PROFINET commissioning criteria to ensure a reliable operation
The release of the new PROFINET Commissioning Guideline by the PI (PROFIBUS & PROFINET International) stipulates important commissioning criteria. These ensure that the PROFINET network remains stable from the beginning and are summarized below.

PROFINET commissioning criteria to ensure a reliable operation
■ ■In communication hubs with high data flows → network connection to the controller
■ Measurement required prior to each controller having a multi controller application
Net load

Jitter ■ ■an important parameter for long-term trouble-free operation
■ ■Fluctuation in the time intervals of PROFINET packets → long delay, meaning high jitter
■ ■Constantly high jitter is evidence of a changed load ratio, topology changes or device replacement PROFINET-INspektor® NT

Both solutions provide for testing all the required commissioning criteria.
incl. wiring test in PROFINET and shield current measurement.
PROFINET communication monitoring (telegram gap) ■ Each controller has an internal error counter that triggers a fieldbus error when threshold values are exceeded.
■ A higher threshold value increases the fault tolerance if an error occurs, but also extends time until faults are detected.
■ Recommendation is to retain the standard setting 3. If the setting is changed, a check is needed to determine, if the time is sufficiently short.
