Cabling test in PROFINET ■ ■A physical check of each line in the form of a point-to-point connection in PROFINET networks is to be made by a cable tester.

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.

System reserve test of POF cabling ■ Power budget (optical system reserve) = Unit of measure- ment for the light reserve capacity available in the section between transmitter and receiver
■ Influenced by cable length, plug-in connections and the transmitting and receive power of the devices

■ ■Discarded packets: telegrams rejected by the switch caused by e.g. interference, transmission errors or over-flow in queues in switches
■ CRC error detection (error telegrams)
Discarded packets / Error telegrams

Based on the design predefinitions there have to be checked:
■ ■Maximum line depth (number of passing devices in one communication line, e.g. switches or IO devices with integrated switches)
■ ■Node information (firmware and hardware versions, device types, names acc. to naming convention)
Topology test

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

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.

Broadcast and multicast traffic ■ The broadcast and multicast traffic is to be checked.
