Parameters
(b) File size units classified by memory cards
Note5.7
Note7
* 1 : The file size unit of the Flash card applies to the following cases.
•When files are written to the Flash card using [Write the program memory to ROM...] (
Section 5.2.6(1)(b)) on GX Developer.
•When files are written to the Flash card using GX Developer without the CPU module being
relayed.
(2) Memory capacity calculation example
The following indicates an example of calculating the memory capacity when the
parameter and sequence program files are written to the program memory.
(a) Conditions
1) Write target CPU module: Q25HCPU
2) Written files
* 1 : Refer to Section 5.4.3 for the file capacity.
* 2 : Indicates the program capacity (file header + execution program) displayed by GX Developer.
(
Section 5.3)
3) Allocate memory for online program change: 500 steps/2000 byets
