Product overview
C7015 11 Version: 1.0
3.2 Interface description
In the basic configuration, the C7015 includes the following interfaces:
• EtherCAT P (X101)
• Power supply (X102)
• Ethernet RJ45 (X103-X105)
• Mini DisplayPort (X106)
• USB (X107, X108)
3.2.1 EtherCAT P
The Industrial PC has an EtherCAT P interface (X101). EtherCAT P (Et Power) is an extension of
the EtherCAT technology in the area of cabling. Via the connector in IP65/67 design, you can use the four-
wire Ethernet cable (according to IP65) for data and for two galvanically isolated, individually switchable
24 V/3 A supplies. This allows you to cascade several EtherCAT devices. For connection and power supply
of I/O as well as field devices you only need one cable.
A protective cap for the EtherCAT P interface is included in the scope of delivery.

On the housing of the PC there are the three LEDs of the EtherCAT P interface (see Fig. 3). They provide
information about the Link Activity (EC L/A), the system voltage (ECP U
S
) and the peripheral voltage (ECP
