Control IPCs APAX System Architecture Introduction Advantech’s Control IPC is a powerful control platform for IoT and other industrial automation applications. Its computing power and different types of standard high speed communication interface make big data processing and decentralized architecture possible. Users can easily add their own vertical application software with the Control IPC and implement the system in automation field sites. To simplify the system configuration, APAX-5000 series provides an easy and flexible way to setup different functions and configurations. There are multiple APAX series system combinations that can be selected to develop reliable control systems as detailed below. Application Ready High Performance Control IPCs Advantech’s APAX-5580 series and APAX-5620 control IPCs benefit from the high throughput, openness, flexibility and connectivity brought by PC-based architectures. Contributed by excellent heat dissipation technology with no hard disks, they deliver great system reliability. Various peripheral interfaces such as LAN, USB, DVI, audio, RS-232, RS-422/485, etc., are provided. These high performance Control IPCs are suitable for many complex control applications. Besides, its powerful integration ability makes it an ideal platform to integrate video, audio, HMI/SCADA software, database, data processing into one single solution.

Depending on customers request , the power supply can be separated to increase the availability. Remote I/O Scalable System For different fieldbus or real-time Ethernet networks, such as Modbus/TCP, Ethernet/ IP, PROFINET, etc., APAX series offers different kinds of couplers for communication. Controllers, HMI, and computers in the same network can access APAX I/O modules through the coupler. Not having to change I/O modules for different fieldbus or real-time Ethernet networks helps ensuring current I/O modules’ investment for future demands. These couplers feature daisy-chain design, making installation easier. Reliable Backup System APAX-5000 series delivers system backup functionality to significantly decrease the risk that the system will fail when the controller crashes. To leverage this, two controllers with the same control program are installed in one system. After both controllers’ backup functions are enabled, APAX-5000 will automatically delegate one controller as the master controller.Themastercontrollerwillrunthecontrolprogramtoexecutethecontrolprocess, while another controller (the backup controller) is put on standby. The master controller periodically sends live messages to the backup controller. If the backup controller does not receive a message from the master controller, it will automatically become the master controller and restart the control process. If the master controller is switched, it means there was an error happening on the previous master controller. Therefore, engineers can repair or change the previous master controller and re-enable it as the backup controller. Then if the new master controller fails, the new backup controller will automatically take over the control once again. This mechanism ensures the control system will continuously run the control process. Chapter 12 Table of Contents Table of Contents
