PROFINET IO

Within the framework of PROFINET, PROFINET IO is a communication concept for the implementation of modular, distributed applications.

PROFINET IO allows you to create automation solutions, which are familiar to you from

PROFIBUS.

That is, you have the same application view in STEP 7, regardless of whether you configure PROFINET or PROFIBUS devices.

PROFINET IO Controller

Device via which the connected IO devices are addressed. This means that the IO controller exchanges input and output signals with assigned field devices. The IO controller is often the controller on which the automation program runs.

Programming device

Basically speaking, PGs are compact and portable PCs which are suitable for industrial applications. Their distinguishing feature is the special hardware and software for SIMATIC programmable logic controllers.
