cat9555每次断电都要设置其输入输出吗

PLC断电重启有哪些注意事项：1、工艺程序已经完成，进入停止李桐唤状态，否则需要人工处理生产线上的产品，2、确保工艺流程机械机构处于安全位置，否则可能产生机轮旦械事故哪凯，3、人员安全，4、机电器件（如电机、伺服、步进系统）先断电，5、断电后需要等一定时间（几分钟）再通电。

当然可以，同时打开多个文件读取或写入都是ok的，无论是FAT文件系统还是UFFS文件系统共，可以写个软件测试一下

稍后我写个软蔽神件测试一下，然后再贴出结果

如果需要代码可以再贴出来

通过侍御取消演示模式能解决该问题，其中的具体步骤如下：

1、直接打开电脑的开始菜单老配岩，找到CATIA软件并选择跳转。

2、这个时候d出新的窗口，需要在工具那里点击选项进入。

3、下一步如果没问题，就继续按照图示取消演示卖升模式。

4、这样一来会正常打开CATPart文件，即可达到目的了。
