HIMA-H51Q-HS-B5233-1-997105233   同步微处理器总线板

【产品详情】

同步微处理器总线板（用于CPU、I/O和接口）的5 V DC输出电压在中央单元上监控，检查欠压和故障。

如果同步微处理器总线板出现故障，操作系统通过系统变量向用户的程序提供此信息。

5 V DC 系统电源发生故障，硬件时钟和中央模块上的 RAM 由中央单元上的锂电池缓冲。

– 两个时钟同步微处理器

– 每个 mikroprocessor 都有自己的内存，一个处理器使用真实数据和程序运行，另一个处理器使用反转数据和程序运行 – 两个微处理器的所有外部访问的可测试硬件比较器，如果发生故障，看门狗将设置为安全状态并宣布处理器的状态

– 操作系统和用户程序的程序存储器的闪存 EPROM，可用于至少 100.000 个写入周期

– sRAM 中的数据存储器 – 多路复用器，用于连接 I/O 总线、DPR 和冗余 CU

– 通过带监控的中央模块和总线板上的电池备份 sRAM 的电池

– 2 个带电流隔离的 RS 485 接口。传。速率：最大 57600 bps。通过开关设置为 9600 bps 和 57600 bps，或者也可以设置其他传输。按软件划分的费率（软件值具有优先权）

– 诊断显示屏和 2 个 LED，用于显示系统、I/O 电平和项目的信息

– 双端口 RAM，用于快速访问第二个中央模块的内存

– 硬件时钟，电池备份

– I/O 总线逻辑和与输入/输出模块的连接

– 故障安全看门狗

– 电源监控，可测试（5 V 系统电压）

– 电池监控

【英文介绍】

The 5 V DC output voltage of the synchronous microprocessor bus board (for CPU, I/O, and interfaces) is monitored on the central unit to check for undervoltage and faults.

If the synchronous microprocessor bus board fails, the operating system provides this information to the user's program through system variables.

The 5 V DC system power supply failed, and the hardware clock and RAM on the central module were buffered by the lithium battery on the central unit.

- Two clock synchronization microprocessors

- Each mikroprocessor has its own memory, one processor runs with real data and programs, the other runs with inverted data and programs - all externally accessible testable hardware comparators for both microprocessors, and if a failure occurs, the watchdog will set to a safe state and announce the status of the processor

A flash EPROM of the program memory of the operating system and user programs, which can be used for at least 100.000 write cycles

- Data memory in sRAM - Multiplexer for connecting I/O bus, DPR, and redundant CU

- Back up the sRAM's battery via the central module with monitoring and the battery on the bus board

- Two RS 485 interfaces with current isolation. Pass. Speed: Maximum 57600 bps. The switch is set to 9600 bps and 57600 bps, or other transmissions can be set. Rates by software (software values have priority)

- Diagnostic display and 2 leds for system, I/O levels and project information

- Dual-port RAM for fast access to the memory of the second central module

- Hardware clock and battery backup

- I/O bus logic and connection to input/output modules

- Fail-safe watchdog

- Power monitoring, testable (5 V system voltage)

- Battery monitoring
