自控模块以及modbusslave模块在服务器IP变化后，计算机特征码会发送变化
rapid scada软件部署在一台支持WiFi以及有线网络的服务器中，在服务器有线网络故障后切换成WiFi，上述2个模块的授权仍能生效吗？modbusslave程序是否能够支持转发数据？

The computer characteristic code of the automatic control module and the modbus – slave module will change after the server IP changes.
The Rapid SCADA software is deployed on a server that supports WiFi and wired network. After the wired network of the server fails and switches to WiFi, will the authorizations of the above two modules still be valid? Can the modbus – slave program support data forwarding?

机器码和mac地址，计算机名称等有关。 多网卡下，用任意网络都可以访问。

你说的网络故障，如果只是网络连接断开，不影响。但是如果是整个网卡都无法识别，可能会导致机器码更改，下次重启后，授权无法生效。

It seems to me that the question here is different.
A server with two provider IP addresses, the primary and backup. Modbus Slave is running on it – how can I access it from the outside when the channel switches to backup and the IP changes? It seems to me that this server needs to be connected to another node via vpn and regardless of the communication channel in the VPN network, it will have the same IP address – here at this address and poll Modbus slave. In this case, the master must also be in this vpn network or have routing to it.

Also, the server running Modbus slave can be a TCP client to another node. This may also allow it to be polled, regardless of what IP it will have.
