Performing the measurement<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA
A typical Profibus-DPDP-RS485segment consists of:* Strand A * Terminating resistor 1* Strand B* Terminating resistor 2* Shield * DP-Master and DP-Slaves<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA+5 VMasterDrives Gateways Field Device+5 V3902203900 VTerminatingResistorABShield0 V390220390TerminatingResistor

<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDASimple & quick adaptationto the DP segment subject of measurement• <strong>PROFIBUS</strong> address• System Baud rate• Slot time• Number of 12 MBit plugs used• Number of devices connected to the bus
<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDAUseful information for physical measurements• Only active stations (masters) have to be disconnected from the bus,slaves may stay connected.• The physical measurement of the <strong>PROFIBUS</strong> line is only carriedout within electrical segments, without including repeaters.• The minimum length of line to be measured is 10 m. The shorterthe line lengths, the more inexactly the measurement may become.• <strong>NetTEST</strong> <strong>II</strong> is designed for standard <strong>PROFIBUS</strong>-Cable type A(150 Ohm surge impedance, core cross section >0,34 mm²).Different types of cables, e.g. obsolete cable type B(100 Ohm surge impedance) are not to be used and arerecognized as faulty by <strong>NetTEST</strong> <strong>II</strong>.Start
<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA<strong>NetTEST</strong> <strong>II</strong> with DP-Master function for mobilesetting into operation• Setting into operation of DP-Slaves without timeconsumingimplementation of an SPS• Configuration of DP-Slaves via comfortable PC tool onthe basis of GSD file and integrated download function• Comfortable access to the I/O-Data of DP-Slaves viafreely definable tags• Display and Coding of DP-Slave diagnostic data
<strong>NetTEST</strong> <strong>II</strong> – Trouble-free &comfortable<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDAThe COMSO<strong>FT</strong> <strong>PROFIBUS</strong>-Configurator supplies <strong>NetTEST</strong> <strong>II</strong>with the DP-Slave configuration
<strong>NetTEST</strong> <strong>II</strong> – Multi-Talent as DP-Master<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• Changing all DP-Slave parameters• Execution of single <strong>PROFIBUS</strong>-DP services• Simple DP-Slave start-up –not just for <strong>PROFIBUS</strong> experts• Direct access to selective I/O-Data,e.g. digital outputsStart
<strong>NetTEST</strong> <strong>II</strong> with Online Functionup to 12 Mbit/s – another highlight<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• <strong>NetTEST</strong> <strong>II</strong> was enhanced by very powerfulonline measurement functions which even onthe operative Profibus give detailedinformation about existing installationproblems.

Measurements with PLC<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDAThe following measurements can be conducted in online mode:• Baud rate detection• Generate live list• Rotation time• Signal level measurement• Signal level summary list• Event log• Event count• Diagnostic event
Baud rate detection<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• During this Baud rate scan the overallsignal quality at the Profibus ismeasured and a status is indicated.
Generating a Live List<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• <strong>NetTEST</strong> <strong>II</strong> analyses the bus traffic andgenerates a Live List of all active and passivebus subscribers broken down by Masters andSlaves.Current Slave Live ListCurrent Master Live List
Rotation Time<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• <strong>NetTEST</strong> <strong>II</strong> determines the time the DP-Masterneeds in order to poll all configured DP-Slaves.• The minimum and maximum values are storedand indicated.Rotation time is an explicit indicator forperformance problems, e.g. in asporadically disfunctional Profibusnetwork
Level measurement<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• <strong>NetTEST</strong> <strong>II</strong> measures the signal qualityof each DP-Slave and visualises thevalue in a bar graph.Discrepancies of the measuredsignal levels from the allowed rangepoint to specific errors of theProfibus network, e.g. signal levelsabove the allowed maximum aretypical for reflexions in the profibusnetwork.
Signal level sum list<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• In the signal level sum list, the result of thesignal level measurement is indicated in formof a table:- ADD – Participant address- COUNT – Number of measurements (excl.Time-outs)- MIN – Minimum Values- AV – Average Values- MAX – Maximum Values
Event log• <strong>NetTEST</strong> <strong>II</strong> analyses the data traffic between DP-Master and DP-Slaves and triggers uponcommunication status changes. The event log isrepresented in form of a table:- ADD – DP-Slave address- DATA OK – DP-Slave is in status of data exchange- NR – No Response, DP-Slave is not responding- TRY – DP-Slave responds only after multiple retriesby DP Master- CFG – DP-Slave was parameterisedor configured- DIA – Diagnostic messages pendingat DP-Slave<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA
Event count<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• Should a singular DP-Slave showcommunication problems in the event protocol,it can be analysed in detail by the eventcounting.• The event count shows the communicationstatistic for a single DP-Slave in detail. Alsoretries and communication errors are counted.
Diagnostic event<strong>FT</strong> AUTOMAÇÃO INDUSTRIAL LTDA• The diagnostic event is an extended functionof the event counting and serves the detailedanalysis of an event.• <strong>NetTEST</strong> <strong>II</strong> offers the choice between 6 eventsthat may be triggered, e.g. diagnostic data orinput/output data can be analysed.• Should the selected event occur, all relevantdata are displayed along with it.
