Résumé


PROFINET and German Automobile Industry

AIDA - Automation Initiative of

German Car Manufacturers

► Founded 2003

► Development of mutual positions on automation topics

(e.g. harmonization / standardization of technologies)

► 2004 decision for using PROFINET

► Setting requirements for every PROFINET component

being used in Automotive production

– Integrated safety (PROFIsafe)

– CC B (RT) or CC C (IRT)

– Fast Start-Up (FSU)

– Media redundancy

– PI-Certification

Support of network management services

PROFINET and standard Ethernet through

common port

Connectivity via copper as well as fiber optics

Integrated switch for line and ring topologies

PROFINET at Audi Neckarsulm

Network Composition

► First PROFINET installations proving high speed

communication capabilities and robustness in 2006

(A8 Project)

► 1 GBit/s Uplink from Network Cabinet to Access Switch

► Network structure laid-out for up to 8 cells

► Cells based on PROFINET with some Ethernet

components

► Cu-wiring of Facility and Cell networks with PROFINET

Type B cables only

► Field installations of cells (CC-C / IRT) as redundant

POF-rings

– Max. 40ea subscribers plus max. 10ea on branches

– Exceeding subscribers as extra ring on additional

IRT-switch

► Each cell as own Class C network (256 IP-Addresses)

► One network diagnostics interface TH LINK PROFINET

per cell (own IP-address)

Body Shop Production Planning

► Tool for effective and efficient support of

installation quality assurance,

plant asset management ,

and maintenance across

entire lifecycle of the facility

► Automation network diagnostics must:

cover all subscribers (PROFINET and standard Ethernet)

– summarize from entire network all information about:

– diagnostics,

– system, and

– devices including

– their individual diagnostics history

be suitable to support through facility lifecycle at:

– installation,

– commissioning,

– acceptance, and

– maintenance

offer report functionality incl. comparison with previous status

provide continuous monitoring capabilities

support SNMP (IT acceptance) Photos: Audi AG



Final Assembly

► Tool for effective and efficient support of

network management,

maintenance, and trouble shooting

► PROFINET diagnostics and monitoring tool must:

fit in flow of work

relieve maintenance resources

work independent from brand of network components

offer hot plug-in without PLC project modification

provide little hardware footprint for cabinet installation

not require any additional components, e.g. data base PC

provide functionality offering:

– topology discovery,

– different breakup views,

– inventory information about components

– detection of sporadic failures

About the Solution

Three interlocking Components

► Network monitoring and analyzing software (TH SCOPE)

– Consolidation of data from all TH Links

– Network overview and topology information in different views

– Network statistics and history of network quality

– Status and bandwidth information for network infrastructure

– Inventory list with related network and device details, such as device type,

firmware version and, IP configuration

– Detailed information about communication failures

– Generation of reports respectively acceptance protocols

– Comparison with filed reference measurements (previous status)

– Data export functionality (e.g. Reference Measuring, Inventory List)

– Web Server

– SNMP agent for handing over diagnostics information from automation networks to IT

with central network monitoring

► Network diagnostic hardware interface (TH LINK PROFINET)

– Network access

– Monitoring communication and device status

– Passive “listening” and active communication (PROFINET, Ethernet)

– Data collection for processing through specific diagnostics algorithm

► Training

– 1 day, regularly performed at customer´s site

– Content (Ethernet, PROFINET) and methodology (hands-on) defined jointly with customer

Conclusions

► Ethernet-based industrial communication offers the opportunity for

realizing networks utilizing multiple technologies in parallel

► Existing requirement for dedicated network diagnostics tools

► PROFINET leveraging numerous standard Ethernet technologies

and protocols hence provides the prerequisite condition for a

consistent hence beneficial network diagnostics of real life industrial

Ethernet installations

► PROFINET is providing the functionality for highly effective and

efficient network management and maintenance meeting the

challenging demands of a leading premium car manufacturer
