HIMA F8650X The central processing unit (CPU) module of the safety instrumented system (SIS)

HIMA F8650X is a central processing unit (CPU) module for safety instrument-based systems (SIS). It adopts a redundant design to ensure the high reliability and safety of the system. It complies with the IEC 61508 standard and is suitable for the safety integrity level of SIL 3. The following is its detailed introduction:

Processor architecture: It adopts a dual-core Intel 386EX microprocessor, 32-bit, with a main frequency of 25MHz. It supports task-level redundant synchronization, and the handover time in case of single-core failure is less than 50ms.

Memory configuration: 1MB Flash-EPROM is used for storing the operating system and user programs, 1MB SRAM is used for data storage, supports hot backup redundancy, and the data synchronization cycle of the master and slave cpus is less than 10ms.

Communication interface: 2 RS-485 serial interfaces, electrical isolation, optional baud rates of 9600/57600bps, supporting Modbus RTU/ASCII protocols; Reserve the Ethernet expansion interface and it needs to be paired with the F8627X communication module to support the Modbus TCP/IP protocol.

Electrical parameters: Powered by 5V DC, peak power consumption 10W, built-in overvoltage/overcurrent protection circuit, working voltage range 4.75V - 5.25V.

Environmental adaptability: Operating temperature -20 ℃ to + 60℃, IP20 protection grade, anti-electromagnetic interference grade EN 61000-6-2 (Level 4), can withstand 95% humidity and strong vibration environment.

Redundant design

Processor redundancy: Dual-core cpus run the same control logic synchronously, monitor each other's status in real time through heartbeat signals, and seamlessly switch in case of single-core failure, with system availability reaching 99.9999%.

Communication link redundancy: The RS-485 interface supports dual-channel hot standby. When the main channel fails, it automatically switches to the standby channel, with a switching delay of less than 10ms.

Power redundancy: Supports dual power input. When the main power fails, the backup power seamlessly takes over, and the power switching time is less than 1ms.

Safety function:

Hardware self-check: When powered on, it automatically detects the status of the CPU, memory, and communication interface. In case of a fault, it outputs an error code through the 4-bit matrix display screen.

Software Watchdog: Built-in security watchdog, automatically resets the CPU when the program runs away, and the reset time can be configured.

Data verification: The CRC-16 verification algorithm is adopted to verify the integrity of the program storage area and the data storage area in real time. When an error is detected, it is automatically restored from the backup area.

Programming and Extension

Programming language: Supports IEC 61131-3 standard ladder diagram (LD), Structured Text (ST), and Function Block Diagram (FBD), and is compatible with mainstream development environments such as STEP 7 and CODESYS.

I/O expansion: It can be expanded to 2048 digital input/output points and 512 analog input/output points via the HIMA H51q bus.

Protocol compatibility: Supports mainstream industrial protocols such as Modbus, PROFIBUS-DP, and CANopen, and can be seamlessly integrated into equipment from manufacturers like Siemens, Schneider, and ABB.

The F8650X is widely used in fields such as industrial automation, petrochemicals, power, chemical engineering, metallurgy, rail transit, and automotive manufacturing. Its specific applications include emergency stop systems, fire alarm systems, gas leakage detection systems, and safety interlock systems, etc

Hot Module

• F8627X Communication Module: The F8650X has a reserved Ethernet expansion interface, which needs to be used with the F8627X communication module to support the Modbus TCP/IP protocol, enabling Ethernet - based communication and connection with other devices or systems5.
• Input/Output Modules: Such as the F3236 digital input module, F3330 digital output module, and F6217 analog input module7. These modules can be expanded through the HIMA H51q bus and work together with the F8650X CPU module to complete the acquisition, processing, and output control of various field signals5.
• H41q/H51q Series Modules: The F8650X belongs to the H41q/H51q series4. In the H41q - HSPES system, a coprocessor module can be installed next to the central module, which includes components such as a microprocessor HD64180 with a clock frequency of 10MHz, an operating system EPROM, two RS485 interfaces, and a dual - port RAM (DPR) for communication with the central module through the CPU bus1. These modules are related to the F8650X in terms of system architecture and function, and jointly complete the safety control and monitoring functions of the system.

The main reasons for choosing the HIMA system are as follows:

Technological leadership: HIMA was founded in 1908. Since it produced the world's first TUV-certified fault-safe control system Planar in 1970, it has always been at the forefront of the safety control field, guiding the development of four generations of global safety systems. Its Functional Safety center has several TUV-certified functional safety experts and a high-level R&D team. It invests 15% of its annual sales revenue in R&D, constantly exploring new fields of functional safety technology, and based on this, has established a series of new safety standards.

High reliability and safety: The safety control products of HIMA meet the highest level requirements for safety control such as IEC 61508 and DIN V 19250, and have obtained the certification of the highest level AK7/SIL4 from TUV. Adopting a dual 1oo2D structure (i.e., 2oo4D structure), it has a powerful fault-tolerant function. If any component in the system fails, it will not affect the normal operation of the system. At both the central equipment and I/O levels, single or redundant equipment configurations can be provided according to the requirements of security and availability.

Flexible system configuration: The HIMA system can be seamlessly integrated into various automated environments and can use preferred equipment of the same class. For instance, through Ethernet-based protocols such as PROFINET (controller) and PROFIsafe (host), it supports full-loop digitalization for functional safety and offers a variety of options for integration at the field level, including IO, HART, and other general-purpose bus systems and networks. All the equipment in the factory can also be configured from a central point, facilitating the re-designation of equipment and allowing for easy expansion and changes at each stage of the project.

Easy to maintain and manage: With predictive maintenance, detailed diagnostic information, and rapid equipment replacement, maintenance time can be shortened. A unified communication infrastructure helps save engineering time and simplify operations such as processes, procurement, and inventory handling. Xima professionals are also responsible for the engineering, programming and comprehensive integration of automation at all levels, helping users formulate appropriate factory maintenance plans. During operation, users can obtain all transparent information from the site to the enterprise.

Rich industry experience: HIMA's business areas cover process safety, plant machinery safety, public building safety and other fields. More than 40,000 sets of its safety control systems have been put into use, widely distributed in industries such as chemical engineering, petrochemicals, offshore oil platforms, long-distance pipelines, oil and gas stations, metallurgy, building materials, automotive manufacturing, transportation and pharmaceuticals. It has extensive application experience in various fields and can provide the most authoritative safety solutions for users in different industries.

Customized Services: HIMA has a professional team of engineers who can provide customized safety solutions based on the specific needs of customers, helping factories enhance functional safety, information security, and economic benefits.
