ABB PM802F/ABB PM803F Overview:
AC800F controller board ABB PM802F/ABB PM803F has 6 slots and 1 power slot, of which 2 slots use fast DMA technology to directly communicate with the CPU for high-speed data, and these 2 slots are inserted into Ethernet modules to realize the information transmission of the control layer based on standard TCP/IP Ethernet. 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 these four communication modules and quickly exchange data with them. At the same time, through the priority control, the error report information of the communication module can be received in real time. 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 the data, the main memory chip of the AC800F CPU unit has the ability of error detection and modification, which can check the 2-bit error of the 32-bit data word and modify the 1-bit error. The PM803 motherboard increases 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 updated.
ABB PM802F/ABB PM803F Features:
High efficiency superscalar RISC CPU
Coprocessor for dedicated system bus and controller redundancy connection communication
ABB PM802F main memory uses static RAM, with battery holding function to quickly start when the main power failure recovers
The ABB PM803F main memory uses synchronous dynamic random access memory (SDRAM), which can be quickly started when the main power failure is recovered, and has a battery retention function, but because of the larger capacity, the retention time is shorter than the ABB PM802F
The main memory has an 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 bit EEPROM
The pulse train quickly erases the EPROM for fast ROM operation, this part is mainly used to store the controller curing program, ensuring that the software upgrade does not need to replace 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, located 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 to provide automatic battery energy monitoring/alarm and automatic switching to maintain RAM data
CPU mainboard temperature monitoring, periodic temperature measurement
Cumulative controller normal and high temperature operating time
All fieldbus modules can be plugged and unplugged while the system is running
Due to the use of IC interface, F1… The F4 slot bus module can automatically identify and reload configuration data to realize the function of both plug and use
Data error signal recognition and processing from module
Each bus module generates up to four different interrupt sources
Each module reserves an address domain of 8MB for memory access and 8MB for I/O access
Operating temperature range 0… 60~C, no forced cooling is required, please note that this refers to the indicator when the controller is an integral package
Internal operating voltage monitoring
The independent watchdog module is used to protect the operating system from deadlocks
The battery keeps the system real-time clock
Power failure signal alarm
