PN800 Network Features

The PNI800 supports the ABB PN800 Plant Network, a high-speed redundant Ethernet control network.

Key features:

100 Mbps Ethernet communication
Dual network connection
IEC 62439 Parallel Redundancy Protocol (PRP) support
Zero-time network failover capability
Elimination of single points of network failure

The redundant network architecture consists of:

PN800A LAN
PN800B LAN

The PNI800 operates as a Dual Attached Node for PRP (DANP), connecting simultaneously to both redundant networks.
