The AC800F controller motherboard ABB PM802F/ABB PM803F has 6 slots and 1 power slot. Among them, 2 slots use fast DMA technology to directly communicate with the CPU for high-speed data. These 2 slots achieve control layer information transmission based on standard TCP/IP protocol Ethernet by inserting Ethernet modules. The remaining 4 slots F1… F4 use interrupt mode to exchange data with the CPU and main memory, and each module can generate its own interrupt source, The powerful interrupt controller and advanced multitasking operating system can quickly respond to interrupt information from these four communication modules and quickly exchange data with them. At the same time, through priority control, it can receive real-time error report information from communication modules. The bandwidth of the CPU board data bus is 100MB/s, ensuring that large amounts of information from various communication modules are quickly transmitted to the CPU unit for processing. In order to ensure the maximum accuracy of data, the main memory chip of the AC800F CPU unit has error detection and modification capabilities. It can check for 2-bit errors in 32-bit data words and modify 1-bit errors. The PM803 motherboard increases the storage capacity of the main memory to 16MB, enabling the execution of large control programs on the AC800F controller, but the corresponding programs keep the device updated.

PLC内的I/O模板，除一般的DI/DO、AD/DA模板外，还发展了一系列特殊功能的I/O模板，这为PLC用于各行各业打开了出路，如用于条形码识别的ASCII/BASIC模板，用于反馈控制的PID模板，用于运行控制、机械加工的高速计数模板、单轴位置控制模板、双轴位置控制模板、凸轮定位器模板、射频识别接口模板等，这在以后还会有很大发展。另外在输入、输出的相关元件、强干扰场合的输入、输出电隔离、地隔离等方面也会更加完善。
