6 HIGH PERFORMANCE MODEL QCPU FILES
6.9.3 File size
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.
Space for file storage is available as shown below:
• Program memory, standard ROM: 4096 bytes (1 k steps)
• Memory card: 512 bytes
If a file is transferred from a memory card to a program memory during a boot run, the
size of available memory is changed after the file was transferred.
Table 6.7 List of File Size
Function
Estimated File Size (in bytes)
Drive header
64
Parameter
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
With Ethernet setting to maximum 922 / units increased
With CC-LINK setting to maximum 251 / units increased
Sequence program
136 + (4 (Number of steps) )
Device comment
74 + (Total of comment data size of each device)
• Comment data size of a device = 10 + 10250 a + 40 b
• a: quotient of (Number of device points) / 256
• b: remainder of (Number of device points) / 256
Device init
66 + 44 n + 2 (Total number of device points specified in the device initial value setting)
• n : specified number of device initial values
File register
2 (Number of file register points)
Sampling trace data
362 + (20 + 2 (Number of word device points) + (Number of bit device pints) / 8 ) (Number
of traces) + 12 (Device range) 1
Failure history data
72 + 54 (Number of failures stored)
SFC trace data
Maximum 48 k (in 1 k units)
Local device
70 + 6 (Type of specified device) + 2 ( (total number of M and V points) / 16 + (D points) + 18
(Total points of T, ST and C) / 16)
(number of programs) 1
• Symbols "M, V, D, T, ST, and C" stand for the following devices:
M: internal relay
V: edge relay
D: data register
T: timer
ST: relative timer
C: counter
1: 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.
