What is an .ncd file and what information does it store?


An .ncd file is an NI-CAN Database file and it stores configuration information about CAN messages (aka CAN frames) and CAN channels. Each message contains one or more channels and these channels have a number of different properties. An .ncd file stores the message names, channel names, and channel properties.

Additional Information

Note to FP-1300 Users: An .ncd file only stores information about CAN messages and channels. An .ncd file cannot be used to configure an FP-1300. An FP-1300's configuration information is stored on the FP-1300 and is loaded onto the computer when the FP-1300 Configuration Utility is launched. An .ncd file is only part of the FP-1300's configuration and does not contain all the information required to configure an FP-1300.
