HIMA F35 Controller

The HIMA F35, also cataloged as the F35 Safety-Related Controller, operates as a dedicated hardware component for high-integrity logic execution and field signal monitoring within HIMatrix safety platforms.

Suffix Breakdown & Model Matrix

• Base Configuration: Compact metal-enclosed processing unit.
• Programming Path: Supported by ELOP II Factory for system versions prior to 7; requires SILworX for system versions 7 and beyond.
• Memory Scaling: User program and data capacities vary by firmware revision, ranging from 500 kB (pre-v6.46) to 2047 kB (v6.100).

Hardware Specifications

Safety Control and SIS Characteristics

• SIL3 certification: The controller is engineered for integration into SIL3-rated safety loops, adhering to IEC 61508 standards for deterministic fault detection and safe-state logic processing.
• Triple modular redundancy (TMR) 2oo3 architecture: The F35 architecture supports integration into TMR-based safety fabrics, allowing for fault-tolerant execution where the controller maintains process safety despite internal hardware component discrepancies.
• Galvanic isolation: All signal interfaces, including the Ethernet and fieldbus ports, are designed with internal isolation to prevent the propagation of ground-loop noise and common-mode transients from the field environment into the safety processor.
• Fail-safe state execution: In the presence of internal system faults or loss of valid communication frames, the controller transitions to a pre-defined fail-safe state, ensuring that controlled process outputs remain in a secure condition.

Frequently Asked Questions

Q: How does the controller handle date/time retention during power cycles?

A: The F35 utilizes an integrated gold capacitor to buffer date and time data, providing short-term maintenance of the system clock during temporary power outages without requiring an external battery.

Q: Can the firmware be upgraded to support SILworX on older units?

A: Compatibility with SILworX is dependent on the installed operating system version. Units running versions prior to 7 require a specific upgrade path; verify your hardware revision and current OS compatibility before attempting a firmware flash.

Field Installation Guidelines

• Mounting: Secure the controller within an industrial enclosure rated at least IP20. Ensure the unit is mounted in a location that complies with the T4 temperature class for Zone 2 hazardous areas.
• Grounding: Bond the metallic enclosure to the cabinet's protective earth (PE) bus using the provided earthing screw. This connection is mandatory for maintaining electromagnetic immunity and protecting internal galvanic isolation circuits from static discharge.
• Wiring: Connect the 24 VDC power supply from a unit featuring safe insulation per IEC 61131-2. Maintain a minimum separation of 150 mm between all signal/Ethernet cabling and high-power conduits to prevent induced interference and communication latency.
