27.6 Writing Data to the Programmable Controller
Write the set parameters and created programs to the CPU module.
[Online] [Write to PLC]
Operating procedure
*1 When one of both systems is started up first, the window asking for writing the data to only the connected system appears.
• The same data can be written to both systems when the operation mode is the backup mode. Always write
the same data to both systems to prevent the occurrence of a file mismatch in the system consistency
check. When writing programs, FB files, or global label setting after performing [Convert] or [Rebuild All],
always write them to both systems. Otherwise, a file mismatch will be detected.
• To operate CPU modules, write system parameters, CPU parameters, and program files. To operate I/O
modules and intelligent function modules, write module parameters or module extension parameters.
• When new parameters have been set or the set parameters have been changed, reset the CPU module.
( MELSEC iQ-R CPU Module User's Manual (Startup))

parameters and programs. Select [Setting] [Register Favorites Selection] from the menu on the "Online
Data Operation" window and set the items for the [Select Favorites] button.
1. Select system parameters, CPU parameters, module
parameters, and program files on the "Online Data
Operation" window. When FBs are used, select the
corresponding FB/FUN files.
2. Click the [Execute] button.
3. When the Process CPU is not in the redundant mode,
