|
||
|
||
操作步骤：
|
||
1、新建modbus属性，添加相关lua脚本；
|
||
2、新建modbus特征，添加【tcp-port：0-65535】and【tcp-port not 443】and【modbus属性】；
|
||
3、编辑自定义app，删除旧modbus特征，引用新modbus特征；
|
||
|
||
[~wangjunhao] 补充一下现场细节：
|
||
1、新建 自定义属性截图；
|
||
2、新建 自定义特征截图；
|
||
3、自定义app截图；
|
||
4、lua文件；
|
||
5、其他相关文件**liuxueli** commented on *2023-05-31T18:35:31.673+0800*:

[~yangwei] 现场测试环境测试结果如下：
|
||
1、两次上传完全一致的modbus lua脚本 → sapp重启；
|
||
2、两次上传内容不一致的modbus lua脚本 → sapp重启；
|
||
3、第一次上传modbus lua脚本，第二次上传其他任意lua脚本 → sapp不重启；
|
||
4、两次上传完全一致的其他lua脚本 → sapp不重启；
|
||
5、第一次上传modbusA脚本，删除A，再上传modbusB脚本 → sapp不重启
|
||
|
||
补充：
|
||
2用到的脚本如下
|
||
[^modbus_20230517.lua] [^modbusall(1)(1).lua]
|
||
|

4用到的脚本如下
