6 MEMORIES AND FILES HANDLED BY HIGH PERFORMANCE MODEL QCPU
MELSEC-Q
6.9.3 File capacity
The file size differs with the types of files used. When a program memory, standard
RAM, standard ROM, and memory card are used, calculate the size of a file by
referring to the table 6.7 shown below.
Table 6.7 List of File Capacity

Estimated File Size (in bytes)
64
Default: 564 (increased by the parameter setting)
For Reference:
Boot setting to 70 + (18
(Number of files) )
With the MELSECNET/H setting to maximum 4096 / units increased
Parameter
With Ethernet setting to maximum 922 / units increased
With CC-LINK setting to maximum 251 / units increased
With remote password setting to 64 + 20 + (number of target modules
Sequence program
to 164
136 1+ (4
10), increased to up
((number of steps) + (number of steps secured for write during RUN))
74 + (Total of comment data size of each device)
• Comment data size of a device = 10 + 10250
Device comment
a + 40
b
• a: quotient of (Number of device points) / 256
• b: remainder of (Number of device points) / 256

(Total number of device points specified in the device initial value setting)
• n : specified number of device initial values
When set at the time of formatting (0 to 15k)
When set at the time of formatting (0/1.25k/2.5k)

(Number of file register points)
362 + (20 + 2
of traces) + 12
72 + 54
(Number of word device points) + (Number of bit device pints) / 8 )
(Device range) 2
(Number
(Number of failures stored)
70 + 6 (Type of specified device) + 2
(Total points of T, ST and C) / 16)
( (total number of M and V points) / 16 + (D points) + 18
(number of programs) 1
• Symbols "M, V, D, T, ST, and C" stand for the following devices:
M: internal relay
Local device
V: edge relay
D: data register
T: timer
ST: relative timer
C: counter
1: 136 is the default (increases depending on the parameter setting).
2: Round down the fractional portions of (bit devices)/8, (total number of M and V points)/16, and (total number of T, ST
and C points)/16.
