Description:
Dual-redundant network configuration
Both ALP121 modules and the communication interface between the PROFIBUS-DP network and the slave devices can also be in dual-redundant configuration. By segmenting the two ALP121 PROFIBUS-DP networks, the network itself can be made dual-redundant. In order to implement dual-redundant network configuration, PNO (*1) dualredundant slave devices (*2) are required.
A PNO dual-redundant slave device has 2 ports - primary and backup. The control side ALP121 module and the stand-by side ALP121 module are connected to the primary port and the backup port of the slave device respectively
Feature:
Multi-Protocol Support: Compatible with various industrial communication protocols for flexible integration with different control systems and devices.
Reliable Data Exchange: Ensures stable and secure communication between field devices and control systems for continuous operation.
High-Speed Communication: Provides fast data transfer, reducing latency and improving system response times in automation setups.
Seamless Integration: Easily integrates into existing automation systems, offering enhanced connectivity and interoperability.
Compact Design: Space-efficient, allowing easy installation in control panels or automation systems with limited space.
