SqNode.PacketErrorRate

The packet error rate for the SynqNet node associated with the SqNode object.

Each SynqNet node has a packet error counter and a packet error rate counter. Packets addressed to a node are checked for integrity.

The packet error rate counters are used to trigger fault recovery and/or failure shutdown. The packet error rate counter is incremented for each missing or invalid packet and is decremented for 16 consecutive valid packets. Packet Error rates for a single network direction saturate at 255. The packet error rate counters can detect large errors over short periods of time or small errors over long periods of time.

This property cannot be saved to flash memory.
