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.)

Device Text Setup (7SJ600 Only)
The Device Text to Values Table menu item is only available
for configuring the 7SJ600 relay. It is used to convert status
codes returned from select parameters in the 7SJ600 relay
(only) to values in a format useful to the system connected
to port 2 of the DTU3005. This affects the status readouts
from the device's binary inputs, signal and trip rated con-
tacts, and the LEDs.
To edit this table, select
Device Text to Values Table
from
the
Edit
menu. This selection is only available when the
device protocol for port 2 is set for “VDEW.”
Once open, 64 conversions can be defined. To define a
conversion, enter the 7SJ600 relay status code in the
Text #
column and enter the corresponding output value desired in
the
Value
column.
