AI830 3BSE008518R1 axis positioning module
AI830 3BSE008518R1 axis positioning module is generally divided into read-only memory (ROM)
and random access memory (RAM) two parts. Since the control computer runs a set of fixed programs
in normal operation, in order to run reliably, most of the program curing method is used, not only the system
startup, self-test and basic I/O drivers are written into ROM, but also the control and detection function modules,
all fixed parameters and system communication, system management modules are solidified. In the memory of the
control computer, ROM occupies a large proportion (generally several hundred Kb). Some systems will be the user
configuration of the application program is also solidified in ROM, as long as the system is powered on, the control
station can output and run, more convenient to use, more reliable operation, but modify the configura
tion to be complex

The AI830 3BSE008518R1 axis positioning module provides a space for storing real-time data and intermediate
variables for program operation, and parameters modified by users online (such as set values manual operation values,
PID parameters, alarm set values, etc.) also need to be stored in RAM. At present, some DCS have the function of modifying
the configuration online, but the corresponding configuration application also exists in the RAM side to run. Since the control
station basically does not set disks and tape drives, the above two parts are generally stored in the SRAM with
battery backup, and once the system loses power, the data and programs are not lost for more than a few days,
which is conducive to the analysis of the accident and rapid recovery of operation. The RAM space is generally
hundreds of Kb to several megabytes. In some systems with more than a few cpus, there is also a dual-port
random access memory, which stores process input and output data and set values, PID parameters, etc., the
two cpus can read and write to it respectively, so as to realize the synchronization of running data between the
two cpus, when the two cpus take over each other’s work, it will not produce any disturbance to the production process.
