Introduction

1.1 About the PROFIBUS Tester 5 (BC-700-PB)
The PROFIBUS Tester 5 (BC-700-PB) is a powerful tool that allows full testing of the bus physics and bus communication on PROFIBUS DP and PROFIBUS PA segments (option). Using the integrated master  simulator, you can also test the bus physics if the PLC is currently not in operation. In addition you can check individually check “suspicious” bus stations. The cable test function examines the cabling in PROFIBUS  DP segments. It locates unwanted reflections on the line and verifies proper termination of cable segments. The tool is powered either by its built-in battery or through an external AC adapter.
The PROFIBUS Tester 5 (BC-700-PB)s the first battery-powered tester, which combines the assessment of bus physics and bus communication as well as cable testing in one device. It is therefore the only and truly  mobile PROFIBUS diagnostic tool.

1.4.4 Adapter for testing PROFIBUS PA networks
The optional plug-in adapter (including test equipment set) for PROFIBUS PA networks enables the BC-700-PB to analyze electrical signal quality and data communication in PROFIBUS PA installations.
The BC-700-PB in conjunction with the adapter BC-700-H1 is the proper test tool for identifying basic installation errors and defective PROFIBUS PA stations.

License for PA option
If you want to use the PA-Adapter BC-700-H1 with your BC-700-PB you need a corresponding license (upgrade). This license is related to the serial number of your device. When ordering the PA option we kindly ask you to provide us with the serial number of your BC-700-PB (see also Licenses).
Before using the PA adapter
Before using the PA adapter for the first time read carefully section PA- Adapter BC-700H1 –before you start. Activate the PA license on your device and preform the 28 required updates.
Note
Note the PROFIBUS PA-specific notes in sections Connecting to PROFIBUS PAnetworks, Display and controls in stand-alone mode and Licenses.

1.4.5 Spare battery
Intensive use of BC-700-PB during the work day may exhaust the rechargeable battery faster than expected. In addition charging and discharging will typically wear out the battery pack over the time (refer to Notes  on battery use). BC-700-PB has an internal energy management. If the measures for energy saving are not sufficient or are perceived as a disturbance it is recommended operating on the device in conjunction with  an external power supply. Each unit comes with a rechargeable battery of type PA-L27.K02 which can be ordered from any vendor and replaced if required.

1.4.6 Service interfaces for PROFIBUS DP
1.4.6.1 Connection type D-sub
The D-sub service interface provides a PROFIBUS access point for testing if the existing D-sub connectors have no service socket or if the bus stations are connected via a terminal block. The service interface can  power the terminating resistor of the D-sub connector. You can thus use it as an active bus termination at the beginning or end of the bus.
If the PLC allows dropping and adding bus stations on the live bus, you will need this external bus termination to be able to exchange the first and last bus stations without causing problems on the bus.
The compact unit is rail mounted like a terminal block and powered by an external 24 VDC power supply. The package includes an 90° angled PROFIBUS connector with a switchable terminating resistor.

Softing order number: ACA-NN-006037

1.4.6.2 Connection type M12
The M12 service interface comprises an IP68 rated T piece, an end cap for the service output of the T piece, and a 1m PROFIBUS DP cable fitted with a male/female M12 connector on each end.

Power up and down the device

Install PROFIBUS Diagnostics Suite before connecting to a PC
Before connecting the BC-700-PB for the first time with a PC make sure the latest PROFIBUS Diagnostics Suite and the required drivers are installed on your PC. For detailed installation instructions refer to the  Quick Startup Guide supplied with your PROFIBUS Diagnostics Suite CD-ROM.
Always connect device directly to an USB port
Use the included USB cable to connect the tool to a PC or notebook. When you use external USB hubs, notebook docking stations or USB 3.0 ports for connection, problems may occur.

2.1 Power-up

1. Acclimate to room temperature
   Before being connected to the AC mains power, the PROFIBUS Tester and the AC adapter must be acclimated to room temperature to avoid condensation. This may take up to 60 minutes.

2. Power-up
   Make sure that you have either connected it to a power supply, or that you have inserted the battery. Then switch on the tool by pressing the power key at the upper front edge. The display lights up and self-test  starts.

3. Check battery charge level

The display shows the battery charge level indicator . If the charge level is too low, recharge the battery as described in Charge battery.

Hint
We recommend operating the device solely using the wide-range power supply supplied or using the integrated battery to avoid equalizing currents which can falsify the test results.
The tool is powered by a built-in three cells lithium ion accumulator with 11.1 VDC. Alternatively the tool can be powered by 24 VDC through the external wide-range power supply.

2.2 Power-on behaviour without USB connection
If not connected to an USB port, the BC-700-PB starts up in stand-alone mode (see Display and controls in stand-alone mode) and is immediately ready for testing. During program start-up the splash screen is  shown for a few seconds and displays “USB NOT CONNECTED”: 

2.3 Power-on behaviour when USB connected
Install drivers before connecting to USB
Install the PC software “PROFIBUS Diagnostics Suite” and the corresponding drivers before connecting for the first time to a PC or to a notebook. You will find software and drivers on the PROFIBUS Diagnostics  Suite CD-ROM.
The internal battery of BC-700-PB is NOT charged when being connected to a USB port.
On successful completion of the self-test, the BC-700-PB displays:

When you start the PROFIBUS Diagnostics Suite control and evaluation software on your computer and select the PROFIBUS Tester and a network for testing in its user interface, the test tool switches to PC mode.  At this point, a firmware update instead of using the control and evaluation software might be started automatically. See Firmware update.

2.4 Power-off and sleep mode
Power-down
Press power key for more than three seconds in order to power-down the device. There is no power consumption if the device is powered down. The device can be stored for long a period of time.
Activate sleep mode
If you want to change manually to sleep mode, shortly actuate the power key. During sleep mode the BC-700-PB is saving energy and the power key will blink slowly. If a measurement function is currently active, it is not possible to switch to sleep mode. Depending on the settings in energy management, the BC-700-PB may automatically change to sleep mode after a predefined period of time.
Return to normal operation mode
You can recover normal operation very quickly by shortly actuating the power key a second time. The lastly shown menu screen will be displayed which was active before changing to sleep mode.
Automatic power-down
If the BC-700-PB is in sleep mode for more than 2 hours, it will automatically power down.

Connection to PROFIBUS-DP

3.1 Basics
3.1.1 Note when testing a live bus
Test tool side effects
When you connect a test tool, side effects on the system under test are generally unavoidable. If the PROFIBUS is already disturbed to a certain degree or if Simatic Diagnostic Repeaters are used, the operation of the PROFIBUS might nevertheless be affected occasionally. Observe the following connection notes.

3.1.2 Connection types
There are several ways to connect a bus station to a PROFIBUS network:

• Using connectors
  D-sub connectors, most of which have an integrated terminating resistor and, optionally, an additional service socket
  M12 connectors for environments requiring increased IP ratings
  Special vendor-specific hybrid connectors; they are used in combination with special cables to supply power via the bus

• Using terminals for direct connection
  Due to the typical daisy-chain topology, the connection points of the bus stations are the only possible points for connecting the test tool in most cases.

3.1.3 Adapter cable
The BC-700-PB is supplied with the D-sub adapter cable ACA-NN-006032 Standard (light connector).
For testing on live systems the optional D-sub adapter cable ACA-NN-006031 is recommended. An M12 adapter set is optionally available, see D-sub adapter cable for testing live systems.
Only use original short cables
Use only the original short cables with special pin layout to connect the unit to a PROFIBUS network. Do not cascade more than two D-sub connectors with service sockets at the same time:

3.1.4 Strain relief
Avoid stress on connectors and bus stations
Avoid stress on connectors and bus stations which might be caused by the device’s own weight.
Possible measures to avoid stress are

• support,
• strain relief using cable ties or
• using a retaining hand strap. Fastening eyes are premounted at the bottom of the tester. You can fix them either at the bottom or at the top of the tester. The retaining hand strap is not part of the delivery.
  If avoiding stress is not possible, you need to select a different connection point to avoid damage.

3.1.5 Using the security lock port
When using trend logging, the BC-700-PB is typically operated in an unattended manner over a prolonged period of time. You can connect a Kensington lock to the security lock port to prevent your device being stolen. The Kensington lock is not part of the product delivery and must be purchased separately. To use the Kensington lock, refer to the product manual. Tie the Kensington lock cable to a fixed object and install the other end of the cable to the security lock port.

3.1.6 Test Locations
Basically you can carry out tests anywhere on a physical PROFIBUS segment using the BC-700-PB.
Note that the use of repeaters creates separate physical segments that each needs to be measured individually.
For the best and most informative signal quality results, perform the tests at the beginning and end of each physical segment. If these test results indicate problems that cannot be clearly classified immediately, you should carry out one or more additional tests at the center.
3.2 Simple connection for tests during system shutdown
If all bus stations provide D-sub connectors with an additional service socket, you can simply plug in the BC-700-PB at that socket. If a D-sub connector does not provide a service socket, you can plug in the Dsub adapter cable  underneath. Keep in mind that you do not cascade more than two D-sub connectors (see Adapter cable).
When using M12 connection technology, the M12 adapter cable is looped into the bus. It is essential to ensure proper termination at the beginning and end of the bus by using the terminating resistor provided with the M12 adapter set.
Shut down complete installation before connecting
All these simple connection types will divide the bus. You therefore need to shut down the PLC and all the devices connected to the PROFIBUS; in other words, you need to shut down the whole installation.

3.3.3 Connection Type M12
To test a live PROFIBUS, you will need additional service interface of the type BC-M12DP-PB (see Adapter set for M12 connection technology).
Tests on a live PROFIBUS are only allowed on bus segments providing D-sub connection technology.
Only D-sub connectors with service socket can be used as connection points for the test tool. For this reason, tests can often only be performed at a bus end.

Connect T-fitting between existing cable and 1 meter connection cable
Always connect one end of the T-fitting to the already existing cable and the other end to the 1 meter connection cable which is supplied with the service interface.
Do not screw the T-fitting of the M12 service interface directly onto a slave.

3.4 Master simulator, topology scan and cable test
Master simulator
The master simulator allows checking the bus cabling and the station addresses during installation and commissioning, when the PLC (master) is not in operation yet. In addition, you can use this mode to check individual suspicious bus  stations that have been disconnected from the bus.

Topology scan
The topology scan determines the sequence and distances of all passive bus stations (slaves). This feature requires correct bus cabling, a very good signal quality, and a connection point located directly at the beginning or end of the bus.
Cable test
The cable test assesses the wiring and can be used to determine a faulty cable location (e.g. short circuit) by means of reflection test. All three features can only be used during shutdown of the installation. The D-sub cable ACA-NN- 006032 which is included in the standard scope of supply must be used. As long as communication is detected on the bus, i.e. at least one device is an active master, the functions are disabled. Check If necessary, disconnect every single  active device (PLC, MPI and, if necessary, diagnostic repeaters) from the power supply or the bus. If an active device is at the end of the bus you want to test, its PROFIBUS connector needs to be unplugged and connected directly to the  PROFIBUS Tester 5 (BC-700-PB). The bus termination in the device connector will then be powered by the BC-700-PB.

Figure 20: Connection points for topology scan and cable test
Bus stations must only be disconnected from the power supply or the bus during shutdown of the installation.
The three functions can be started also when the BC-700-PB is disconnected from the bus. If you then connect the BC-700-PB to a live bus despite the yellow bus status bar indicated by the PC software, this can cause bus communication  problems or a shutdown of the installation.

Special case: active devices at both ends o the bus during topology scan
On the very rare occasion when there is an active device at each end of the bus, do the following:

1. When using D-sub connection:
   a. Additionally switch on the terminating resistor in the D-sub connector of the last slave.
   b. Make sure the outgoing cable to the active device at the bus end is connected to the outgoing connector (marked with “OUT”, an outgoing arrow, or “A2/B2”).
