The maximum line length depends on the baud rate used (DIN EN
19245 Part 3).
Baud Rate
187.5 kBit/s
500 kBit/s
1500 kBit/s
3000 to 12000 kBit/s

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.
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:
Color State Function
Green ON Communication Active
