Description

The Honeywell ICS Triplex T8800 is a high-availability Communication Gateway Module for Honeywell’s Trusted® Triple Modular Redundant (TMR) safety platform, enabling secure, deterministic data exchange between safety controllers (e.g., T8110B) and external systems like DCS, SCADA, or asset management platforms. Certified for SIL 2 applications per IEC 61508/61511, this module translates proprietary TMR bus protocols into industry-standard interfaces while maintaining electrical isolation and cybersecurity integrity. The ICS Triplex T8800 supports simultaneous communication over dual-redundant Ethernet ports with Modbus TCP, OPC DA/UA, and Honeywell’s Experion® PKS protocols, allowing real-time transfer of process values, alarms, and diagnostics without compromising safety functions.

Engineered for mission-critical environments, the module features triple-redundant processors that continuously synchronize and validate data packets. Its embedded firewall enforces IEC 62443-3-3 cybersecurity standards, blocking unauthorized access through role-based authentication and encrypted tunnels. The ICS Triplex T8800 operates across -40°C to +70°C with vibration resistance up to 5g RMS, making it ideal for offshore platforms, power plants, and chemical facilities where network reliability ensures uninterrupted safety system visibility.

Technical Specifications

Main Features and Advantages

Deterministic Data Exchange: The T8800 uses three independent ARM Cortex-A53 processors running in lockstep. Each processor validates message consistency before transmission, discarding packets with mismatched checksums. This TMR design ensures 99.999% communication availability even during single-channel faults, critical for real-time safety alerts in turbine control or wellhead monitoring.

Cybersecurity Hardening: An integrated stateful firewall inspects all traffic using deep packet inspection (DPI), blocking unauthorized commands. Role-based access control (RBAC) limits configuration changes to authorized engineers, while audit trails log all access attempts. The ICS Triplex T8800 supports hardware-trusted boot and signed firmware updates to prevent malware injection, meeting NERC CIP and IEC 62443 requirements for critical infrastructure.

Seamless System Integration: Native support for Experion® PKS enables plug-and-play integration with Honeywell DCS, exposing safety system diagnostics to operators. Simultaneous Modbus TCP/OPC UA connectivity allows bidirectional data flow with third-party PLCs or historians. The module’s dual-power domain design maintains communication during backplane power loss, leveraging capacitors for 50 ms graceful shutdown.

Application Field

The Honeywell ICS Triplex T8800 bridges safety and process networks in high-risk industries:

Oil & Gas: Integrates offshore ESD systems with central control rooms, transmitting valve statuses and gas detection alarms via satellite links.

Power Generation: Synchronizes turbine protection systems (T8110B) with plant DCS for coordinated trip responses during grid instability.

Chemical Processing: Streamlines batch reporting by transferring reactor safety interlocks to MES platforms via OPC UA.

LNG Terminals: Facilitates remote monitoring of cryogenic safety valves from onshore facilities using encrypted Modbus TCP.

Pharmaceutical: Enables FDA-compliant audit trails by logging safety system events to centralized databases.
