F-5-2-2 Relation between FDT Project and Device
Maintenance Info
TIP
The information in this chapter is useful when you configure the advanced settings to create a FDT Project.
The following describes the differences between the device DTM data in the FDT Project and
the DTM data in the device maintenance information in the database, and how to assign the
information.
Differences
• A FDT Project stores the Device DTM data, Comm DTM data, and Gateway DTM data.
Also, device maintenance information stores only the Device DTM data.
• A FDT Project stores one set of DTM data for the device.
Also, device maintenance information can store up to five sets of device DATM data.
Assigning
• You can assign the device maintenance information to the device DTM in the FDT Project.
The device DTM data in the FDT Project and in the device maintenance information are
saved in different areas. Therefore, although the FDT Project is saved, the device DTM data
in the device maintenance information is not updated.
The device DTM data can be transferred between the FDT Project and device maintenance
information. For example, when the device DTM is selected in DTM Works and saved to the
database with Save to Database, the device DTM data in the FDT Project is saved to the
device maintenance information.
• You cannot assign different device DTMs in the FDT Project to the same device
maintenance information.
• The FDT Project is deleted, but the assigned device maintenance information is not deleted.
The device DTM is deleted in DTM Works, but the assigned device maintenance
information is not deleted.
In both cases, only the relevant FDT Project item in “Device Info - Communication Path” for
Device Maintenance Info is deleted.
• Although the device maintenance information is deleted, the assigned FDT Project is not
deleted.
When DTM Works is running in the UDC mode, the device maintenance information to
which the FDT Project is assigned cannot be deleted, and also the device information
cannot be changed.
