[0043] In an exemplary embodiment, as Figure 1 shown, this embodiment provides a PLC port mapping system, including:
[0044] A PLC body; the PLC body has multiple ports; the multiple ports include spare ports and used ports. When a used port is damaged, the spare port is mapped to the damaged used port;
[0045] A mapping module, which is used to automatically map a spare port to a damaged port when a port damage is detected;
[0046] A configuration software, which is used for users to configure the mapping relationship of the mapping module;
[0047] A saving module, which is used to save the mapping relationship configured by the user.
[0048] In this embodiment, the design of the mapping module includes multiple key components, specifically as follows:
[0049] A status detection unit, the main function of this unit is to monitor the working status of the port in real time to ensure the normal operation of the port and the stability of data transmission;

[0051] A port address configuration unit, the main responsibility of this unit is to set the communication address of the port mapping to ensure that data can be accurately sent to the specified port.
[0052] The configuration software includes:
[0053] A port configuration interface, the main function of this interface is to display the current port status and provide port mapping configuration options for users, so that users can intuitively understand the port status and perform corresponding configurations. Specifically, as Figures 2 - 4 shown, the port configuration interface includes a logic input module, a logic output module, an analog input module, an analog output module, and a control input module;
[0054] As Figure 4 shown, when it is necessary to switch the damaged port, for example, the port at channel 3 fails, then pull down the option and select the port to which it needs to be mapped.
[0055] In addition, the saving module is also an important part of the system, and it includes:
[0056] The power-off protection unit, whose main function is to protect the mapping relationship data from being lost in case of power interruption or accidental power-off, ensuring the integrity and reliability of the system data.
[0057] Among them, the system also includes:
