USB device
The USB port can also be used to load the user program or update the sys-
tem.
1.6.4.3 Ethernet
Every Ethernet port (ETH0, ETH1, or ETH2) can be used for communication
between the Modular PLCs XControl: XC-104-…, XC-204-…, XC-303-… and
the programming device.
Each of the device's Ethernet ports provides a different transfer rate:
These Ethernet ports are used for programming and debugging, as well as to
update the PLC's operating system.
Recommendation: Use an Ethernet connection when connecting a PC
Please note:
• Every Ethernet interface must have a correct network configuration.
• If a device has multiple Ethernet interfaces, they must use different net-
work addresses, i.e., one of the first three octets must be used to differ-
entiate between them.
CAUTION
When using commercially available peripheral devices with the
USB Host, it is important to keep in mind that their EMC inter-
ference immunity parameters may render them unsuitable for
use in industrial environments.
CAUTION
NON-GALVANICALLY-ISOLATED INTERFACES
The device may be damaged by potential differences.
▶ Do not connect the connector to the device or disconnect it
without first de-energizing the system.
