描述

3HAC029818-001 DSQC663

 块是存储的基础架构，对块的管理是简单的。从全球第一个磁盘存储技术50年前诞生到现在，块的技术没有发生太大变化。磁盘工业生产遍及全球。最近几年，存储行业兴起存储虚拟化和数据整合的新概念，在这些概念和方案中，数据还是以块的形式通过网络进行读写操作。

    块形式的存储在满足数据可扩展性和数据安全性的增长方面，日益显现出其局限性和不足。国际上主要有两类网络化存储架构，它们是通过命令集来区分的。
    第一类是SAN(StorageAreaNetwork)结构，它采用SCSI块I/O的命令集，通过在磁盘或FC(FiberChannel)级的数据访问提供高性能的随机I/O和数据吞吐率，它具有高带宽、低延迟的优势，在高性能计算中占有一席之地，但是由于SAN系统的价格较高，且可扩展性较差，已不能满足成千上万个CPU规模的系统。第二类是NAS(NetworkAttachedStorage)结构，它采用NFS或CIFS命令集访问数据，以文件为传输协议，通过TCP/IP实现网络化存储，可扩展性好、价格便宜、用户易管理，如目前在集群计算中应用较多的NFS文件系统，但由于NAS的协议开销高、带宽低、延迟大，不利于在高性能集群中应用。
    针对Linux集群对存储系统高性能和数据共享的需求，国际上已开始研究全新的存储架构和新型文件系统，希望能有效结合SAN和NAS系统的优点，支持直接访问磁盘以提高性能，通过共享的文件和元数据以简化管理，目前对象存储系统已成为Linux集群系统高性能存储系统的研究热点，如Panasas公司的ObjectbaseStorageClusterSystem系统和ClusterFileSystems公司的Lustre等。

主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
