3.4.6 Communication
The Ethernet interfaces and fieldbus interfaces of the CPU 03 module are used to
communicate with external systems.
The controller communicates with remote I/Os via safeethernet. Up to 128 redundant
safeethernet connections can be configured.
i
When configuring safety-related communication, observe the instructions specified in the
SILworX Communication Manual.

Table 8: Connections for Ethernet Communication
The 4 RJ-45 connectors with integrated LEDs are located on the front plate of the module.
Refer to Chapter
3.4.3.3 for a description of the LEDs' function.
The connection parameters are read based on the MAC address (media access control
address) defined during manufacturing.
The MAC address of the module is specified on the label on the rear side of the printed
circuit board. The first MAC address applies for the COM module on the CPU module, the
second for the switch.
Examples of label: MAC-ADR1: 00.E0.A1.00.0E.04 (COM)
MAC ADR2: 00.E0.A1.00.0E.05 (switch)
