Select the data word (16 bit data) from the list and
press
Enter
. Continue to set the other data words in
the same manner. Many data items consist of two
words (32 bit data). It is important that you configure
both words in order to transmit useful information to the
DTU3005’s registers.
6.
Use these options as follows:
a.
Select
Set Defaults
to copy the default custom
device registers to the list. See
Section 4.7.2
for
instructions on setting custom device registers by
device type.
b.
Select
Clear All
to delete all register names from
the list.
c.
Select
Set as Defaults
to save the current cus-
tom register list as the default custom register list.
This will not change the custom registers of other
devices of the same type. See
Section 4.7.1
for
instructions on setting custom device registers for
a single device.
4.
Select
Save
to save your custom register list and then
Ok
to exit this dialog box. Select
Cancel
to exit this
dialog box without making changes.
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 DTU3005 will then only allo-
cate registers for those containing device data. (This does
not apply to SEAbus devices, for which the DTU3005 allo-
cates 16 registers regardless if they are used or not.)
4.7.2
Configuring Default Custom Device
Registers by Device
If you are configuring custom device registers for more than
one device of a certain type, you may configure the default
custom registers from the Edit Menu
Device Defaults
command. After configuring the default device registers, you
may use them for any or all devices, or further customize
individual registers for any of your devices. SEAbus devices
can have 16 custom registers. VDEW devices may have
between 1 and 64 custom registers.
To configure default custom registers for a particular device
type:
1.
Select
Device Defaults
from the
Edit
menu. A list of
devices appears. If you have configured port 2 for SEA-
bus devices, only SEAbus devices will appear on the
menu. Likewise, if you have configured port 2 for VDEW
devices, only VDEW devices will appear on the menu.
2.
Select the device you wish to configure. The default
custom register configuration menu appears. The first
time you select this command, the first 16 registers (64
for VDEW devices) from the device’s standard data reg-
ister list appear on the default real-time data list. 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 the
entries.
