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.
PM802F
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
Technical indicators of ABB PM802F CPU motherboard:
Weight: 1600g, CPU motherboard is installed in the rack, excluding power supply, modules and empty panel
Power consumption: depends on CPU load and cycle time: typical: 6W; Maximum: 7.8W
Voltage monitoring:
If one of the two internal voltages of the controller CPU board is lower than the threshold value, the CPU board will reset
Two power supply voltage standards: 5V+／ – 3%, 3.3V+／ – 3%
5V reset threshold: 4.65V
3.3V reset threshold: 3.08V
Power failure: when the power module fails, a power failure signal will be generated within 20ms. At this time, the power module ensures the working Tpf time, power switching or normal emergency shutdown processing in the process: Tpf>15ms
RAM: 32 bits, providing battery holding function through E1 and E2 slots 4MB static RAM (SRAM)
Battery retention: lithium battery 3.6V>700mAh, which is provided through E1 or E2 slot. The retention time can be improved in redundant configuration, usually>1.5 years
EDC unit: every 32-bit data provides checksum check function to improve the reliability of data: modify 1-bit error; Mark 2 bit error
EPROM: pulse string quickly erases EPROM to achieve fast access. When installing system software, special programs can be used to program without updating EPROM: 4MB 32 bits
EEPROM: configuration data storage, diagnostic data storage, serial 16K bit EEPROM
Diagnostic interface: RS232 serial interface, 9600 ／ 19200 baud rate
Temperature monitoring: when the controller works beyond the specified temperature range, the MTBF time will be shortened. The temperature will be measured periodically and alarm will be given when the limit value is exceeded. The alarm signal will be reset automatically when it is lower than the delay temperature. The operation time at normal temperature and at high temperature will be accumulated independently
Plugging and unplugging of fieldbus modules: modules in E1… E4 slots can be plugged and unplugged when the controller is running
Watchdog: The independent Watchdog module will automatically reset the module when no trigger operation occurs at the specified time, which will avoid the deadlock of the operating system
Real time clock: The time and date of the real time clock must be set when the control crime is used for the first time. Later, the clock can be kept running by the battery
