DeviceNet
6.6.6 EDS File
The EDS file ensures that the Poll I/O Connection is automatically
installed between the DeviceNet master and operating device.
6.6.7 Physical Interfacing
Plug-in connectors on the operating device for connection to the
DeviceNet bus.
For the connection to the bus, use twisted pair, shielded cables only.
Terminate both ends of the bus with terminating resistors.
All signal lines in the operating device are bridged from X2.1 to X2.2.
Connect the connecting cables to all pins, including the reserved pins.
This allows continued use of the cables, even if the bus specification is
extended in the future.
