The interface module (IM) connects the SIMATIC ET 200 to PROFINET or PROFIBUS – exchanging data between the controller and I/O modules. The modules are characterized by high channel density and low component variability, which significantly simplifies procurement, logistics or spare parts inventory.
The main difference between binary and analog interfaces is that an analog input receives signals with variable values, while a binary input receives signals with fixed static values.
ET 200S HF- 6ES7521-1BL00-0AB0 is a modular I/O system that can easily be used in a variety of applications, has an IP20 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.
25mm and 35mm module versions are available. Basic(BA), Standard (ST) and High Feature (HF) are available for connecting PROFINET interface modules alone. High Feature modules with enhanced functionality are available in 35mm format. The narrower 25mm modules use a front connector with push-in technology. Both versions of the modules have the same mechanical structure, offer the same functionality and the same accessories. 25 mm modules can be freely mixed with 35 mm modules
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.
