1. General Description

 

The Siemens 6ES7 158-0AD00-0XA0 is a PROFIBUS DP/DP Coupler designed to connect two separate PROFIBUS DP networks. It functions as an intelligent slave on both networks, allowing for deterministic data exchange between two different PROFIBUS masters (e.g., two separate PLCs).

This device is ideal for applications that require galvanic isolation between segments, coupling of networks from different machine manufacturers, or expanding a network beyond its normal physical limits. Data transfer is configured in STEP 7 or a similar engineering tool, where the I/O data to be exchanged is defined.

 

Key Features 🎯

 

• Network Coupling: Connects two independent PROFIBUS DP networks for data exchange.
• Dual Slave Operation: Acts as a slave device on both the primary and secondary PROFIBUS networks.
• Galvanic Isolation: Provides electrical isolation between the two connected networks, enhancing system stability.
• Addressable Slave: PROFIBUS address is set via DIL switches for easy configuration (0-126).
• Onboard Diagnostics: A dedicated DIL switch and LED indicators provide basic diagnostic information.
• Simple Data Exchange: Transparently transfers a configured amount of I/O data from one network to the other.
