Interfaces for communication via PROFINET and partially PROFIBUS DP are already integrated in the S7-1500 CPU. It is an advanced device that helps the programmable logic controller to use its potential as efficiently as possible, and was designed specifically to work with SIMATIC S7-1500 PLCs.

In a decentralized architecture with SIMATIC ET 200MP PtP communication modules, serial interfaces can be used for non-contact data transmission. Four PtP communication modules are available for connecting automation components via serial interfaces. Communication modules extend the range of total communication capabilities through additional functions and interfaces. SIMATIC ET 200MP IO-Link Master is based on the current IO-Link V1.1 specification. This means that when a device is replaced, the current parameters are automatically transferred to the new IO-Link device – without additional user intervention. A special feature of the SIMATIC ET 200MP IO-Link Master module makes it possible to replace the module, without using a programmer and without having to back up the data.

High Feature CM PtP Communication Module – 6ES7541-1AB00-0AB0 is an I/O system that can easily be used in a variety of applications, has an IP20 protection rating, and is designed to maximize application convenience and maximize functionality. The compact size of the device of this class is made possible by the high density of channels, the small size facilitates the use of the space saved inside the control cabinet. A special space for cable management ensures that a high level of aesthetics is maintained inside the control cabinet station.

SIMATIC ET 200 interface modules offer advanced functionality even without integrated CPUs. Advanced system PROFINET Shared Device provides distribution of large limits of one station configuration between 2 or 4 PROFINET IO controllers. Large configuration limits can be grouped behind an I/O module to link data to different controllers. This saves the installation of further interface modules and the associated costs.

The ET 200 supports all MSI and MSO functions. With MSI, data from a digital or analog input module can be mapped to up to four IO controllers. With MSO, data that the controller writes to a digital or analog output module can be read back by up to 3 additional IO controllers. In this way, MSI/MSO helps further save on unnecessary wiring. No programming of communication devices or other mechanisms is needed, it simplifies software engineering to the maximum, greatly improves the operation and maintenance of the user program. Changes and adjustments without problems can easily be made at any time without adversely affecting the user’s program.

With proximity detection on PROFINET (LLDP), ET 200 interface modules no longer require memory cards. This simplifies IM handling during replacement and also reduces costs. If the communicator fails, you can simply remove it and put in a new communicator. The IP address and new name are automatically assigned to the new module by proximity detection. The interface modules are integrated with TIA Portal. In addition, GSD files are available with which the interface modules can be integrated into any engineering tool and operated on any PROFINET-enabled controller. In particular, it makes it possible to optimize the cost of building small-scale stations.

The ET 200 is ideal for use in advanced plants with very high configuration limits. The connection to PROFINET and PROFIBUS allows installation centrally in a control cabinet or distribution in plants that may cover large areas. In addition to the basic features of SIMATIC I/O systems, additional enhanced variants of SIPLUS Extreme allow to increase the application sites of devices in hazardous areas, for example. The S7-1500 FAIL SAFE ET 200 modules enable the processing of both safety-related and standard programs. Their functional safety is certified in accordance with IEC 61508. They are designed for safety applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849.
