Product Description
2 Product Description
2.1 Product Overview
The CU8871-0000 offers a CFast socket with USB connector in a compact housing for DIN rail mounting.
CFast Flash cards are used in the industrial environment as data memory for process and control data.
The CFast cards are hot-plug capable in the CU8871 and can hence be plugged and unplugged like
removable data storage devices for exchanging data with other PCs during operation.
The USB 3.0 connection offers the highest data transfer rate possible with a CFast card, but the CFast
card adapter can also be connected to PCs with a USB 2.0 interface. Power is also supplied via USB.
Status LEDs indicate whether the CU8871 is connected in addition to indicating data accesses and
providing information on the write protection of the inserted CFast card.
Other outstanding features are:
• user-friendly installation via integrated DIN rail adapter
• no power supply needed – the box is supplied by USB (5V DC)
• USB 3.0 input for compatibility to all USB standards
• standard USB cable for data exchange
• compact industrial design.

Product Description
2.3 Compact-Flash card
The Compact-Flash card (CFast card) is a non-volatile memory media. Data to be retained in the event of a power
failure should be saved on the CFast card. The CFast card operates similar to a hard disk.
Only use CFast cards that are made for industrial use
It is recommended only use CFast cards that are made for industrial use. They
Note
2.3.1 Inserting the CFast Card
The CFast card must be inserted carefully upright with the written side to the left in the CFast slot. The
slot has a protection to ensure the right inserting direction. The card can only be inserted wrong direction
with violence.
possess a higher number of read / write cycles and an enhance temperature range (up
to + 85°C).
A proper operation of the device can only be guaranteed with the use of CFast cards
from Beckhoff Automation GmbH!
As soon as the card is inserted, the LED (P20) lights up green. The red LED (P21) flashes up shortly, too.
2.3.2 Ejecting the CFast Card
