Interfaces
The maximum line length depends on the baud rate used (DIN EN
19245 Part 3).
7.3.2.3 Termination
Terminate the PROFIBUS at both ends by terminating resistors. If you
are using special PROFIBUS connectors, these resistors are usually
integrated into the connector and can be connected.
7.3.2.4 Diagnostics
A diagnostics LED is located on the rear of the small operator terminal.
The LED shows the states of the bus system.
The diagnostics LED on the small operator terminal has the following
function:
Baud Rate Cable Length
187.5 kBit/s 1000 m (3280.839 feet)
500 kBit/s 400 m (1312.335 feet)
1500 kBit/s 200 m (656.167 feet)
3000 to 12000 kBit/s 100 m (328.083 feet)
