　第一期 前言 & 威琅安全控制器产品外观
　　今天，我们就来拆解和评测一款最新的安全控制器——Wieland(威琅)最新开发的samos PRO COMPACT安全控制器，来感悟安全，看看对于机器安全为何非要用安全控制器而不是普通PLC?最新的安全控制器又有哪些技术进展?
　　日益重要的安全控制器
　　进入工业文明后，由机器安全引发的工伤开始成为一个社会问题。随着社会和技术的进步，对于工伤的防范在制度上和技术产品上，都有了一套规范。1992年，欧盟标准委员会(CEN)颁布了EN954，这是一个较低复杂度的安全标准，以规范机器的设计，避免对人身的意外伤害。2011年12月起，EN ISO 13849-1替代了EN954，对于机器安全作出了更加细致的规范。在EN ISO 13849-1中，提出了PL(性能等级)的规范方法，目前的机器安全问题评估，都是按照PL的规范进行。
　　如何设计合适的安全回路，以达到各个PL等级的安全标准，是每个电气工程师在设计一台机器时必须要考虑的首要任务。通常，安全回路由安全传感器元件、安全逻辑元件组成，对于简单的安全功能，电气工程师往往会选择逻辑固定的安全继电器作为逻辑元件。
　　但对于一些大型机械或者危险性较高的机器，会面临一些更加复杂的问题。以注塑机举例，一台大型注塑机，安全门可能有多个，还需要考虑模具间有安全地毯，要控制的电机也有多个，同时还需要控制机械手的运动，机械手工作区还有防护栏等，对于这种需要多个安全监控的应用，安全继电器已经无法满足要求，这时，通常就会用到安全控制器。
　　相比于安全继电器，安全控制器不仅有更多的输入点和输出点，同时还具备可编程功能，可以处理非常复杂的逻辑，并进行评估。
　　看到这里，很多人可能会问，那既然是通过编程来实现复杂的逻辑控制，那为何不能用现在常见的稳定性高、功能强的普通PLC呢?为何一定要用安全控制器呢?
　　今天，我们就来拆解和试用一款最新的安全控制器——Wieland(威琅)最新开发的samos PRO COMPACT安全控制器，来看看对于机器安全，为何非要用安全控制器而不是普通PLC?
　　从外观上看安全控制器的特性
　　我们拿到的这款samos PRO COMPACT控制器有一个主控制器和两个模块，分别是控制器CPU模块SP-C0P2-ENI、数字量扩展模块SP-SDIO和模拟量扩展模块SP-SACR22。
　　我们先来一组的前、后、左、右、上、下视图来对这块安全控制器有一个感性认识。
　从外观上，我们可以看到， samos PRO COMPACT是一款紧凑型的安全控制器，其尺寸大小和普通的中小型PLC相仿，仅有45mm。不过这个控制器的外观主色采用了安全设备常用的黄色，而系统中一些不具备安全功能的普通模块，则是白色的，比如通讯模块和一些普通的DI、DO。所以从控制器颜色上，我们就首先能看出安全控制器和普通PLC的区别，当然除了黄色，有的品牌外观采用的是红色。
