Termination connection for PROFIBUS systems
On installation of a PROFIBUS system, care must be taken to terminate the data lines correctly. The
termination generates a well-defined potential state and avoids the occurrence of disturbances by signal
reflections on the data lines. For this purpose, the data lines must be terminated at both ends by
resistors as shown.
