The maximum length allowed for spur lines connected to the bus cable
is 6 meters. The overall length of the bus cable including all spur lines
is not to exceed the maximum length listed in the table below.
The maximum cable length depends on the baud rate and the cable
type used.
7.2.1.3 Termination
Terminate the DeviceNet bus at both ends by terminating resistors
(120 Ohm).
7.2.1.4 Diagnostics
A diagnostic LED is located at the rear of the small operator terminal.
The LED shows the states of the bus system.
Fig. 7-20: Arrangement of the DeviceNet diagnostic LED
The diagnostic LED at the small operator terminal has the following
functions:
Baud rate Cable type Cable length
125 kBit/s 2 x 1.1 mm 500 m
2 x 0.6 mm 100 m
250 kBit/s 2 x 1.1 mm 250 m
2 x 0.6 mm 100 m
500 kBit/s 2 x 1.1 mm 100 m
2 x 0.6 mm 100 m
