You will find more information about the Ethernet connections in the following Chapter
Ethernet connections X63 / X64 (Page 147).
Ethernet connections X63 / X64
The COM190 communications module has two independent Ethernet
connections X63/X64. The two connections are connected to an internal switch and can
simultaneously use the PROFINET IO and the Modbus TCP protocol. A switch function
enables the connection of additional PROFINET IO or Modbus stations in a daisy-chain
procedure.
The connections support a transmission speed of 100 Mbps. For more information, see
Chapter Technical specifications (Page 377).
MAC addresses
The COM190 communication module has three MAC addresses. These addresses are
divided as follows:
• Two MAC addresses for the Switched Ethernet connections X63/X64
• One MAC address for the COM190 communication module (printed)
