ABB AC800F CPU, ABB PM802F/ABB PM803F

ABB PM802F/ABB PM803F Overview:

ABB PM802F/ABB PM803F on the AC800F controller mainboard has 6 slots and 1 power slot, among which 2 slots adopt fast DMA technology for direct high-speed data communication with the CPU. These 2 slots realize the information transmission of the control layer based on standard TCP/IP Ethernet by inserting Ethernet modules. The remaining 4 slots F1… F4 uses interrupt mode to exchange data with CPU and main memory, each module can generate its own interrupt source, powerful interrupt controller and advanced multi-task operating system can quickly respond to the interrupt information from the 4 communication modules and quickly exchange data with them. At the same time, the error report information of communication modules can be received in real time through the control of priority. The bandwidth of the data bus of the CPU board is 100MB/s, which ensures 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 the AC800F CPU unit has error detection and modification capabilities, which can check the 2-bit error of 32-bit data word and modify the 1-bit error. PM803 motherboard improves the storage capacity of the main memory to 16MB, and implements the large-capacity control program on the AC800F controller. But the corresponding program keeps the device up to date. ABB PM802F/ABB PM803F Features: High efficiency supermax RISC CPU

AC800F

Coprocessor for dedicated system bus and controller redundancy connection communication

ABB PM802F main memory uses static RAM with battery-holding function and starts quickly when the main power supply recovers

ABB PM803F main memory adopts synchronous dynamic Random access memory (SDRAM), which can be quickly started when the main power supply is recovered. It has battery retention function, but the retention time is shorter than ABB PM802F due to its large capacity

The main memory has automatic error checking and modification capability (EDC unit), which can check for 2-bit errors and modify data words with 1-bit errors

Hardware configuration and diagnostic data are stored in 16K EEPROM

The pulse train quickly erases the EPROM for fast ROM operation. This part is mainly used to store the controller curing program, ensuring software upgrade without replacing the EPROM chip

RS232 serial interface for controller diagnostic services and wireless clock signal interface. This interface is a standard 9-pin type D interface on all types of power modules while supporting redundant controller mode operation

Switches for basic operations of the controller are also set on all types of power modules, such as: run/stop work switch, controller reset switch, redundant manual switch

An LED display of controller status is also set on all types of power modules

Slots E1 and E2 are equipped with redundant battery power functions to provide automatic battery energy monitoring/alarm and automatic switch to keep RAM data

CPU mainboard temperature monitoring, periodic temperature measurement

Cumulative controller normal and high temperature running time

All fieldbus modules can be plugged and unplugged while the system is running

Because of the IC interface, F1… F4 slot bus module can automatically identify and reload configuration data to achieve the function of both plug and use

Data error signal recognition and processing from module

Each bus module produces up to four different interrupt sources

Each module reserves the address domain 8MB for memory access and 8MB for I/O access

Operating temperature range 0… In the range of 60 to C, no forced cooling is required. Note that this is the indicator when the controller is packaged as a whole

Internal operating voltage monitoring

A separate watchdog module is used to protect the operating system from deadlocks

The battery keeps the system real time clock

Power failure signal alarm

ABB PM802F CPU mainboard Technical specifications: Weight: 1600g. The CPU mainboard is installed in a rack and does not contain power supplies, modules, or empty panels

Power consumption: depends on CPU load and cycle time: typical: 6W; Max: 7.8W

Voltage monitoring:

If one of the two internal voltages of the CPU board of the controller is lower than the threshold, the CPU board will reset two power supply voltages: 5V+/ — 3%, 3.3V+/ — 3%5V reset threshold: 4.65V3.3V Reset threshold: 3.08V Power failure: When the power module is faulty, a power failure signal will be generated within 20ms. At this time, the power module can ensure the working Tpf time to ensure the normal power switch or emergency shutdown process: Tpf >15 ms

Battery Hold: Lithium battery 3.6V >700mAh, available through E1 or E2 slots, improves hold time when redundantly configured, usually >1.5 years

EDC unit: Provide checksum check function for every 32 bits of data to improve data reliability: modify 1 bit error; Mark a 2-bit error

EPROM: Pulse string to quickly erase EPROM, achieve fast access, in the installation of system software can use special programs programming, no need to update the EPROM: 4MB 32-bit

EEPROM: Configuration data storage, diagnostic data storage, serial 16K EEPROM

Test interface: RS232 serial interface, 9600/19200 baud rate

Temperature monitoring: When the controller works in excess of the specified temperature range, the MTBF time will be shortened. The temperature will be measured periodically and the alarm will be raised when the limit value is exceeded. The alarm signal will be automatically reset when the delay temperature is below

Plugging and unplugging of fieldbus modules: E1… The modules in slot E4 can be inserted and removed when the controller is running

Watchdog: The independent Watchdog module automatically resets the watchdog module if no trigger operation is performed within a specified period of time. This operation prevents deadlocks on the operating system

Real Time clock: The time and date of the real time clock must be set when the control clock is first used, and the clock can be kept running later by the battery
