Device List Setup

The device list menu item enables you to indicate
which registers on the PLC will receive data from the
devices. In this menu, you will enter the device type
and address for each Siemens device connected to

port 2. You will also indicate to which registers on the
PLC you want the DTU3005 to write device data.

Select Device List from the Edit menu to display the
device list screen:

This screen is divided into two parts:

On the left side of the screen is a list of the devices
connected to port 2 (the list is initially empty). Up
to 32 devices can be attached; however, only 17 of
the devices are visible on the screen at one time.
To see all the devices, click on the scroll bar with
the mouse, or use the Up and Down Arrow and
Page Up

The right side of the screen is used to configure
the data register information for the selected
device, as shown in the example screen on the
next page. You can add or delete devices, or
change device configuration by highlighting the
Device Type

using the fields and buttons on the right side of
the screen.
