PROFINET Communication

Описание: In this video i will to show you how to configure the Tia Portal settings and some of the concepts of Profinet Communication.

There is more explanation if you want to know more about this. Iwill put more videos.

PROFINET IO is a real-time protocol based on Ethernet. It is used as a high-capacity network for industrial automation applications. The PROFINET IO protocol facilitates the exchange of data with a programmable logic controller (PLC). A PROFINET IO network consists of the following devices:

IO Controller: Usually the PLC, which manages the overall application.

IO Device: A decentralized IO device (e.g., an encoder or a sensor) controlled by the IO Controller.

IO Supervisor: An HMI (Human-Machine Interface) or PC used for diagnostics or commissioning purposes.

Real-Time Communication Modes

PROFINET provides two types of real-time communication:

PROFINET IO RT (Real-Time):

Real-time data is transmitted via a prioritized Ethernet frame.

No specific hardware is required.

Cycle times as low as 4 ms can be achieved due to frame prioritization.

PROFINET IO IRT (Isochronous Real-Time):

Designed for applications with stricter timing requirements.
Achieves cycle times of up to 2 ms.

Requires specific hardware for switches and IO devices.

Non-Real-Time Communication

All diagnostic and configuration data is transmitted through a non-real-time (NRT) channel using a standard TCP/IP protocol. However, no guaranteed delay can be provided, and typical cycle times can exceed 100 ms.
