SIMATIC ET 200 distributed I/O

SIMATIC ET200 – offers the right solution for every application

SIMATIC ET 200 offers a broad range of distributed I/O systems - for solutions in the control cabinet or without a control cabinet directly at the machine and for applications in hazardous areas. Thanks to their modular design, ET 200 systems are easy to scale and expand in small steps. Ready integrated add-on modules reduce costs while at the same time offering extremely diverse application potential. A huge range of different combinations can be selected: Digital and analog inputs/outputs, intelligent modules with CPU functionality, safety engineering, motor starters, pneumatic systems, frequency converters and a variety of technology modules, e.g. for counting and positioning tasks.

The communication via PROFIBUS and PROFINET, the uniform engineering, the user-friendly diagnostic tools and the optimum interfacing with SIMATIC controllers and HMI equipment are all proof of the unique consistency of the Totally Integrated Automation.

PROFIBUS

PROFIBUS is the international standard (IEC 1158/61784) for the field level. It is the only fieldbus to allow communication both in manufacturing applications and in process-oriented applications.

PROFIBUS is used to connect field devices such as distributed I/O devices or drives to automation systems such as SIMATIC S7, SIMOTION, SINUMERIK or PCs.

PROFIBUS is standardized in accordance with IEC 61158 and is a powerful, open and rugged fieldbus system with short response times. PROFIBUS is available in different forms for various applications.

PROFIBUS DP (distributed I/O)

PROFIBUS DP is used for connecting distributed field devices, e.g. SIMATIC ET 200 or drives, with extremely fast response times. PROFIBUS DP is used when actuators/sensors are distributed at the machine or in the plant, e.g. at field level.

PROFINET

PROFINET is the open, cross-vendor Industrial Ethernet standard (IEC 61158/61784) for automation.

Based on Industrial Ethernet, PROFINET enables direct communication between field devices (IO devices) and controllers (IO controllers), up to and including the solution of isochronous drive controls for motion control applications.

As PROFINET is based on Standard Ethernet according to IEEE 802.3, any devices from the field level to the management level can be connected.

In this way, PROFINET enables system-wide communication, supports plant-wide engineering and applies IT standards, such as Webserver or FTP, right down to field level. Tried and tested fieldbus systems, such as PROFIBUS or AS-Interface, can be easily integrated without any modification to the existing devices.
