Features

• All-in-one
  The PROFIBUS Tester 4
  combines a signal tester, a storage oscilloscope, a protocol analyzer,
  and a master simulator into a single tool. This tool is designed for use
  in a wide range of applications – from setup and commissioning,
  documentation, acceptance testing, and optimization to preventive
  maintenance, troubleshootings and laboratory tests. In addition, the
  PROFIBUS Tester 4 can be used without a notebook and is able to run
  comprehensive network tests in stand-alone mode.

• Also suitable for less experienced users
  With
  a single mouse click (PC mode) or a single push of a button
  (stand-alone mode) a user is able to initiate a full examination of a
  PROFIBUS network including automatic signal and protocol analysis. A
  summary of all results is displayed to the user in a very intuitive
  manner. In PC mode, the software package has been designed to emphasize
  the all-important ease-of-use aspect while at the same time preserve the
  more in-depth diagnostic features required by networking experts. This
  makes the tool ideal for both less experienced users and fieldbus
  specialists.

• Intuitive use and clear readings
  The
  PROFIBUS Tester 4 automatically detects the baud rate or open circuit
  voltage immediately after connection to the PROFIBUS. In stand-alone
  mode, the bus can be tested using the Live Status functionality. The PC
  software provides many additional features for executing, analyzing, and
  managing bus tests. A status bar continually shows the current bus
  state. Using the Network Status function, the bus can be tested with a
  Quick Test or a user-controlled test. The Topology Scan feature
  determines the overall cable length and the cable length between slaves.
  The test results can be documented in a detailed test report. The
  Long-Term Trend view is used for detecting sporadic faults. In the
  Oscilloscope and Frame Analyzer views, experts can perform in-depth,
  detailed analysis. For bus and device tests with the integrated master
  simulator, only the baud rate needs to be specified – no configuration
  or parameterization is required.
