4.4 Passthrough Setup—Port 3
Port 3 can be used for passthrough communications
to your Siemens SEAbus devices and protective
relays.
A PC running WinPM, or other supervisory software,
connected to Port 3 of the DTU3005P can communi-
cate to the Siemens devices connected to Port 2.
Any messages received on Port 3 of the DTU are
“passed through” to the devices.
To configure Port 3, select Port 3 (Passthrough)
from the Edit menu. The configuration screen is dis-
played (see Figure 4.7).
