SIEMENS 6ES7158-0AD01-0XA0

Siemens SIMATIC S7 DP/DP Coupler Module Description The 6ES7158-0AD01-0XA0 is a DP/DP coupler from Siemens, designed for the SIMATIC S7 family. This module serves as a crucial link between two independent PROFIBUS DP networks, allowing for fast and deterministic data exchange. It acts as a slave on both networks, enabling communication between two different DP master systems. This is particularly useful for modular machine designs or for connecting plant sections that operate on separate networks. Though now an obsolete item, it remains a vital component for maintaining and expanding existing PROFIBUS-based automation systems. Specifications Manufacturer: Siemens Product Type: DP/DP Coupler Part Number: 6ES7158-0AD01-0XA0 Power Supply: 24V DC Network Protocol: PROFIBUS DP Data Transfer Rate: Up to 12 Mbit/s (on both DP interfaces) I/O Data Size: Up to 244 bytes inputs and 244 bytes outputs Operating Temperature: 0 to 60 deg. C Label Info SIMATIC S7 6ES7 158-0AD01-0XA0 E-Stand: 04 Application This coupler is typically used in industrial automation to connect two PROFIBUS DP networks. Common applications include linking control systems of different machine builders, creating separate network segments for performance optimization, or coupling systems in large, distributed plants. Country of Origin Made in Germany. CO2 Impact Choosing this reused DP/DP coupler over a new one prevents the emission of approximately 12 kg of CO2. This saving is comparable to the energy needed to charge a modern smartphone over 1440 times. Availability This is an obsolete product but is available from our stock.

FAQ What is the maximum amount of data that can be transferred through the 6ES7158-0AD01-0XA0?The module can transfer a maximum of 244 bytes of input data and 244 bytes of output data. The data area can be configured in various sizes, up to 16 I/O modules of up to 16 bytes each. Is this DP/DP coupler compatible with any PROFIBUS DP master, or only with Siemens SIMATIC S7 PLCs?The DP/DP coupler is a standard PROFIBUS DP slave on both sides. Therefore, it is compatible with any controller that functions as a PROFIBUS DP master according to the EN 50170 standard, not just Siemens S7 PLCs. How is the DP/DP coupler configured and parameterized? Is special software required?Configuration is done within the hardware configuration tool of the DP master’s engineering software, such as SIMATIC Manager (for S7-300/400) or TIA Portal. A GSD (General Station Description) file for the coupler is required, which can be downloaded from the Siemens support website. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
