5.3.3  File size
The size of a file used for the CPU module depends on the file type.
When a file is written to the memory area, the unit of the stored file depends on the CPU module and memory area to 
be written. (  Section 5.3.4)
When using the program memory, standard RAM, standard ROM, or memory card, calculate the rough size of each file 
with reference to Table5.8.

•  With CC-Link IE controller network setting 
• 72 + (total parameter sizes of each module) + (size of the routing setting) + (size of the data link transfer 
setting)
• Parameter size of each module: Up to 10368 (when only LB/LW(1) is set, 1826 + 16 (number of 
refresh transfer points))
• Routing setting size: 6 + 8 (number of routing settings)
• Size of data link transfer setting: 6 + 12 (number of transfer settings) + 86 (number of modules)
• With the MELSECNET/H setting   Increase up to 6180/module
• With the Ethernet setting   Increase up to 922/module
• With the CC-Link setting   Increase up to the values in the following table (The values indicate an 
increment of each module).
• With the remote password setting  92 + (number of target modules 10), increase up to 172/module

+ (4 ((number of steps) + (number of steps of reserved area for online change))
Device comment
74 + 8 + (total comment data size of each device)
Comment data size per device = 10 + 10250 a + 40 b
• a: Quotient of ((number of device points)/256)
• b: remainder of ((number of device points/256)
Initial device value
66 + 44 n + 2 (total number of device points set to the initial device value) + 8
n: number of settings of the initial device value
