ABB PM891 3BSE053240R1｜Redundant Processor ｜
All components used in the system must be fully compatible with the FOUNDATION Fieldbus High Speed Ethernet (HSE) specification.
HSE utilizes a high-speed Ethernet backbone (typically 100 Mbit/s) and incorporates built-in redundancy. The HSE architecture is based on an enhanced IEEE 802.3 Ethernet model, with additional layers to support industrial communication requirements.
The HSE Application Layer includes support for:
DHCP – Dynamic Host Configuration Protocol
SNTP – Simple Network Time Protocol
SNMP – Simple Network Management Protocol
These services enable automated addressing, time synchronization, and network diagnostics across the HSE network.
System Data – High Speed Ethernet (HSE)

Linking Device – Functional Description
The Linking Device is designed according to Class 42c of the FOUNDATION Fieldbus HSE profile and provides the following functions:
Support for up to four FF-H1 links.
Each H1 link can operate with the Linking Device acting as both the Link Master and the Time Manager.
Device Identification
Automatically identifies all field devices connected to the FF-H1 segments.
Configuration via HSE
Provides System Management and Network Management functionality for configuring connected H1 devices through the HSE network.
Access to Function Blocks
Enables access to the function blocks of all connected H1 devices via HSE, simplifying system integration and control.
