5 Creating Project Files—Modbus Master to Devices

Siemens Energy & Automation, Inc. 41

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

only allocate registers for those containing device

data. (This does not apply to SEAbus devices, for

which the DTU3005 allocates 16 registers regardless if

they are used or not.)

5.8 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 contacts, 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.
