program displays an entry box for the RTS delay time.
Enter the time in milliseconds.
Response Time-Out
The
Response Time-Out
tells the DTU how long to wait
after transmitting a request to the PLC if no response has
been received from the PLC. After this amount of time
passes with no response being received, the DTU will
assume that no response is coming and will retry the
request. Enter the time in milliseconds.
Saving Port 1 Configuration Information
Once you have entered all the configuration information,
select
Save
to save the configuration to the project file.
Then select

Esc
key to close the configura-
tion screen.
If you have changed the configuration and have not saved it
to the project file, you will be prompted to either save or dis-
card the changes. Select
Revert
to return to the last previ-
ously saved configuration without saving any changes.

version of the DTU3005 Editor software was installed as
described in
Chapter 2
.
•
The
SEAbus
protocol (as shown in the example screen
above) indicates connection to Siemens ACCESS com-
municating trip units, relays, power meters and other
devices.
•
The
VDEW
protocol indicates connection to Siemens
protective relays using the VDEW protocol.
Note: Not all Siemens devices are supported. For a list
of supported devices, see
Appendix B
.
