ABB PNI800 Process Network Interface Module

ABB PNI800 (PN800 Factory Network Interface Module)
PNI800 is ABB Ability ™ Symphony ® The dedicated PN800 process network interface module of Plus DCS is designed to connect PC workstations to the PN800 real-time control network, enabling bidirectional real-time communication between engineer stations/operation stations and HC800/CP800 controllers. It is expected to be available for sale in 2026.

3、 Core Function (Key)
PN800 network access (mandatory)
Any PC (engineer station, operator station, OPC server) that needs to connect to the PN800 factory network must be equipped with PNI800, otherwise it cannot communicate with the HC800/CP800 controller.
Real time bidirectional data exchange
Upstream: Controller → PC (real-time process data, alarms, events, trends)
Downward: PC → Controller (configuration download, parameter modification, remote operation)
Speed: 100 Mbps, low latency, supports 5000+I/O real-time refresh
Dual network redundancy (PRP protocol)
The dual Ethernet ports support PN800 A/B parallel redundancy (PRP), enabling seamless switching (<100 ms) in case of network failure, eliminating single point of failure.
protocol support
System protocol: PN800 (Symphony Plus proprietary real-time protocol)
Compatibility: Can be converted to Modbus TCP, OPC UA, PROFINET, etc. with CP800
Diagnosis and maintenance
Panel LED status lights (power, network, communication, fault)
S+Engineering software online diagnosis, firmware upgrade, network status monitoring
4、 Typical application scenarios
Industry: Electric Power (Thermal Power/Hydroelectric/Nuclear Power), Oil and Gas, Chemical Industry, Water Treatment, Metallurgy
System: Symphony Plus (HPC800) DCS
role
Engineer Station: Configuration, Debugging, and Maintenance of HC800/CP800
Operator station: real-time monitoring, process operation, alarm processing
OPC Server: Provides data to upper level MES/ERP
Remote maintenance station: Remote access to PN800 network controller
5、 PNI800 vs CP800 (easy to distinguish)
PNI800: PC side interface – allows the computer to connect to the PN800 network (equivalent to a “network card”)
CP800: Controller side interface – connect HC800 to PN800 network+external multi protocol gateway
Relationship: PNI800 (PC) ↔ PN800 network ↔ CP800 (HC800 controller)
