Memory Card Backup Functions

The DeviceNet Unit stores the following setup data in the internal non-volatile memory (EEPROM).

•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 CS1 DeviceNet Unit, all this setup data can be backed up to and restored from a Memory Card mounted to the CPU Unit (see note).

Note The data can be backed up to a Memory Card only. It cannot be backed up to a EM file.

If all setup data for a DeviceNet Unit that starts normally is saved on a 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 Configurator can be saved from the computer to the Mem- ory Card and can be restored to the DeviceNet Unit mounted to the CPU Unit. This means that setup data cre- ated using the Configurator (scan lists and other parameters) can be downloaded to DeviceNet Units simply by taking the Memory Card to site.
