Execution Data Backup Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

9.3
When the buffer memory data of Motion module is rewritten from the CPU module, "the data backed up in the flash ROM/
internal memory (nonvolatile)" of Motion module may differ from "the execution data being used for control (buffer memory
data)". In this case, the execution data will be lost when the power supply of CPU module is turned OFF.
The "execution data backup function" is used to back up the execution data by writing to the flash ROM/internal memory
(nonvolatile). The data backed up will be written to the buffer memory when the power is turned ON next time.
When the Motion module is replaced, all the data in the Motion module including absolute position data can be
backed up (read to) in the personal computer and restored to (written to) the Motion module again by using
the backup/restore function of an engineering tool. Refer to "Help" in the "Simple Motion Module Setting
Function" of the engineering tool for details.
Execution data backup means
• The backup is executed with a program.
• The data is written to the flash ROM by an engineering tool.
Refer to "Help" in the "Simple Motion Module Setting Function" for the flash ROM write method by an engineering tool.
Control details
• The following shows the data that can be written to the flash ROM/internal memory (nonvolatile) using the "execution data
backup function".
Target area
Parameters
Mark detection
Synchronous control parameters
Positioning data
Block start data
• The module parameters are stored in the CPU module. Therefore, these parameters cannot be backed up in the flash ROM
in the Motion module.
• The cam data (cam storage area) is separately saved in the flash ROM/internal memory (nonvolatile). Therefore, it is not a
target of the backup function.
