For a description of the meaning of the LEDs, please refer to the section for the state LEDs
Ä Chapter 1.7.1.3.9 “State LEDs” on page 754.
The maximum possible bus length of a CAN network depends on bit rate (transmission rate)
and cable type. The sum of all bus segments must not exceed the maximum bus length
Bit Rate (speed) Bus Length
1 Mbit/s 40 m
800 kbit/s 50 m
500 kbit/s 100 m
250 kbit/s 250 m
125 kbit/s 500 m
62.5 kbit/s 1000 m
20 kbit/s 2500 m
10 kbit/s 5000 m
Connection of the Digital Inputs
The following figure shows the electrical connection of the digital input DI8. Proceed with the
digital inputs DI9 to DI15 in the same way.
