CPU板的故障诊断维修

CPU板是整个系统的核心，它包括了PLC、CNC的控制、处理线路。CPU板上主要安装有80186处理器、插补器、EPROM、通信接口、总线等部件。系统软件件固化在EPROM中。PLC程序、NC程序、机床数据可通过两个V.24口用编程或计算机进行编辑、传输；同时，NC程序、机床数据变可通过V.24接口进行输入/输出操作。在系统内部，CPU板通过系统总线与存储板、接口板、视频板、位置控制板进行数据传输，实现对这些部件的控制。

当CPU板故障时，一般有如下现象：

（1）屏幕无任何显示，系统无法启动，CPU板上的报警指示红灯亮；

（2）系统不能通过自检，屏幕有图像显示，但不能进入CNC正常画面；

（3）屏幕有图像显示，能进入CNC画面，但不响应键盘的任何按键；

（4）通信不能进行。

当CPU板故障时，一般情况下只能更换新的CPU备件板。

Cyber security has traditionally been perceived as an IT problem, requiring implementation of good network protocols, operating system and application protocols, firewalls, malware protection, and other solutions designed to guard against network attacks. However, there is not always unilateral agreement on what constitutes the edge. For network providers, the edge is often considered as the router, gateway, PC, tablet, or other high functioning device. In the industrial automation space, it may be the actuator that controls a pump. In today’s changing environment, these edge devices are adapting to include more functionality and higher levels of connectivity. With these changes, the risk assessment of the system changes. Where cyber security might not have been needed previously, these devices may become the weakest link in a system if proper measures aren’t taken to guard against the risks.

Implementing cyber security at the edge gives users more confidence in the data. To reach the highest levels of security, security has to be applied much earlier in the signal chain. Providing confidence that the data has not been manipulated by validating the source provides a higher level of confidence in the decisions being made from that data. ADI is in a unique position to redefine the secure edge by leveraging existing solutions that connect the physical world to the digital world.

When it comes to cyber security, complexity is the enemy. For every 1000 lines of code, there are two to three coding errors, which provide avenues to maliciously exploit a system. Implementing cyber security at the point of lowest complexity provides an environment that gives higher assurance that security has been implemented correctly. Secure operations can take place within security boundaries implemented within the edge devices, pushing the chain of trust closer to the real world. In highly complex networks, organizations and individuals must continually update applications and configurations to protect against the latest threats. At the device level, one can limit the secure operations to a footprint that becomes much more manageable throughout the life cycle of the product.
