A
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 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)
*1
• 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)
*2
• 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
Core

i3-2100 CPU (3.10GHz), Memory: 2GB, OS:
Windows
7 Professional SP1 32 bits
*1 The scan time during non-execution of the real-time monitor function shall be an average of 1.0ms.
*2 Program name: Arbitrary, Step No.: Head step of the program, Execution condition: Set to Always
