Core Functionality

Communication Offloading
Independently manages PROFIBUS DP communication, relieving the main safety CPU from bus processing tasks. This improves system real-time performance, determinism, and overall reliability.

Safety-Compliant Architecture
Works in coordination with the main safety CPU to ensure secure communication paths and compliance with SIL 3 safety requirements for SIS and ESD applications.

Diagnostics & Maintenance

Real-time monitoring of PROFIBUS bus status

Detection and reporting of communication faults

Supports online diagnostics and hot-swappable replacement, minimizing downtime

Remote Configuration
Supports ELOP II remote programming and configuration via Ethernet (version V4.1 and above), enabling centralized engineering and maintenance.

Typical Applications

Used in SIS / ESD systems across high-risk industries, including:

Petrochemical and chemical processing

Offshore oil and gas

Power generation

Metallurgy and heavy industry

Typical use cases include secure PROFIBUS DP communication between the HIMA safety system and:

DCS

SCADA systems

Field instruments and remote I/O stations
