ABB PM802F-Z module controller
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
