6 Creating Project Files—SEAbus
Port Expander
This chapter covers configuration of the DTU3005 as a
SEAbus port expander. Once you have created a SEA-
bus port expander project (see Chapter 3), follow the
directions in this chapter to configure the project file.
Then see Chapter 7 for directions on downloading the
project to the DTU3005.
When configured as a SEAbus port expander, the
DTU3005 allows two computers running supervisory
software, such as WinPM, to connect to the same Sie-
mens SEAbus devices. Up to 32 devices may be
attached to port 2 of the DTU3005 by an RS-485 con-
nection. This configuration is shown below in
Figure 6.1
.

Once you have created or opened the project file,
select Edit from the main menu and the following
menu items appear:
• Port 1 (Passthrough) —allows you to configure the
communications settings for the supervisory
computer connected to port 1.
• Port 2 (SEAbus Devices) —allows you to configure
communications settings for SEAbus devices con-
nected to port 2.
• Port 3 (Passthrough) —allows you to configure the
communications settings for the supervisory
computer connected to port 3.
