HIMA F8650X Central CPU Module

The central processing module (CPU) of HIMA F8650X is one of the core control units of HIMA's safety instrumented system (Safety Instrumented System, SIS). The F 8650X offers advanced redundancy processing, secure logic computing, and real-time control capabilities, making it suitable for industrial automation scenarios with extremely high requirements for safety integrity levels. This module has undergone strict safety certification and supports multiple industrial communication protocols as well as system integration capabilities.

F8650X processor and memory:
Processor architecture: Dual independent channels 32-bit processor (such as Intel 386EX or ARM Cortex version).
Synchronization mechanism: Dual clock synchronization, supporting redundant logic comparison.
Memory structure:Flash-EPROM: Used for storing operating system and user programs.
                            SRAM: Used for data storage and running memory.

                            Some versions support a arger capacity (the exact capacity depends on the configuration version).

F8650X Communication Interface:
RS-485 serial interface (with electrical isolation)
Ethernet interface (Ethernet network interface)
Support protocols such as Modbus, PROFINET, OPC UA over TLS 1.3, Modbus TCP/IP

HIMA F8650X: Central module Use in the PES H51q-MS, -HS, -HRS, Safety-related, applicable up to SIL 3 according to IEC 61508

Diagnostic display of the central module

–Four-digitt alphanumeric display,

– two LEDs for the general display of errors (CPU for the central modules, IO for the testable input/output modules),

– two toggle switches to request detailed error information,

– push-button ACK resets the error indication; in failure, stop ACK behaves like restarting the system.

For further information on the diagnostic display and lists of error codes, refer to the documentation "Functions of the operational system BS 41q/51q" (also on ELOP II CD).

Notes for start-up and maintenance

– Lifetime of the buffer battery (without voltage feeding): 1000 days at TA = 25 °,C 200 days at TA = 60 °C

– It is recommended to change the buffer battery (CPU in operation) at the latest after 6 years, or with display BATI within three months (Lithium battery, e.g., type CR 2477N, HIMA part no. 44 0000018)

– Check the bus station no and transmission rate at switch S1 for correct settings

– Important: When upgrading an F 8650 to an F 8650X module ,the fan concept also has to be changed!

The F8650X module can be installed via standard 35mm DIN rails or rack slots:
Confirm that the rack contains the designated CPU slots (usually labeled with CPU/central module tags).
2. Gently align the module with the slot, and after confirming that the rear connector is correctly aligned, insert the module into the backplate until the front panel latch catches (hear the "click" sound).
3. The I/O signals of F8650X are usually transmitted through the backplane to other I/O expansion modules. The input (sensor) and output (actuator) signals should be connected with shielded twisted-pair cables and be shielded and grounded at the controller end.
4. The logic program and configuration of F8650X are usually completed using the engineering software provided by HIMA, such as SILworX or Safety Matrix.
5. Download the settings and logic program to the CPU, and complete the safety verification as prompted.
