(b) File size units classified by memory cards
* 1 : The file size unit of the Flash card applies to the following cases.
•When files are written to the Flash card by selecting [Online]
[Write to PLC (Flash ROM)]
[Write to PLC (Flash ROM)] in GX Developer, (
Section 5.2.7(1)(b))
•When files are written to the Flash card directly using GX Developer without the CPU module
being relayed.
* 2: The Basic model QCPU, High Performance model QCPU, Process CPU, and Universal model
QCPU do not support the use of the Q3MEM-4MBS and Q3MEM-8MBS.
(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 execution program) displayed by GX Developer.
(
3) Allocate memory for online change: 500 steps/2000 byets
