Access Range; Precautions - Mitsubishi Electric GOT SIMPLE GS2110-WTBD User Manual

15.8.3

Access range

(1) Access range with connection types
The following shows a target controller of the backup/restore execution with each connection type.
Computer link connection
Ethernet connection
(2) With multi-channel function
With the multi-channel function, the backup and restoration is executed per channel.
(3) Backing up/restoring data for multiple CPU system
Only batch backup of all controllers is executed.
Backup of only specified ones among the controllers Nos. 1 to 4 is not supported.
15.8.4

Precautions

■1. Precautions for backup
(1) Data that cannot be backed up
The GOT cannot back up device current values and data stored in device memories.
For collecting device current values, use the recipe function.
For how to use the recipe function, refer to the following manual.
➠
For collecting data stored in device memories, use GX Developer.
(2) Names of files to be backed up
When characters other than the characters defined in the shift JIS code and ASCII code are used for file names, the
file names may not be correctly displayed with the data backed up on the GOT.
For using the backup/restore function, use characters in the JIS code and ASCII code for file names.
(3) Backing up intelligent function module parameters
For backing up an intelligent function module parameter (IPARAM.QPA), only the parameters that can be stored in
the PLC CPU are the target parameters.
To store other intelligent function module parameters than those, GX Configurator applied to GX Works2 and the
intelligent function module is required.
For the intelligent function module parameters that can be stored in the PLC CPU, refer to the following.
➠
(4) Compatibility of backup data
(a) The backup data used in GS21 can not be used in GT27, GT25 and GT23.
(b) The backup data used in GT27, GT25 and GT23 can not be used in GS21.
■2. Precautions for restore
(1) Communication status between GOT and target controllers
For restoring data, enable the target controllers of the restoration to communicate with the GOT.
When the target controllers of the restoration cannot communicate with the GOT, the restoration cannot be executed.
(2) STOP status during restoration
CPUs for the programmable controller is in the STOP status with the remote STOP before the restoration.
For the CNC C70, the CNC ladder is in the STOP status.
The CPUs and CNC ladder remain in the STOP status after the restoration is completed.
Restart the controllers.
(3) When restoration is canceled
When the restoration is canceled, all the data are not restored to the controllers and the controllers may not correctly
operate.
When the restoration is canceled, be sure to execute the restoration again.
The CPUs and CNC ladder remain in the STOP status after the restoration is canceled.
Restart the controllers.
(4) System configuration with controllers for restoration
Set the same system configuration with the controllers for the restoration as those for the backup.
Failure to do so disables the GOT to restore data to the controllers.
When the system configuration with the controllers for the restoration is the same as those for the backup, the GOT can
restore data to the controllers even if the connection type and CH No. for the restoration differ from those for the backup.
