1 Introduction
1.1 Product Overview
The Panel-Tec DTU3005 is an intelligent, multiple-
function data transfer unit that enables communica-
tions between Siemens communicating power
meters, trip units, and protective relays, and PLCs or
Modbus networks. The device is designed for the
harsh industrial environment and is suited for use in
switchgear. The device is shown below in Figure 1.1.
The device is powered from an external power supply.
Three ports allow for connection to the Siemens
ACCESS devices and selected protective relays, a PLC
or a Modbus RTU or ASCII master system, and a
passthrough, which allows direct communications
with port 1 or port 2 from port 3. Status lights indicate
proper operation, and DIP switches allow access to
programming and diagnostic modes.
The DTU3005 device supports a wide variety of PLCs
and Siemens ACCESS devices. Appendix A lists the
PLCs and protocols supported by the DTU3005.
Appendix B
lists the supported Siemens ACCESS
devices and protective relays.

1.2 Software Overview
The DTU3005 Editor software is a MS-DOS based pro-
gram for configuring the DTU3005 device. It provides
for uploading and downloading configurations via the
computer’s serial port. You can edit and save configu-
rations in project files on your computer’s hard drive.
Chapters 2
