There is a graded range of CPUs from the entry-level CPU right up to the high-performance CPU for configuring the controller. All CPUs control large quantity structures; several CPUs can work together in a multicomputing configuration to boost performance. Thanks to their high processing speed and deterministic response times, the CPUs enable short machine cycle times.
The S7-400 is especially suitable for data-intensive tasks in the process industry. High processing speeds and deterministic response times guarantee short machine cycle times on high-speed machines in the manufacturing industry.The S7-400 is used preferably to coordinate overall plants and to control lower-level systems. This is guaranteed by the high communication power and the integral interfaces.Many of the S7-400 components are also available in a for extreme environmental conditions.
它们用于优化连接工业以太网快速连接电缆到数据终端及网络部件。插头都配有坚固的工业兼容金属外壳,可防止数据通讯过程中的故障4个集成绝缘刺破型触点,可很容易地连接 FC 电缆,防止故障。在剥皮电缆端插入刀形端子(开式铰接)之后,压接并与导线接触由于其结构紧凑,插塞式接头(180°IE FC 接头)可用于带有分立式接口的设备以及带有多接口(排)的设备IE FC RJ45 接头用于连接非交叉 100 Mbit/s 以太网,距离远 100 m,无需使用插接线。 通过交换插头中的发送和接收线对,还可以连接交叉电缆打开外壳,里面有彩色标记,即可很方便地将芯线与刀形端子连接。 通过由透明材料制成的触点盖,用户可以检查是否有接触不良现象。S7-400产品介绍:
