The AC800F controller board ABB PM802F/ABB PM803F has six slots and one power slot, two of which use fast DMA technology to directly communicate with the CPU for high-speed data. These two slots implement the information transfer of the control layer based on standard TCP/IP protocol Ethernet by inserting Ethernet modules. The remaining four slots F1… F4 use interrupt mode to exchange data with the CPU and main memory. Each module can generate its own interrupt source, The powerful interrupt controller and advanced multitask operating system can quickly respond to the interrupt information from the four communication modules and quickly exchange data with them. At the same time, the priority control can receive the error report information of the communication modules in real time. The bandwidth of the CPU board data bus is 100MB/s, ensuring that the large amount of information data from various communication modules can be quickly transferred to the CPU unit for processing. In order to ensure the maximum accuracy of data, the main memory chip of AC800F CPU unit has the ability of error detection and modification. It can check the 2-bit error of 32-bit data words and modify the 1-bit error. The PM803 motherboard increases the storage capacity of main memory to 16MB, so that large capacity control programs can be executed on the AC800F controller, but the corresponding program keeping device needs to be updated.
ABB PM802F/ABB PM803F Features:
Efficient superscalar RISC CPU
Coprocessor for redundant connection communication of dedicated system bus and controller
ABB PM802F main memory adopts static RAM, with battery holding function, which can be quickly started when the main power supply fails to recover
ABB PM803F main memory uses synchronous dynamic random access memory (SDRAM), which can be quickly started after the main power failure is recovered. It has battery retention function, but because of its large capacity, the retention time is shorter than ABB PM802F
The main memory has the ability of automatic error check and modification (EDC unit), which can check 2-bit errors and modify 1-bit error data words
Hardware configuration and diagnostic data are stored in 16K bit EEPROM
Pulse string fast erasing EPROM is used for fast ROM operation. This part is mainly used to store the solidified program of the controller to ensure that the software upgrade does not require replacing the EPROM chip
RS232 serial interface is used for controller diagnostic service and wireless clock signal interface. This interface is a standard 9-pin D-type interface, which is located on all types of power modules and supports redundant controller mode operation
All types of power modules are also equipped with switches for basic operation of the controller, such as run/stop switch, controller reset switch and redundant manual switch
LED display of controller status is also set on all types of power modules
E1 and E2 slots have redundant battery power supply function to provide automatic monitoring/alarm of battery energy and automatic switching to maintain RAM data
CPU mainboard temperature monitoring, periodic temperature measurement
Cumulative controller normal and high temperature operation time
All fieldbus modules can be plugged and unplugged with power when the system is running
Because IC interface is used, F1… F4 slot bus module can automatically identify and reload configuration data to realize both plug and use function
Identification and processing of data error signals from modules
Each bus module generates up to 4 different interrupt sources
Each module reserves 8MB of address field for memory access 8MB for I/O access
The operating temperature range is 0… 60~C, and no forced cooling is required. Please note that this refers to the indicator when the controller is packaged as a whole
Internal working voltage monitoring
The independent “watchdog” module is used to protect the operating system from deadlocks
Battery holding system real-time clock
Power failure signal alarm
