Introduction 3 Introduction With the PROFIBUS NetTEST II you have acquired a highquality tool for the examination of RS485-based PROFIBUS segments. KUNBUS’ aim is to provide its users with a valuable tool for an easy check, without extensive test methods of the correct cabling of their PROFIBUS net and to document this. Furthermore, the search for errors in already installed PROFIBUS systems shall be as easy as possible.
Introduction Apart from these basic functions the following options are available for NetTEST II: DP Master Option With the DP Master Option the set into operation of DP Slaves is possible without the PLC. The DP Slaves can be configured with the KUNBUS PROFIBUS configuration tool based on the DP Slaves appropriate GSD file. Online Function This function performs a detailed analysis of the telegram traffic and the physical state of the PROFIBUS line.
Line Tests 4 Line Tests 4.1 Line Measurement Generally, measurements regarding line physics can only be made from one end of the PROFIBUS line. If you try to measure from any other place within the segment, you will obtain faulty results. Furthermore please make sure that during measurements no Master is polling the bus or is sending tokens. Pure PROFIBUS DP Slave devices as well as e.g. repeaters and optical couplers must not be disconnected from the bus.
Line Tests 4.2 Livelist, SlaveDiag, and Level Detection To make detections as easy as possible, the generating of the livelist, the Slave diagnosis and Slave related transmission level detection should be effected as well from the bus end. However, you can also make these from any other available measuring point within one segment. Here, please observe that the function of the livelist and of the SlaveDiag also work via a repeater, segment coupler or optical coupler.
NetTEST II Menu Guide 5 NetTEST II Menu Guide 5.1 Start-Up / Setting in Operation Check the completeness of the scope of delivery and charge batteries before initial operation. Remove the battery by gently pressing the locking and at the same time pulling down the battery placed at the rear lower side of the NetTEST II. Now place the battery into the charging holder, and check the loading procedure by means of the LED in the battery charger.
NetTEST II Menu Guide 5.2 Main Menu The main menu automatically appears on the display after having started the NetTEST II. Figure 3: Screen ‘Main menu’ The main menu comprises the following submenus: Line Test Test without PLC Stepwise check of cabling and test of DP Slaves, without protocol generation. PROFIBUS Master mode (optional) Set into operation of DP Slaves without PLC.
NetTEST II Menu Guide 5.2.1 Test without PLC The menu Test without PLC serves for stepwise physical analysis of lines. This means that the test can be executed as often as desired. Some tests are based on the reference data of the preceding test, so that this one must be run beforehand. The individual items are interlocked, so that wrong operation is impossible. For test runs under this menu, no protocol is made out.
NetTEST II Menu Guide 5.2.1.1 Segment list Figure 5: Screen ‘Segment list’ Under Segment list, segment-specific data are stored serving as basis for the following measurements. The data are stored in the data base for line segments under the assigned segment name. From there, they can be used as basis for both individual tests and the creation of test protocols. Indications must be made as to the points listed below: Name of line segment (max. 30 characters) PROFIBUS baud rate (9.
NetTEST II Menu Guide The PROFIBUS baud rate, address and slot time are necessary for the parameterization of the installed PROFIBUS Master. With these settings, the tests Generate livelist, Slave ident number, as well as Slave signal quality are executed. Moreover, indications regarding number of: Connectors (only number of 12 Mbit/s plugs!) Devices (all devices with PROFIBUS plug, or connected cable) Connected devices and 12 Mbit/s PROFIBUS plugs considerable change by their inductivity resp.
NetTEST II Menu Guide 5.2.1.2 Test with no terminators At the beginning of each test, the Test with no term. must be carried out. For this, the NetTEST II must be connected to one end of the PROFIBUS segment. Now the user makes sure that all bus termination resistors (terminators) in the bus segment are switched off resp. removed. Furthermore, no Master may send data via the bus. Then the Test with no term. can be carried out.
NetTEST II Menu Guide Figure 7: Screen ‘Test with no term’ The Test with no term. lasts for a few seconds. The duration depends on the cable length. To show the user that the system is still working, a star bar appears on the lower left hand side of the display as progress indication. Terminate the test with . Upon conclusion the result will be displayed. Attention: If you quit the test with , the Test with 1 term. cannot be executed any more, as the just scanned data were deleted.
NetTEST II Menu Guide "Error: A<->B Short circuit or unpowered termination": There is a low ohmic resistance between the signal wires, which might be caused for example by a bus termination without power supply. "Error: A<->B Irregularity, wrong termination or illegal termination ": There is an unacceptable ohmic resistance between the signal wires that stands in no relation to the magnitude of a bus termination either with or without power supply.
NetTEST II Menu Guide With each of these error messages there may be an indication of a distance. Some errors (e.g. invalid termination) do not give conclusive information about the distance. Moreover, all error messages may also include the indication "uncertain error". This may be indicated, if the cause of the error could be detected only roughly, thus permitting only an error estimation.
NetTEST II Menu Guide 5.2.1.3 Test with 1 terminator Prior to the Test with 1 term., in any case the Test with no term. must be completed. If this was not made, the user is being informed about this and can immediately make up for this test. For the Test with 1 term., the terminator at the bus end opposite to the NetTEST II must be switched on and set under current. With a DP Slave unit or another passive bus participant, the plug can be connected directly, the terminator added and the unit switched on.
NetTEST II Menu Guide In case of errors, the following error messages may be displayed: "Error: no termination or switch defect": No valid termination could be detected. "Error: Your terminator is not at the far end of the segment !": Contrary to the instruction the terminator was switched at the near segment end. "Error: A<->B twisted": Mix up of signal lines. "Error: A<->shield / B<->shield short circuit ": There is a low ohmic resistance in the cable between signal wire and shield.
NetTEST II Menu Guide 5.2.1.4 Test with 2 terminators Following the Test with 1 term., the Test with 2 term. is started. Here it is checked if the bus terminator at the line end of the NetTEST II was switched on additionally. For this test, the terminator must also be supplied with power. This can easily be done from the last unit in the segment. If this should be a Master which cannot be made passive, the data line has again to be disconnected from the segment via a bus disconnector.
NetTEST II Menu Guide 5.2.1.5 Generate livelist Figure 11: Screen ‘Generate livelist’ In the menu Generate livelist, NetTEST II scans all possible bus addresses from 0....126 for PROFIBUS DP Slave participants. For this, a FDL request is effected several times on each address. If a device answers with OK, its bus address appears on the display. The unit counter is incremented by one. To ensure that also extremely slow units are recognized, the test takes approx. 30 seconds.
NetTEST II Menu Guide 5.2.1.6 Slave ident number Figure 12: Screen ‘Slave ident number’ Via the Slave ident number menu, the Ids for a better assignment of the DP Slave addresses to the unit type can be indicated. Here, a Slave_Diag_Request is executed on the respective device, and this returns in its answer the ident number. This will then be indicated behind the Slave address.
NetTEST II Menu Guide 5.2.1.7 Slave signal quality Figure 13: Screen ‘Slave signal quality’ With the Slave signal quality, the signal level of the addressed DP Slave is measured. This should be with an impeccable unit and correctly terminated bus and a cable length of 1 m from the measuring point to the Slave at approx. 6.3 Volt. Per 100 m more cable between NetTEST II and the device to be scanned, the level reduces by approx. 0.2 Volt. U < 2.5 V: Weak level or no longer detectable. 2.5 - 7.
NetTEST II Menu Guide 5.2.1.8 Baud rate detection Figure 14: Screen ‘Baud rate detection’ With the menu point Baud rate detection a running bus with active Master is monitored and the current baud rate is indicated. During this baud rate scan, the general signal level at the bus is being measured analogous to Slave signal quality (see chapter 5.2.1.7).
NetTEST II Menu Guide 5.2.2 Test protocol Figure 15: Screen ‘Test protocol’ Test protocol serves for creating measuring protocols needed for documentation purposes. In addition to the test data, the user has the possibility to define plant-specific data like plant name, line segment name, customer data for the test protocol. 5.2.2.1 Create new protocol In the menu Create new protocol, all steps necessary for the test protocol are executed successively.
NetTEST II Menu Guide 5.2.2.1.1 Test without PLC Contrary to individual measurements, the test order instructed by the NetTEST II must be considered. The cable tester always instructs the user how to perform the next test. If a test fails it can be repeated as long as the problem is fixed. The failed test is only stored in the test protocol if the protocol compilation is canceled at this point. By means of the key the single test is confirmed and the protocol compilation continues.
NetTEST II Menu Guide 5.2.2.2 Delete With this menu you can delete existing test protocols from the database. This should only be done if the corresponding protocol was sent to a PC via a serial interface, or if the protocol is no longer needed. 5.2.2.3 Display Stored test protocols cannot only be displayed on the PC, but also be displayed again with this function. Here, the display is analogous to the display during measurement. To go through the individual screens, please use the key.
NetTEST II Menu Guide 5.2.2.5 Test company In this menu you can enter your company name. The data entered are issued in the test protocol. Figure 18: Screen ‘Test Company’ 5.2.2.6 User name list Here, the names of all users can be stored in a data base with 10 memory locations. This saves time in case of multiple test for a renewed indication in the test protocol. At the corresponding place, the user name can be selected by simply using the keys when issuing a test protocol.
NetTEST II Menu Guide 5.2.2.7 Customer list The entry of customer data is made analogous to the entry of the test company (see chapter 5.2.2.5). Here, a list with max. 10 customers can be created. The entries can be made before executing a test. This saves time at the customer’s site. Figure 20: Screen ‘Customer list’ 5.2.2.8 Plant list In order to have a reference to the plant name where the tests were made, the plant name can be entered here. The name length is limited to 40 characters.
NetTEST II Menu Guide 5.2.2.9 Segment list The submenu Segment list has, under Test protocol, the same task as the menu point under Line test. The functionality is therefore analogous to the one described in 5.2.1.1. 5.2.3 System configuration Figure 22: Screen ‘System configuration’ System configuration is for device specific settings, like e.g. parameterization of the serial interface, time settings, firmware update and extended parameters.
NetTEST II Menu Guide 5.2.3.2 Device properties Figure 23: Screen ‘Device properties’ With the menu Device properties the version and serial number is displayed. Additionally the options DP Master and Online functions can be activated if the appropriate license code is available. Figure 24: Screen ‘License code’ If a wrong license code is entered and confirmed with the key the indicated license code changes to "------".
NetTEST II Menu Guide 5.2.3.3 Date / Time To furnish the test protocols with time and date indications, NetTEST II is equipped with a quartz clock. In the submenu Date / Time, the clock can be set. The quartz clock is fed from the battery. If this battery should be empty or removed, the clock is energized by a maintenancefree capacitor. This capacitor provides the clock with energy for about 2 weeks. If within this period of time the battery pack is not charged, time settings are lost.
NetTEST II Menu Guide 5.2.3.4.2 PWR off time To save battery power, NetTEST II can be programmed by the PWR off time function with a time, after which the tool switches off automatically. The selection is made by the keys. The character '~' in the selection means, the system does not shut down. For the creation of test protocols in large plants, the offtime should be set to 30 min., to make sure that e.g. test results of the Test with no term. needed for the following Test with 1 term.
NetTEST II Menu Guide 5.2.3.5 Load parameters In the submenu Load parameters the user can receive parameter data sets from the PC. (see chapter 6.4 for procedure) The parameter data set comprises all parameters that are or may be set by the user of the NetTEST II.
NetTEST II Menu Guide 5.2.3.7 Firmware update The submenu Firmware update enables you to load possible firmware updates onto the test tool NetTEST II (see chapter 6.4). A fully charged accumulator is to be used, as the update process must not be interrupted. With a transition rate of 19.200 Baud the process takes approx. 12 min. 5.2.
NetTEST II Menu Guide 5.2.4.2 Receive GSD File To prepare reception of GSD files sent from a PC, the following steps must be performed: Start your terminal program on your PC Settings of the terminal program analogous to settings of NetTEST II (see chapter 5.2.3.

The minima and maxima values measured here are saved and displayed. The rotation time is an unambiguous indicator for performance problems, i.e. in a sporadic non-functional DP network.
System with online functionality 8.4 Signal level measurement Figure 64: Signal level measurement The NetTEST II measures the RS485-driver output level of each individual DP Slave and displays them in a bar graph. Below the bar graph the DP Slave address is indicated. Above the bar graph the actual RS485-driver output level appears in Volt. The minima and maxima values are stored right beside the bar graph as a scale line symbol. The rotating slash indicates the DP Slave actual measured.
System with online functionality The level measurement can be conducted by means of the current livelist or a defined filter. Figure 65: Selection menu Signal level measurement 8.4.1 Measurement with livelist For all DP Slaves contained in the current livelist a level measurement is performed. 8.4.2 Measurement with filter For Measurements with filter the bar graph display can be adapted to the spatial distribution of the network. A filter consists each of a name, a list of stations and their order.
System with online functionality 8.4.2.1 Define filter In the menu Define filter network specific data can be configured for the subsequent Level measurement. The data is stored in the data base under the selected filter name. In the following every single step for the filter definition is described: 1. A filter name with up to 30 characters can be defined: Figure 67: 2. In the DP Slave list the DP Slaves for the level or measurement can be selected.

System with online functionality 8.6 Event log Figure 71: Screen ‘Event log’ In the menu Event log the NetTEST II analyses the data traffic between DP Master and DP Slaves and shows all changes of the communication state for every DP Slave. The Event log is depicted in the form of a table.
System with online functionality 8.7 Event count Figure 72: Screen ‘Event count’ A problematic DP Slave, detected by the event log, can be examined in detail by the Event count function. The function event count displays in principle the same events as the Event log, but the status changes of the DP Slave can be analysed in detail. The following events are counted (0 - 99999): - DATA_XCHG_RES (DATA) Station is in state DATA_EXCHANGE. - NO_RESPONSE (DATA) DP Slave doest not respond.
System with online functionality 8.8 Diagnostic event Figure 73: Screen ‘Diagnostic event’ The Diagnostic event is an extended function of the Event count and provides the detailed analysis of an event. NetTEST II offers a selection of 6 different events that may be triggered. With the occurrence of the selected event all relevant data are displayed. Depiction is in plaintext as far as possible, depiction in binary / ASCII mode is also possible.
System with online functionality 8.9 Settings Figure 74: Screen ‘Settings’ In the menu Settings the following properties regarding the online functions may be selected: - - - - 76 Livelist hold (Yes / No, Default: No) If the livelist hold is activated, also sporadically detected DP Slaves at the PROFIBUS are stored in the livelist. Level timeout (2s, 5s, 10s, 60s, ~, Default: 2s) If the adjusted level time expires, the level measurement is proceeded with the next DP Slave.
Operation of the Battery Charger 9 Operation of the Battery Charger The battery charger comes in two components: a desktop battery holder and a plug charger. Connect the desktop holder with the plug charger. Insert a NetTEST II battery into the battery holder. Now plug in the charger plug into a 230 VAC mains socket. Check the charging process by means of the control LED of the battery charger, it is a “time charger”. Charge time starts with mains ON and lasts for approx. 6 hours.
Tips & Tricks 10 Tips & Tricks 10.1 Cable Lengths in PROFIBUS segments The maximum cable lengths of PROFIBUS segments are specified in the standard EN 50170, part 2, in dependency from the transmission rate used. Here, the indicated value applies only for segments with copper cables type A, without using repeaters. The following table shows the maximum segment lengths, depending on the baud rate: Transmission rate 9.6 Kbit/s 19.2 Kbit/s 45.45 Kbit/s 93.75 Kbit/s 187.5 Kbit/s 500.0 Kbit/s 1.5 Mbit/s 3.
Tips & Tricks 10.3 Use of stub lines When speaking about stub lines, one must distinguish between active and passive stub lines. Active stub lines can be, e.g. repeaters or optical couplers. They do not have any negative influence on the signal quality of the bus. Passive stub lines, however, (e.g. bus terminals or simple cable stubs), have to be avoided in every case.
Pin Assignment 11 Pin Assignment NetTEST II disposes of only one 9-pin D-SUB connector. This can optionally be switched to PROFIBUS or RS232 mode.

Problematic Slaves 13 Problematic Slaves Currently, KUNBUS knows of four PROFIBUS DP Slaves with problematic bus behaviour: These are, in particular, the following systems: Pepperl & Fuchs DP/PA-Koppler KDF2 Beckhoff / Wago older model of bus terminal (97-98) Siemens ET200 B older model (96-98) IFM-Electronic DP/ASI-Gateway AC 0005/AC 0006 The problems result either from capacitive / inductive screening measures on the PROFIBUS signal lines, or from excessively long spur lines within the DP
Frequently Asked Questions: FAQ 14 Frequently Asked Questions: FAQ Can NetTEST II also make measurements beyond a physical separation of the bus (e.g. via repeaters or optical couplers)? No, physical measurements via such bus connectors are not possible, as these completely disconnect the segments by its incorporated drivers.
Frequently Asked Questions: FAQ How is the connection to be made, if only participants with PG screwing resp. screw terminals are connected to the bus? Should these participants be placed at both bus ends, the user must provide an additional D-SUB connector for test purposes. KUNBUS will soon offer a spring clip terminal block as accessory for the one core connection. Please ask our sales department for availability.
