Modicon M258 可编程控制器是一种结构紧凑、高性能和高可扩展性的PLC，它体现了施耐德电气的“灵活设备控制”理念。
此 PLC 为设备生产商 (OEM) 而设计，主要面向如包装、物料传输、仓储、纺织以及木工机械设备等应用，为速度控制、计数、轴控制提供高性能的电气控制解决方案。
在性能方面，Modicon M258可编程控制器拥有双核处理器：
● 内核1 专门用于管理程序任务，并且为应用代码的实时执行提供充足的资源。
● 内核2专门用于执行通信任务，程序执行的性能从此不再受影响。
Modicon M258 的执行速度可以达到22ns每指令,即每毫秒可以执行超过45,000条
布尔指令,最大可管理2400个I/O，64M RAM用于程序和数据存储同时提供128MB闪
存用于应用程序和数据的备份，Modicon M258可编程控制器使您从种种设备限制
的顾虑中从此解脱。
在开发Modicon M258可编程控制器时，充分考虑了为客户节约成本的因素，CPUs的
标准配置包含：
● 42 或66离散量 I/O
● 内置串口和以太网口
● 4路模拟量输入 (TM258 ●●●●4L 型号)
开发和技术
所有其特征表明，Modicon M258 可编程控制器降低了装配、接线、调试和维护成
本。
为此：
● 所有模块都具有可插拔端子。
● 所有电气连接都采用弹簧端子块，可加速接线过程同时避免周期性的重新紧固操作。此外，每个端子都有电压传感装置的测试点。
● Modicon M258 可编程控制器的内置串行连接和以太网口采用45度角倾斜RJ45
连接器，使通信通道的连接更快捷。
连接功能，可以快速明了地连接您的通信通道。
● 各种本体和扩展模块的模块化都经过优化，可有效降低订购和组装配件的
数量，同时由于每个扩展模块包括2至42路通道，可确保您的配置投资是减少的。
● 各种配件的特殊设计可以节省大量的机械组装时间。
软件组态所有 M258 可编程控制器和设备都体现了施耐德电气的“灵活设备控制”理念，其配置和编程功能旨在降低成本和优化设备性能。
SoMachine 软件支持六种 IEC 61131-3 编程语言：
○ IL (指令表)
○ LD (梯形图)
○ SFC (顺序功能块)
○ ST (结构文本)
○ FBD (功能块图)
○ CFC (连续功能图)
另外还支持 PLCopen 功能块，以管理设备的运动控制和轴控制。
与施耐德电气产品相集成通过与其他专门用于设备生产的施耐德电气产品 (例如 ATV 变频器、Lexium 伺服驱动器、TeSys 电机启动器和接触器) 相结合，Modicon M258 可编程控制器成为设备架构中不可或缺的要素之一，这得益于其无可比拟的快速安装能力和易用性。
