Backup Processing Triggered By Turning On Sm1351 - Mitsubishi Electric MELSEC iQ-R-R00CPU User Manual

Backup processing triggered by turning on SM1351

Data in the CPU module is backed up at a desired timing.
Operating procedure
Data in the CPU module is backed up by turning on SM1351.
1.
To set the upper limit value for the number of CPU module backup data, follow the steps below.
• Set SD1353 (Upper limit value for the number of CPU module backup data).
• Set SM960 (Upper limit operation setting flag for the number of CPU module backup data).
• Turn on the bit 5 of SD944 (Backup function setting).
For the upper limit value for the number of CPU module backup data, refer to the following.

2.
Turn on SM1351 (CPU module data backup execution request).
SM1351
OFF
SM1350
OFF
END END END
If the backup processing is completed with an error and SM953 (CPU module data backup error check flag) turns on, check
SD953 (Backup error cause), take actions, and then back up the data again as required.
The execution status of the backup processing can be checked in SD1350 (Number of uncompleted folders/
files of CPU module data backup/restoration) and SD1351 (Progression status of CPU module data backup/
restoration). ( Page 269 Progress of the backup/restoration processing)
