Network Topology 2: ENET and RS-485 Bus
Up to 30 units may be connected to the RS-485 bus. The first unit
connects to the controller via ENET, and the other units are connected
with the RS-485 bus.
Figure 2-33 shows the system of an XG unit with the ENET option and
several XG units connected via the RS-485 bus. Each power supply must
have its own address, defined from the front panel. Only one IP address is
required for your network (excluding computers) and only one controlling
program is required (one per XG with ENET option as noted in “Network
Topology 1: Simple LAN” on page 2–26).
