SD Memory Card Backup Functions

The DeviceNet Unit stores the following setup data in the internal non-volatile memory.
• Master scan lists
• Slave scan lists
• Message monitoring timer lists
• Communications cycle time settings
• Master/Slave functions enabled/disabled settings
Note Backup is possible only when scan lists are enabled.
With the CJ-series DeviceNet Unit, all this setup data can be backed up to and restored from an SD
Memory Card mounted to the CPU Unit.
If all setup data for a DeviceNet Unit that starts normally is saved on an SD Memory Card that data can
be read and used when replacing DeviceNet Units, making the replacement process smooth.
Device parameter files (.dvf files) created using the CX-Integrator can be saved from the computer to
the SD Memory Card and can be restored to the DeviceNet Unit mounted to the CPU Unit. This means
that setup data created using the CX-Integrator (scan lists and other parameters) can be downloaded to
DeviceNet Units simply by taking the SD Memory Card to site.
