The protocol classifies devices into IO controllers, IO supervisorsand IO devices, which have a specific collection of services.PROFINET IO uses three different communication channels to exchange data. The standard UDP/IP and TCP/IPchannel is used for parameterization and configuration of devices and for acyclic operations. The Real Time (RT)channel is used for cyclic data transfer and alarms. The third channel, Isochronous Real Time (IRT) channel, isused e.g. in motion control applications (not implemented in SI-EP3).PROFINET IO devices are structured in slots and sub-slots, which can contain modules and sub-modulescorrespondingly. Devices can have almost any number of slots and sub-slots and they can be virtual or real.Device specific data is represented in slot 0, module and sub-module specific data in subsequent slots and sub-slots.
