6Creating 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.
