Description
The following modules can be inserted in the
central module subrack:
2 central modules For each central module: 3 F 8621/A coprocessor modules or 5 F 8627X, F 8628X communication modules.
Functional Description of the Safety-Related F 8652X / F 8650X Central Modules
Each central module of type F 8652X or F 8650X is composed of the following function blocks: Two synchronous microprocessors Each microprocessor has its own memory. The memories of one processor contain the program and the data in non-inverted form while the memories of the other processor contain the program and the data in inverted form. Testable hardware comparators for all external accesses of both microprocessors.

If a fault occurs, the watchdog is set to a safe state and the processor status is reported. Flash EPROM as the program memory for operating systems and user programs, suitable for at least 100 000 memory cycles. Data storage in SRAM (static RAM) Multiplexer connection to I/O bus, dual port RAM (DPR) and redundant central module. Buffering of the SRAMs through batteries on the central module 2 RS485 interfaces with galvanic separation and baud rate equal to 57600 bps. The switch or software can be used to set the rate to 9600 bps and 57600 bps (other baud rates are also possible); values set with the software have priority. Diagnostic indicators and 2 LEDs for information from the system, I/O area and user program.
DPR for fast, mutual memory access to the second central module Battery-buffered hardware clock I/O bus logic for connection to I/O modules. Safe watchdog Monitoring of power supply units, testable (5 V system voltage).
