Access Range; Precautions - Mitsubishi Electric GOT2000 Series User Manual

10.2.2

Access range

■1. Access range with connection types
The following shows a target controller of the backup/restoration execution with each connection type.
(1) PLC CPU, motion controller CPU, CNC, and robot controller
Bus connection, direct CPU connection, serial communication connection
Ethernet connection
(2) Inverter and servo amplifier
The backup/restoration is usable for an inverter or servo amplifier that is connected to the GOT through an RCPU
(master station). The inverter or servo amplifier must be connected to the RCPU on the CC-Link IE Field Network.
(The RCPU must be connected to the GOT by Ethernet.)
If the inverter or servo amplifier is connected to the RCPU on any other network, the backup/restoration is not usable.
■2. With multi-channel function
With the multi-channel function, the backup/restoration is executed per channel.
■3. Backing up/restoring data for multiple CPU system
For the backup, the batch backup for all CPUs or specified backup of CPU No. 1 to 4 can be selected with the utility
setting.
The restoration is executed with specifying CPU No. 1 to 4.
When the backup/restoration is executed with specifying CPU No. 1 to 4, multiple CPUs (CPU No. 1 to 4) can be
specified.
10.2.3

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/restoration function, use characters in the JIS code and ASCII code for file names.
(3) Backing up data stored in file registers
Because backing up data stored in file registers takes a long time, some file register data may have different time
stamps in one backup data. Therefore, synchronism of the data is not assured.
Backing up intelligent function module parameters
(4) 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.
➠
■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.
