Opionally it is possible to provide 5V/0.5A on Pin 4 or 9.
This 5V power supply is short-circuit-proof.
The configuration can only be factory made.
Cables connected to the programming interface (Ethernet or serial) must be
laid separately from the low-voltage cables.
To ensure disturbance-free operation, it is strongly
recommended to use cables with shield.
5.9 CAN
INTERFACE
The communication interface is defined in accordance with the CiA CAN
Specification V2.0 part B. The fully-integrated CAN unit supports the sending
and receiving of frames with an 11-bit identifier. The type of configuration
selected depends on the software protocol. The baud rate can be selected in
a wide range, and only the standard CiA baud rates are implemented.
