Ethernet (ENET)

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 2-33shows 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).
