HIMA F8621X

Product Name: Ethernet Communication Module (HIMA F86 Series)

Product Introduction: The HIMA F8621X is an industrial Ethernet communication module within the HIMA F8 platform, designed to bridge safety controllers with higher-level MES/SCADA systems and support various industrial TCP/IP protocols.

Category: HIMA

Description

Technical Specifications:

Model: F8621X
Manufacturer: HIMA Paul Hildebrandt GmbH + Co KG
Communication Ports: Typically 2 × Ethernet (RJ45, 10/100 Mbps)
Supported Protocols: Modbus TCP/IP, OPC UA, ELOP II TCP, SafeEthernet, PROFIsafe
Processor: Dual Intel 386EX (32-bit, 25MHz) or equivalent safety microcontroller
Memory: 1MB Flash, 1MB SRAM, 1MB user program space
Supply Voltage: 24V DC (nominal)
Power Consumption: Approx. 6W typical
Safety Grade: SIL 3 (IEC 61508), PL e Cat.4 (ISO 13849)
Operating Temperature: -20°C to +60°C
Storage Temperature: -40°C to +85°C
Humidity: 5% to 95% (non-condensing)
Protection: IP54 (with casing) / IP20 (module only)

Functional Features:

Redundancy: Dual-processor “mirror-brain” architecture for synchronous comparison.
Security: Data encryption, authentication, access control lists.
Diagnostics: Comprehensive status reporting via SNMP/Modbus diagnostics registers.
Remote Access: Supports PC-based remote monitoring and parameterization.

Performance Parameters:

Throughput: Low latency millisecond-grade deterministic transfer.
Compatibility: Interfaces with HIMA F8650X/F8652X CPUs.

Material Composition:

Casing: Aluminum alloy shield (EMI/RFI suppression) + flame-retardant polymer front.
PCB: Conformal coated industrial grade.

Structural Features:

Mounting: Rack-mounted in HIMA F8 chassis.
Indicators: Link/Activity/Speed LEDs per port.

Working Principle:

The module processes Ethernet frames via a dual-core processor executing parallel checksum and logic validation. Safety data is wrapped in SafeEthernet frames with sequence counters and CRC. Upon receiving packets, the module validates source identity and timing before passing verified data to the safety CPU.

Advantages:

Single module handles both standard and safety communication (black-channel principle).
ATEX/IECEx option for Zone 0 hazardous areas.
High MTBF due to solid-state design and thermal-rated capacitors.

Applicable Industries:

Chemical, Oil & Gas, Pharmaceutical, Power Distribution, Hydrogen production facilities.

Model Series: HIMA F8627, F8627X, F8621A, F8621X (Evolutionary F8 comms line).

Installation Requirements:

Secure in F8 rack slot; ensure backplane connector alignment.
Use shielded CAT5e/6 cable (SF/UTP) for Ethernet runs.
Ground shield at one end (controller side) only.

Usage Precautions:

Configure firewall rules to restrict unauthorized IP access.
Firmware updates must be performed with system in maintenance mode to avoid safety disruption.
Avoid bending RJ45 cables at sharp angles to preserve pair twist integrity.
