Product Introduction
The ABB CI858K01 (3BSE018135R1) is a high-availability PROFIBUS DP-V1 communication interface engineered for ABB’s AC 800M High Integrity Controller platform. Designed for mission-critical automation, this module bridges AC 800M controllers with PROFIBUS DP field devices while delivering deterministic data exchange essential for safety systems. The ABB CI858K01 operates in Class 1 Master, Slave, or DPV1 modes, enabling seamless integration of drives, I/O subsystems, and intelligent instruments into ABB’s 800xA DCS architecture.
Featuring dual-redundant RS-485 ports with galvanic isolation, this module ensures continuous communication during cable faults or electromagnetic interference. Its SIL 3 certification allows deployment in safety instrumented systems (SIS), while integrated diagnostic buffers capture network events with microsecond timestamps for rapid troubleshooting. For industries demanding uncompromised reliability, the CI858K01 delivers military-grade resilience with DNV GL maritime and ATEX hazardous area certifications.
Core Advantages and Technical Highlights
Deterministic Performance:
Hardware-based PROFIBUS ASIC achieves 12 Mbps data rates with jitter <1µs. Supports 244-byte input/output data per node – 3× industry standard capacity.
Functional Safety Integration:
SIL 3 certification via redundant microprocessors with cyclic self-tests. Native PROFIsafe support enables safety I/O integration without gateways.
Network Resilience:
Automatic switchover (<100 ms) in redundant pairs during fiber breaks or power loss. Optical isolation (1500 VAC) prevents ground loops.
Advanced Diagnostics:
Embedded web server provides real-time bus statistics (telegram error rate, node status). SNMP v3 traps forward alerts to central monitoring systems.
Cybersecurity Hardened:
MAC address lockdown and VLAN tagging (IEEE 802.1Q) segment network traffic. Secure boot with cryptographic signature validation.
Typical Application Scenarios
In offshore FPSO vessels, redundant ABB CI858K01 pairs network subsea safety valves via PROFIBUS PA segment couplers. DNV GL certification ensures operation in corrosive marine environments, while SIL 3 compliance meets API 14C safety requirements for emergency shutdown systems.
Power plant turbine control systems leverage the module to synchronize governor actuators across redundant PROFIBUS rings. The -40°C cold-start capability maintains grid stability during winter storms, with optical isolation eliminating ground potential differences between turbine islands.
Pharmaceutical batch reactors utilize DPV1 mode for non-intrusive device calibration during CIP cycles. ATEX Zone 2 certification allows installation near solvent handling areas while PROFIsafe integrates flameproof temperature sensors.
