Siemens SIMATIC ET 200iSP User Manual

1.3 ET 200iSP station on PROFINET IO
PROFINET IO
PROcess FIeld NETwork
Open Industrial Ethernet standard which continues PROFIBUS and Industrial Ethernet. A cross-
manufacturer communication, automation and engineering model by PROFIBUS International
e.V., de󹪝ned as an automation standard.
PROFINET IO
Communication concept for the implementation of modular, distributed applications within the
scope of PROFINET.
PROFINET IO controller
Device via which connected IO devices are addressed. This means that the IO controller
exchanges input and output signals with assigned I/O devices. The CPU is often an IO controller.
PROFINET IO device
Distributed 󹪝eld device that can be assigned to one or more IO controllers, for example,
distributed I/O system, valve terminals, frequency converters, switches.
Intrinsic safety
The basis for intrinsic safety is the connection of the station via intrinsically safe 󹪝ber-optic
cables.
The optical transceiver on the media converter or on the switch must be approved for ATEX/IECEx
Zone 1.
PROFINET IO controller and IO device
The PROFINET IO controller is the communications interface of the control CPU. The PROFINET IO
controller exchanges data with the distributed I/O devices via PROFINET IO and monitors the
PROFINET IO. A distributed I/O device with PROFINET IO interface is an IO device. The interface
of the IO device in the ET 200iSP is located in the interface module.
The distributed I/O devices prepare the data of the encoders and actuators on site so that the
control CPU can process the data.
Devices that can be connected to PROFINET devices
A large variety of devices can be connected to the PROFINET IO – provided they behave according
to the standard IEC 61158-6-10:2019.
Devices of the following product families can be used:
• SIMATIC stations
• SIMATIC engineering stations and engineering PCs
• SIMATIC HMI (operator control and monitoring devices)
• Distributed I/O stations
• Devices from other manufacturers
