Advantech’s newly released ECU-P1524PE expansion module, in line with IEC-62439 protocols, is to be built into its computing platforms to realize High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) with hardware without increasing CPU loading and offsetting computing efficiency. In this way, the product helps to achieve zero-loss redundancy and zero-time recovery, effectively enhancing network security and application performance.

HSR follows IEC 62439-3 Clause 5 and provides zero-loss redundancy. With a typical ring topology, HSR allows source nodes to duplicate all data frames and send them to destinations in either of two paths, so that it can achieve redundancy without the need to duplicate cables or switches. Thus, HSR is currently considered to be the most effective redundancy method available for wired Ethernet.

PRP follows IEC 62439-3 Clause 4 in providingzero-time recovery. A typical PRP topology is a double star, with each node connecting to two separate and parallel LANs. As its network loading will not increase with network scaling, PRP is considered to be an ideal choice for large-scale network requirements.

The ECU-P1524PE expansion module is an excellent match for Advantech’s dedicated power automation PCs. It is TUV IEC 61850-3 certified for ECU-4784 or UNO-4673A/4683 and provides a complete network redundancy solution. It adopts a Small Form-Factor Pluggable (SFP) module for hardware I/O design, supporting a variety of network interfaces including RJ-45 and single/multiple mode optical fiber, so that users can flexibly choose a suitable SFP module for each node to satisfy different application scenarios requirements.

For substations, users can choose SC or ST type I/O with improvedanti-interference capability, or they can choose single or multiple mode optical fiber communications, depending on data transmission distance.
