DSPC-150 ABB模块

DSPC-150 ABB模块

DSPC-150特点：

高效超标量RISC CPU

专用系统总线及控制器冗余连接通信的协处理器

DSPC-150主存储器采用静态RAM，具备电池保持功能当主电源故障恢复

DSPC-150主存储器器采用同步动态随机存储器(SDRAM)，当主电源故障恢复后可以快速启动，具备电池保持功能但由于容量较大，保持时间比ABB 

主存储器具有自动错误检查及修改能力(EDC单元)，可以检查2位错误及修改1位错误的数据字

脉冲串快速擦除EPROM，用于快速ROM操作，这部分主要用于存储控制器固化程序，保证软件升级无需更换EPROM芯片

RS232串行接口，用于控制器诊测服务和无线时钟信号接口，该接口为标准9针D型接口，位于所有类型的电源模件上，同时支持冗余控制器模式的操作

所有类型的电源模件上还设置控制器基本操作的开关，如：运行/停止工作开关，控制器复位开关，冗余手动切换开关

DSPC-150 Features:

High efficiency superscalar RISC CPU

Coprocessor for dedicated system bus and controller redundancy connection communication

The DSPC-150 main memory uses static RAM with battery holding function when the main power supply fails to recover

The DSPC-150 main memory uses synchronous dynamic random access memory (SDRAM), which can be quickly started when the main power failure is recovered, and has a battery retention function, but because of the larger capacity, the retention time is higher than that of the ABB

The main memory has an automatic error checking and modification capability (EDC unit), which can check for 2-bit errors and modify data words with 1-bit errors

The pulse train quickly erases the EPROM for fast ROM operation, this part is mainly used to store the controller curing program, ensuring that the software upgrade does not need to replace the EPROM chip

RS232 serial interface for controller diagnostic services and wireless clock signal interface, this interface is a standard 9-pin type D interface, located on all types of power modules, while supporting redundant controller mode operation

Switches for basic operations of the controller are also set on all types of power modules, such as: run/stop work switch, controller reset switch, redundant manual switch
