For reasons of consistency, the terms "device", "controller", and "supervisor" are used below.
The terms "slave" and "master" are only used in the PROFIBUS chapter and are still use
there.

● Drive unit (PROFIBUS: Slave, PROFINET IO: IO Device)
Example: Control Unit CUD
● Controller (PROFIBUS: Master Class 1, PROFINET IO: IO Controller)
A controller is typically a higher-level controller in which the automation program runs.
Example: SIMATIC S7 and SIMOTION
● Supervisor (PROFIBUS: Master Class 2, PROFINET IO: IO Supervisor)
Devices for configuring, commissioning, operating control and monitoring while the bus is
in operation
Devices that only exchange data with drive units and controllers acyclically.
Examples: Programming devices, human machine interfaces
