PCIe modules
In addition, you can expand the panel PC with PCIe modules by ordering the device with PCIe module slots:
Table9: CP27xx PCIe module slots
Ordering option Description Device generation
C9900-B518 1 PCIe module slot, integrated in the CP27xx, for
installation of Beckhoff PCIe modules, instead of a
connector bracket for leading out interfaces
CP27xx-0010
CP27xx-0020
The PCIe module is the Beckhoff definition of a small plug-in card format with a PCIe-x1 bus interface. For
ordering options, please contact your Beckhoff Sales department. If you have ordered your device without
PCIe module slots and subsequently want to install PCIe modules, you must first send your device to
Beckhoff Service for the conversion (see chapter 10.1 Service and Support [}48]).
If you have ordered the device without an already installed module, you have to replace the blank cover of
the module slot with the ordered PCIe module on your own. To do this, loosen the two M3x4 screws of the
covers, insert the modules and screw the M3x4 screws back in place.
