When The Module-Specific Backup Parameter Is Not Used - Mitsubishi Electric MELSEC iQ-R User Manual

Reading of module-specific backup parameters
To read a module-specific backup parameter and restore hardware logic, set "Hardware logic control auto restoration
executed/unexecuted" of the module parameter to "Enable" in advance.

■Read timing
Module-specific backup parameters are read when a new module is mounted and recognized after the online module change.
When the programmable controller is powered off and the module is replaced with a new one, module-specific backup
parameters are not read.
■Precautions
When the module-specific backup parameter for the target slot does not exist in an SD memory card or the data memory of
the control CPU, the subsequent restoration of the hardware logic is not performed. If the hardware logic cannot be restored
even though the module-specific backup parameter exists, a module-specific backup parameter restore error (error code:
17E0H) occurs.
Restoration of the hardware logic
When reading module-specific backup parameters is completed with no errors, the hardware logic is converted (restored) into
the hardware logic for the new module and stored in the flash ROM.
Restrictions on the module-specific backup parameter
Hardware logic cannot be backed up or restored with a module-specific backup parameter in the following cases.
• When the control CPU is not the process CPU
• When the programmable controller is powered off and the flexible high-speed I/O control module is replaced with a new one
• When "Hardware logic control auto restoration executed/unexecuted" of the module parameter is set to "Disable"
In any of the cases above, back up or restore the hardware logic by the following method.

When the module-specific backup parameter is not used

Back up or restore the hardware logic with the configuration tool.
• Save the hardware logic for a backup as a project file. ( Page 66 Project Management)
• Write the backed up hardware logic to the module for restoration. ( Page 87 Writing data to the module)
