Profibus Diagnostic & Troubleshooting Device

Supports PROFIBUS cable testing, physical signal & protocol analysis

The PROFIBUS Tester 5 (BC-700-PB) is a powerful PROFIBUS diagnostic and troubleshooting tool for testing the cables, measuring the signals and analyzing the communication of PROFIBUS networks. It is battery-powered and provides a graphical display, allowing for quick results when working in stand-alone mode. Optionally, also PROFIBUS PA network can be analyzed. In addition, the PROFIBUS Tester 5 supports the export of test results for advanced analysis.


Test PROFIBUS Cable, Signals, and Data, All-In-One Handheld Tester

  • Combination of PROFIBUS signal tester, oscilloscope, protocol analyzer, master simulator and cable tester functionality in a single handheld diagnostic tool
  • Includes stand-alone mode plus extended PC-based diagnostics
  • Suited for PROFIBUS installation, setup, commissioning, documentation, acceptance testing, network optimization, preventive maintenance, troubleshooting as well as laboratory tests
  • Ideal for first time users as well as for PROFIBUS specialists

Highly Mobile PROFIBUS Tester for Testing Even Without a Laptop

  • Battery-powered operation; testing while unplugged reduces risk of ground loops
  • Graphical display provides easy-to-understand presentation of test results
  • Comprehensive network tests are built-in to PROFIBUS Tester 5 without requiring a laptop PC

Enhanced Diagnostic Features in the Analytical Software

  • Many additional features for executing, analyzing and managing PROFIBUS tests (Trend, Topology Scan, Master Simulator, Oscilloscope, Frame Analyzer)
  • Quick Test and User-Controlled Test for easy network status assessment at the push of a button
  • Generation of test reports describing the actual status of the PROFIBUS installation

Optional Measuring Adapter for MBP (Manchester Coded Bus Powered) Signals

  • Specific signal analysis supporting MBP Physics (feeding voltage, signal deviation, signal polarity, bitrate divergence)
  • Complete protocol analysis directly at the PROFIBUS PA segment

D-Sub Service Interface for PROFIBUS DP

Application example:

Interface for Providing an Access Point to Test PROFIBUS Networks if the D-sub Connectors have no Service Socket or if the Devices are Connected via Terminal Block

Provides an access point for testing PROFIBUS networks if the D-sub connectors have no service socket or if the stations are connected via terminal block.

  • Allows Testing the Bus During Operation
  • Exchange of Bus Devices at the Beginning or End of the Bus Without Causing Problems on the Bus


The service interface is top hat rail mounted. An external 24 VDC power source is required for power supply to the terminating resistor in the PROFIBUS connector included in the package. The service interface can thus be used 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, the service interface offers the possibility to exchange the first and last bus stations without causing problems on the bus.

Included in Package

PBMB adapter and 90° angled PROFIBUS connector with switchable terminating resistor, strain relief and screw terminal technology.

M12 Service Interface for PROFIBUS DP

Application example:

Interface for Providing an Access Point to Test PROFIBUS Networks With M12 Connectors

Provides an access point for testing PROFIBUS networks with M12 connectors.

  • Allows Testing the Bus During Operation


The service interface is inserted between two bus stations. When not in use, the service output of the T piece is closed with an end cap. At baud rates of 1.5 Mbit/s or higher, use the supplied cable to ensure that the required minimum distance between bus stations is maintained.

Included in Package

T piece (protection class IP68) with end cap and a 1 m DP cable fitted with a male/female M12 connector on each end.
