Memory Dump Function Processing Time - Mitsubishi Electric MELSEC iQ-R-R00CPU User Manual

Memory dump function processing time

This section describes the time (unit: seconds) taken to save all of the data when the memory dump function is in execution.
The following table shows the time taken for data save under the following conditions:
• Scan time = 1.5ms (up to 3ms)
• Internal buffer capacity setting = 256K bytes (by default)
• SD memory card: NZ1MEM-2/4/8/16GBSD used
*1
Number of points
*2
550.4K points
*3
1224K points
*4
5320K points
*5
9416K points
*1 This indicates the total number of points (total number of words) of devices that are set in the device area, file storage area, and refresh
data register area.
*2 This indicates the number of device points (user device: 38.4K points (words), refresh data register: 512K points (words)) with the CPU
parameters set to default values.
*3 Settings for this number of points (with no extended SRAM cassette inserted) are as follows.
 User device: 40K points (words), file register: 160K points (words), and refresh data register: 1024K points (words)
 "Use Common File Register in All Programs" is selected in the file register setting.
*4 Settings for this number of points (with an 8M extended SRAM cassette inserted) are as follows.
 Total number of points (total number of words) of user devices, local devices, and file registers: 4296K points (words), and refresh data
register: 1024K points (words)
 "Use File Register of Each Program" is selected in the file register setting.
 The number of program files is 10.
*5 Settings for this number of points (with a 16M extended SRAM cassette inserted) are as follows.
 Total number of points (total number of words) of user devices, local devices, and file registers: 8392K points (words), and refresh data
register: 1024K points (words)
 "Use File Register of Each Program" is selected in the file register setting.
 The number of program files is 10.
Real-time monitor function processing time
This section shows the minimum value (unit: ms) of monitor interval that allows monitoring under the following conditions
without data loss during execution of the real-time monitor function.
• Scan time = 1.5ms (up to 3ms)
• Data = agrees with the "Number of points of word device" column in the table below (The value of monitor interval does not
change when a local device or label is specified.)
• Timing = Condition specification (step No. specification)
• Internal buffer capacity = 32K bytes (default)
• Fixed scan interrupt timing = generating a fixed scan interrupt on the head step number of the program where step
numbers are specified
• Performance of the system of personal computer = CPU: Intel
