Whether files are the same between the control system and the standby system is checked.
The following table shows whether or not to perform the check on each file type.

*1 The reserved area for online change and the program restoration information write status are also checked. ( Page 156
Configuration of a program file, Page 741 Program Restoration Information Write Selection)
The SFC information device setting and the operation mode when an active block is activated ("Act at Block Multi-Activated") are also
checked. ( MELSEC iQ-R Programming Manual (Program Design))
*2 Whether a file exists or not is checked. The file contents are not checked.
*3 Files are not checked at the point when an SD memory card is inserted during operation.
*4 The check is performed only for modules on the main base unit. (The system consistency check is not performed for the module
extension parameter for modules on the extension base unit, because the parameter cannot be stored in the CPU module.)
When a mismatch is detected
A stop error occurs in the CPU module of the standby system.
Perform either of the following operations to match the files in the CPU modules of both systems.
• Write files to the CPU modules of both systems.
• Execute the memory copy function to match the files stored in both systems. ( Page 405 Memory Copy from Control
System to Standby System)
