Processor architecture: The H51q series usually has a CPU quadruple structure (QMR), that is, the system's central control unit has four microprocessors, and every two microprocessors are integrated on a CU module, and then two identical CU modules form a redundant central control unit. H51Q-MS may also adopt this architecture.
Safety certification: The H51q series products meet the highest level requirements for safety control such as IEC 61508 and DIN V 19250, and have obtained TÜV's highest level AK7/SIL4 certification. At the same time, they meet the EU's EMC standards, obtain CE certification, and meet the G3 standard. H51Q-MS is likely to have the same or similar safety certification.
Communication interface: Referring to the relevant modules of the H51q series, it may be equipped with 2 RS485 interfaces with galvanic isolation. The transmission rate can be set to 9600bps or 57600bps through the switch, and other transmission rates can also be set through software (software value has higher priority).
Power supply parameters: Some modules of the H51q series will have 24V DC/5V DC power supply modules to generate 5V DC working voltage for central modules and control devices. H51Q-MS may also adopt a similar power supply design and may support power redundancy, equipped with dual power supply modules working in parallel.
Storage capacity: Some central modules of HIMA have flash EPROM for operating system program memory and sRAM for data storage. H51Q-MS may also have a similar configuration. EPROM can be used for at least 100,000 write cycles.
Diagnostic function: The H51q series has self-diagnosis technology, which can diagnose all hardware and software operations of the system within one scan period, with a diagnostic rate of 99.99%. The fault information of CPU and I/O cards can be displayed in the information window of CU and other locations. H51Q-MS may also have similar powerful diagnostic functions.
