Interrupt Map VMIVME-7740 BIOS maps IRQ x-rays to appropriate devices according to standard ISA architecture. Refer to Figure E-2 on page * * * 21. This initialization operation cannot be changed; However, the custom application can reroute the interrupt configuration after the BIOS completes the initial configuration cycle. External devices based on PCI bus include two PCI expansion sites, PCI to VME bus bridges and VGA reserved connections. The default BIOS maps these external devices to the PCI interrupt request (PIRQx) line of PIIX4E. The mapping is shown in Figure E-2 on page * * * 21 and defined in Table E-3. The device PCI disconnection (INTA to INTD) existing on each device cannot be modified. The motherboard accepts these PCI device interrupts through the PCI interrupt mapper function. By default, BIOS maps the PCI interrupt request (PIRQx) external device line to an available IRQ (9, 10, 11, 12, 14 or 15) from the PIC interrupt request line.

With the integration and development of IT and OT technology, the industrial Internet of Things has become the trend of the times. The related technologies of PLC communication and the Internet of Things will be popular in the future. Common PLC controller communication includes communication between PLC controllers and communication between PLC controllers and other intelligent devices. With the development of industrial control automation, all PLC controller manufacturers attach great importance to the communication function of PLC controllers and have launched their own network systems. The new PLC controller has a communication interface, which is very convenient for communication. Miniaturization and integration will be higher and higher. With the requirements of the market for miniaturization and integration, PLC technology will be more integrated into industrial, automotive, communications and other products. PLC products are characterized by control and data processing. While meeting the functions, the process requirements are also more detailed. With the development of intelligent factories and the Internet of Things, new requirements have been put forward for the technical development of PLC in the fields of joint control of factory equipment, data interaction between PLC and mainframe and other intelligent products, and big data application. This is a new opportunity and a huge challenge. This requires that PLC products have strong environmental adaptability, stability and reliability, can easily access various networks while maintaining a high cost performance ratio, and give full play to the role of PLC products in data acquisition and data interaction.
