Writing Data To The Programmable Controller - Mitsubishi Electric MELSEC iQ-R Series User Manual

5.6

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 redundant system is in 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 settings 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.
( Page 51 Resetting the CPU Module)
• Use the [Select Favorites] button to register frequently used items such as system parameters, CPU
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.
Precautions
Do not write data to both systems during the initial processing (or while the READY LED is on) after the other system is
powered off and on or reset. Writing to the programmable controller may fail due to the operating status mismatch.
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 redundant mode, the
window shown on the left appears. Click the [Yes]
button.
4.
Click the [Yes] button.
5.
When writing the data to the programmable controller is
completed, click the [Close] button.
