MEMORIES AND FILES HANDLED BY CPU MODULE
(2) When High Performance model QCPU, Process CPU, Redundant CPU is
used
When using the program memory, standard RAM, standard ROM or memory card,
calculate the rough size of each file according to Table5.16.
(Continued on next page)
Table5.16 Memory capacity calculation for files (High Performance model QCPU, Process CPU, Redundant CPU)
Function Rough file capacity (unit: byte)
Drive heading 64
Parameter
Default (increases depending on the parameter setting)
Reference
Boot setting 70 + (18 (number of files))
CC-Link IE controller network setting made Max. 7214/module increased
MELSECNET/H setting made Max. 6180/module increased
Ethernet setting made Max. 922/module increased
CC-Link setting made Max. value of the table below increased
(The values of the table below indicate the increment of each module.)
Remote password setting made 64 + 20 + (number of target modules 10),
max. 164 increased
Sequence program
136
*1
+ ((4 (number of steps) + (number of allocate memory for online change)))
Device comment
74 + (sum of comment data sizes of devices)
• Comment data size of one device = 10 + 10250 a + 40 b
• a : Quotient of ((device points)/256)
• b : Remainder of ((device points)/256)
Device initial value
66 + 44 n + 2 (total number of device points set for the device initial value)
• n : Number of set device initial values
User setting area Value set at formatting (0 to 15k)
Multi-block online
program change
Value set at formatting (0/2k/4k)
File register 2 (number of file register points)
