Description

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) dual-redundant 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 modules are connected to the primary port and the backup port of the slave device respectively. Two ALP121 modules function as the master device to communicate with slave devices, and exchange data with PROFIBUS-DP slave devices.
