The following diagram depicts the main pieces of equipment, OT devices, networks, and protocols involved in the I-IoT data flow. These are arranged according to their hierarchical structure in the CIM pyramid, as we have already seen in previous chapters:
We will emphasize here that this logical schema is not a complete picture of all of the equipment, devices, networks, and protocols that we have in an industrial plant—nor is it the only possible representation of their interactions and interconnections. As we mentioned in previous chapters, there is no such precise and clear-cut separation of functionalities and devices between CIM levels in the real industrial world. Some devices placed in one particular level can be deployed to an upper or lower level with an enlarged or restricted scope...
