Application

Dual ethernet port link status (PRPSTATUS) together with IEC 62439-3 parallel redundancy
protocol (PRP) are used to supervise and assure redundant Ethernet communication over two
channels. This will secure data transfer even though one communication channel might not be
available for some reason. Together PRPSTATUS and PRP provide redundant communication
over station bus running IEC 61850-8-1 protocol. The redundant communication use both port
AB and CD on OEM module.
