Optional USB interface
The CP39xx can be extended beyond the basic configuration with an additional USB interface. The following ordering options are available:
- USB (order identifier: C9900-E274)
If you have ordered the device with a Beckhoff mounting arm adapter, the additional USB interface is located on the adapter. On a device without a mounting arm adapter, the interface is located at the side of the connection block. Fig. 16 shows the interface on the mounting arm adapter (A) and on the connection block (B).
The interface is located under a screw cap with IP65 protection class. This is fastened by an interior retaining wire and therefore cannot be lost even after unscrewing. In order to gain access to the interface, unscrew the cap and let it dangle on the retaining wire.
The USB interface is used to connect peripheral devices with a USB connection. It is a USB-A socket. USB specification 2.0 is supported.
