*1 The value will be adjusted by the system so that the total number of bytes of PLC parameters and network parameters
becomes multiple of four.
*2 The value will be adjusted by the system so that the total number of bytes becomes multiple of four.
*3 These are default values. (Values differ depending on the parameter setting).
*4 After the decimal point of a value obtained by a division part in the formula is rounded up.
*5 For the Q02UCPU, Q03UDCPU, Q04UDHCPU, or Q06UDHCPU whose serial number (first five digits) is "10011" or
earlier, apply the number of execution programs.
Remark
For a calculation example of memory capacity, refer to Page 51, Section 2.1.3 (4) (c).

• N: Number of target drives
• M: Number of target files
• L: Total size of file names of target files (including punctuation mark (.) and extension)
64 + (6+ (a × 34)) + (6 + (a × (336 + (12 × b) + (12 × c))) + (6 + (d × 198)) + 22 + 5440 + (6 + e ×
6418))
• a: Sampling trace registration status
• b: Number of word device points of sampling trace information
• c: Number of bit device points of sampling trace information
• d: Data logging registration status
• e: Module error collection setting status
• For the status of a, d, and e, put "1" when they are registered/set and put "0" when they are not
registered/set to obtain the above calculation formula.
64 + 2 + 4 + 72 + (N × 8) + 11328 + ((a + (b  16) + (c × 2  16)) × 2)
• N: Number of target devices (for the timer, retentive timer, and counter, the contact and coil are
counted as one device.
• a: Number of word device points
• b: Number of bit device points (except for the timer, retentive timer, and counter)
• c: Number of bit device points (the timer, retentive timer, and counter)
The file size depends on the parameter setting. (1K to 1024K bytes)
