1 Introduction
1.4.1PLC to SEAbus
The basic configuration is a PLC attached to port 1 of the DTU3005, and the Siemens ACCESS devices attached to port 2. This is shown below in Figure 1.2. Port 3 can be configured as a passthrough to the SEA- bus devices. This allows a personal computer running Siemens WinPM™ or other supervisory software to connect directly to the SEAbus devices at the same time as the PLC. This is shown in Figure 1.3. An addi- tional DTU3005 device can be attached to port 3. Up to 32 DTU3005 devices can be daisy chained together, each connected to up to 32 Siemens devices. This is shown in Figure 1.4.
