3. Select a data item and press Enter to see a list

of device real time data that can be assigned to

that data word (see Figure 4.11). Select Not

Used if you do not want that data word to be

used. Not all of the entries are visible on the

menu. Use the scroll bar or the Page Up and

Page Down keys to view all of the entries.

Select Clear All to set all data words to “Not

Used.” Select Set to Base to create a new base

default for 16 registers for SEAbus devices (64

for VDEW devices) from the device’s standard

data register list.

4. Select Save to save your configuration or

Revert to restore the last previously saved con-

figuration for that device. When you are finished

configuring the default data registers for that

device, select Ok to close this screen.

To conserve registers when using VDEW devices,

you should set all unused registers to “Not Used”

and place them at the end of the list. The DTU3005P

will then allocate registers for those containing

device data. (This allocation does not apply to SEA-

bus devices, for which the DTU3005P allocates 16

registers regardless if they are used or not.)
