Table 9: Ethernet Interfaces Properties
Two RJ-45 connectors with integrated LEDs are located on the top and on the bottom left-
hand side of the housing. Refer to Chapter
3.4.1.3 for a description of the LEDs' function.
The connection parameters are read based on the MAC address (media access control
address) defined during manufacturing.
CPU and COM have their own MAC addresses. The CPU MAC address is specified on a
label located above the two RJ-45 connectors (1 and 2).
Figure 7: Sample MAC Address Label
The COM MAC address corresponds to the CPU MAC address, except for the last byte
witch is increased by 1.
Example:
CPU MAC address: 00:E0:A1:00:06:C0
COM MAC address: 00:E0:A1:00:06:C1
The controller is equipped with an integrated switch for Ethernet communication. For further
information on the integrated switch and safeethernet, refer to Chapter Communication of
the System Manual for Compact Systems (HI 800 141 E).
