Implementation of the PROFINET device model in SIMATIC

Slots and modules

A PROFINET device can have a modular and compact structure. A modular PROFINET

device consists of slots into which the modules are inserted. The modules have channels

which are used to read and output process signals. A compact device has the same design

and can include modules, however, it cannot be physically expanded, which means that no

modules can be inserted.

This is illustrated by the following graphic.

A module can contain multiple submodules.
