from a NE1A-SCPU01 to a NE1A-SCPU01-V1 or NE1A-SCPU02 in a system
that uses a NE1A-SCPU01, the previous configuration data can be used by
converting it from configura-tion data for the NE1A-SCPU01 to configuration
data for the NE1A-SCPU01-V1 or NE1A-SCPU02.

Use the following procedure to create configuration data for the NE1A­SCPU01-V1 or NE1A-SCPU02 from configuration data for the NE1A­SCPU01.

1. Reading Configuration Data

Use the following procedure to read the configuration data with the Network
Configu-rator (version 1.6).

• Read the saved configuration data.

• Use network uploading to read configuration data from devices on the
network.

The following screen will be displayed when reading has been completed.
