount of simple information that must be transferred within small and predefined deterministic time intervals. At the higher levels, the requirement is to transfer much more complex information within time intervals that do not need to be deterministic. So, in an integrated production system, different types of communication networks are required, each one specialized for the task to which it is dedicated. With regards to the CIM pyramid, we have the following networks:
Field or fieldbus networks were introduced for interfacing control devices, sensors, and actuators, reducing the need for complex wiring. In the ...
