PROFIBUS

Field Service

These may be signs of an impending production stoppage. Downtime can cost you a lot in time and money. UNIS Group offers you the solution. With our all-in-one on-site service, we help keeping your production process running. We prepare you for the future and offer a total solution to reduce downtime.

Unique PROFIBUS tool

A UNIS Group specialist will visit you to map out the PROFIBUS network and thoroughly establish the extent of your industrial installation. A fault analysis is carried out with the help of a specially developed PROFIBUS tool. The tool analyses your PROFIBUS network based on the functionalities below:

  • Bus Monitor for an overview of the available PROFIBUS nodes

  • Oscilloscope to assess the signal level

  • Bar charts indicating the quality of the PROFIBUS nodes

  • Topology scan

  • Reporting

  • Ability to act as DP master

The information from the fault analysis reflects the quality of your PROFIBUS network. You discover the weak links of your installation and gain insight as to how to improve it. Clear reporting allows you to locate and fix the defect more quickly in case of a malfunction. If the breakdown occurs sporadically, we can monitor your PROFIBUS network 24/7 to locate where the problem arises.

Emergency solution

Noise, reactions, voltage dips, problems with sealing resistance, double addresses, wire breaks and configuration glitches are classic errors that can shut down a PROFIBUS network. You want to fix this as soon as possible. Every minute that your production is down, is a precious minute. In addition to maintenance, you can also call on UNIS Group for emergencies.

  • We check the resistance of PROFIBUS cables.
  • We read the master to thoroughly analyze the overall system.
The most common problems we encounter are:
  • Physical issues with modules, such as faulty components.
  • Low voltage
  • Incorrect or wrong connections
  • Improperly connected cables between modules.
The duration of the resolution depends on the nature of the problem, but it is possible for it to be resolved on the same day. If it takes longer than the same day, we also offer the option for you to address the problem yourself with the help of our analysis and advice.
Yes, after a PROFIBUS analysis, you will always receive a report. In some cases, this report is handed over on-site, but unfortunately, this is not always possible. For more comprehensive reports, we deliver the report - including all analyses - at a later time.
Yes, we offer the option for 24/7 monitoring, which is achieved by installing a module that continuously monitors your processes.
