Like its predecessor PROFIBUS, PROFINET is a diagnostic-rich protocol allowing your support team to quickly identify the source of device-related problems. This however is of limited use if the underlying performance of your network is poor. PROFINET networks are often seen as the plug and play solution for industrial networks, giving you the impression that successful completion of your application-specific testing is a guarantee that your network is working efficiently and without errors. This is fundamentally wrong and needs to be considered at the design stage as well as the acceptance stage of a project. This presentation will discuss the issues, how to address them and give typical examples of the equipment required.
Profinet is one of “Industrial Ethernet” protocols. It is the most popular automation networking solution currently. PROFINET can be fully operational on a single network cable alongside other Industrial Ethernet’s including EtherNet/IP and Modbus/TCP.

PROFINET is a member of a family providing industrial communications over Ethernet.
PROFINET is:
completely standard Ethernet (IEEE802.3).
High speed, operating at 100Mbit/s or faster over copper or fibre-optic cables,
makes use of existing IT standards. But, is “real-time” and deterministic,
PROFINET is very well thought out to incorporate all the requirements of automation and control systems.
PROFINET is totally compatible with PROFIBUS but is NOT PROFIBUS over Ethernet.
PROFINET wiring is quite different to PROFIBUS
PROFIBUS:
Uses multi-drop segments with many devices on one cable. Segments are separated by repeaters.
Two-core screened twisted pair cable.
Termination is in the hands of the user – many problems arise because of this.
PROFINET :
Multi-drop connection is not used; all cables connect just two devices together. Switches are used for branching to devices.
Four-core screened twisted pair cable.
Termination is provided within every Ethernet device; no longer in the hands of the user – should eliminate termination problems.
PROFINET – Commissioning Guideline
This is one of several free-to-download guidelines documents from PNO (PROFIBUS and PROFINET User Organisation).
It provides guidance on how to verify the installation aspects of the network as well as how to commission the live system.
These tests are additional to the application-specific, System Acceptance Testing that would usually be performed.
Failure to follow these guidelines puts you at risk of having your application tests pass without a detailed knowledge of the underlying performance of your network

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

13. PROFINET – Commissioning Guideline
13
• This is one of several free-to-download guidelines documents
from PNO (PROFIBUS and PROFINET User Organisation).
• It provides guidance on how to verify the installation aspects
of the network as well as how to commission the live system.
• These tests are additional to the application-specific, System
Acceptance Testing that would usually be performed.
Failure to follow these guidelines puts you at risk of having your
application tests pass without a detailed knowledge of the
underlying performance of your network !
14. PROFINET – Installation Acceptance
14
These are associated with the cabling of the installation and include:
• Visual Checking of the cabling.
• Point-to-Point electrical testing of the cabling using a simple line
tester.
• Point-to-point acceptance testing of the cabling using an Ethernet
Function tester.
Installation Acceptance tests should ideally be performed by individuals
who have Certified PROFINET Installer accreditation.
This is a one day course accredited by PI and delivered by organisations
that have PI-certified Training Centre accreditation.
There are two such organisations in the UK.
15. PROFINET – Installation Acceptance – Visual Checks
15
• The guideline lists 23 individual checks that should be
performed on each cable. Examples are
• Cable laid according to plan?
• Maximum length of 100m observed?
• Cable screen earthed at both ends to a previously proven
earthing system.
• Cable separation rules followed?
16. PROFINET – Installation Acceptance – Line Checks
16
The main criteria for the simple electrical
testing of PROFINET cables are:
• There are no short-circuits between any
wires.
• There are no short-circuits between any
wire and the screen
• There are no wire breaks.
• The shield is connected at both ends.
• The wire pairing has been observed
correctly.
17. PROFINET – Installation Acceptance – Function Testing
17
• Simple line testers are designed to test the
electrical aspects of the cable.
• The more advanced function and acceptance
testers establish the ability of that cable to
successfully transmit predefined data packages
as well as determine cable length, attenuation
and cross-talk.
• Such tests are very useful as a baseline in the
event of needing to perform such tests at a
later date.
18. PROFINET – Commissioning
18
These are associated with the operational aspects of the installation and
should only be performed on completion of the Installation Acceptance
tests.
• Checking that the addressing and naming of all IO devices are in
conformance with the design specification.
• Determining other device-related information such as MAC addresses,
Firmware versions etc.
• Establishing that the topology is in conformance with the design
specification.
• Establishing the absence of discarded and error telegrams.
• Establishing operational characteristics – IO Device Cycle time, Net
load, Jitter, Broadcast.
Installation Acceptance tests should ideally be performed by individuals
who have Certified PROFINET Engineer accreditation.
This is a three day course accredited by PI and delivered by
organisations that have PI-certified Training Centre accreditation.
19. PROFINET – IO Device Identification
19
• Every PROFINET device has a world-wide unique MAC address
assigned by the manufacturer.
• The MAC address is unique to that particular device and will
change if the device is replaced with a spare.
• Before a device can take part in communications with an IO
Controller, it must have been configured with a PROFINET Device
Name. This is usually done with the configuration software of the
IO Controller (e.g. Siemens TIA Portal) but can also be done using
readily available PROFINET tools.
• When the IO Controller initialises communication with the IO
Device, it will allocate an IP address to it.
• Every IO device will also have manufacturer-specific hardware
and/or firmware versions.
• Note - All real-time communications takes place using MAC
addresses.
MAC Address: 00: 0E:CF:04:68:7A
Device Name: MySensorName123
IP Address: 192.168.1.23
HW Version: 1.0
FW Version: 1.24
20. PROFINET – Topology
20
Line
Tree
Star
Ring
PROFINET is very flexible when it
comes to laying out the network.
However, each of the four shown
come with advantages and
disadvantages that need to be
considered at the design phase.
It is important o ensure that the
actual topology is in conformance
with that described in the design
specification.
21. PROFINET – Topology – Line Depth
21
• Line depth is the number of forwarding switches between an IO Controller and an IO Device.
• The line depth will affect the cycle time that the device can be polled at.
• The choice of switch (store & forward / cut-through) also affects this (see next slide).
23. PROFINET – Test for “Discarded Packets”
23
• A switch may discard packets due to transmission problems or internal queue overflows at high
network loads.
• This should be evaluated over a period of 60s at high network loads.
• During this period, there should be no discarded packets.
Missing Packets at high Load
24. PROFINET – Test for “Net load”
24
• This is defined as the % of bandwidth used by the real-time communications.
• It should be checked at every IO Controller.
• The ideal value is <20%.
• Values in the range 20% to 50% - further investigation required.
• Values > 50% require actions to reduce the net load
Testing for Net Load
25. PROFINET – Test for “Broadcasts and Multicasts”
25
• Occasionally, broadcast and multicast telegrams will appear on the network.
• These are telegrams that all devices on the network will respond to. Typical examples
include:
• ARP broadcasts – Address Resolution Protocol telegrams are used during entire
scans of the network and initiated by engineering systems, diagnostic tools and IT
systems. Values > 0 and for entire IP ranges should be investigated.
• DCP multicasts – Device & Configuration Protocol telegrams are generated by an IO
Controller on start-up to search for devices with a given device name prior to
allocating an IP address. Values > 10 are considered high should be investigated,
those > 20 are considered too high for trouble-free operation.
• MRP multicasts – Media Redundancy Protocol telegrams are used to determine data
flow direction in ring topologies. Values > 0 should be investigated.
Note – these values can be checked at any point on the network, including a spare port on a
switch.
26. PROFINET – Test for “Jitter”
26
The organisation of PROFINET timing ensures that real-time communication with
a particular device is achieved with a regular update time.
However, it is possible that delays within switches and devices can cause the
transmission time to vary from cycle to cycle.
Such variable delays can give rise to “jitter”.
Jitter is something that should be evaluated.
Update time
Time
Jitter Jitter
27. PROFINET – EMC Criteria
27
• EMC (Electromagnetic Compatibility) and Protective
Earth (PE) issues are acknowledged as being the cause
of a significant number of problems on Fieldbuses and
Industrial networks like PROFIBUS and PROFINET.
• This is because of the ever-increasing frequencies that
such systems operate at.
• Simply ensuring that the cable screen is connected to
earth at both ends serves no purpose if the earth loop
impedance at “typical” frequencies is too high.
• The screen impedance of all PROFINET cables should <
0.6 and the current >0mA AND < 40mA.
• The impedance of the Functional Earth at “typical”
frequencies should be <0.3 .
• Any values outside of this range should be
investigated.

29. PROFINET – Acceptance Specification
29
• This document acts as a formal record of the
