Take a home automation system as an example: You may talk with your router, your heating-system, your solar-inverter, some ip-cameras ..., where all of this are part of a CSP. The communication may run over classic fieldbus systems, over rest interface or more generally speaking over TCP/IP. Some routers allow you to reach a lot of IoT devices over wireless connections. The heating system also provides sensors and allows to receive setpoints as output.
