PCD230A 励磁控制系统 ABB 有两个主要的处理器

PCD230A其主要性能如下：

结构紧凑单槽的CPU模块,在CPU模块中有两个主要的处理器。一个是Intel微处理器用于处理一些模拟量或特殊功能控制。另一个是布尔运算协处理器用于执行高速的开关量控制。

一些型号的CPU模块具有浮点运算功能。系统机架采用标准的VMEbus结构。可安装超过300家的第三厂家VME标准模块。系列90-70PLCI/O容量zui大为开关量12288点，模拟量8192点。CPU的内存可从32K字节扩展到6M字节。具有高密度(32点)的AC或DC输入/输出模块。简易的模块夹子，可以防止错误安装I/O模块。具有标准的硬件方式，可响应开关量或模拟量中断输入。可处理64个事故中断和16个时间中断。很方便的系统和模块自诊断功能，且极易排除故障。在CPU模块内，有电池支持的内部日历和时钟。具有Genius分布式I/O模块子系统和Field control系统及VersaMax配置，且可构成双总线的系统冗余配置。对于特殊应用需要可构成完全同步的CPU热备冗余配置。

系统90-70PLC还可以构成用于ESD(紧急停车系统)的ESD双重化和三重化GMR系统配置。

系列90-70 PLC具有功能很强的编程及组态软件，Logicmaster采用结构化的编程方式。除可采用一般的梯形图逻辑编程式外,还可用C,SFC,STATE LOGIC等多种编程能力。

The main properties of PCD230A are as follows:

Compact single-slot CPU module with two main processors in the CPU module. One is the Intel microprocessor used to handle some analog or special function control. The other is a Boolean coprocessor for performing high-speed switching control.

Some models of CPU modules have floating-point arithmetic capabilities. The system rack adopts the standard VMEbus structure. Can install more than 300 third manufacturer VME standard modules. The series 90-70PLCI/O capacity is up to 12288 switching points and 8192 analog points. The CPU's memory can be expanded from 32K bytes to 6M bytes. AC or DC input/output modules with high density (32 points). Simple module clamps to prevent incorrect installation of I/O modules. Has a standard hardware mode, can respond to switching or analog interrupt input. Can handle 64 accident interrupts and 16 time interrupts. Very convenient system and module self-diagnosis function, and easy to troubleshoot. Inside the CPU module, there is a battery-supported internal calendar and clock. It has Genius distributed I/O module subsystem, Field control system and VersaMax configuration, and can form a dual-bus system redundancy configuration. For special applications, CPU hot spare redundancy configuration can be fully synchronized.

System 90-70PLC can also constitute ESD dual and triple GMR system configurations for ESD(Emergency shutdown system).

Series 90-70 PLC has powerful programming and configuration software, Logicmaster adopts structured programming method. In addition to general ladder LOGIC programming, it can also be used C,SFC,STATE LOGIC and other programming capabilities.
