Competent troubleshooting of fieldbus technology

We are your experienced partner and solve your problems in all aspects of fieldbus technology. Fieldbus systems have been used since the 1980s to reduce the number of wires needed in automation systems and to connect intelligent modules. Today, almost 100% of all new plants are equipped with fieldbuses.


The comprehensive fieldbus products and services of Leadec for existing systems ranges from troubleshooting through on-site testing and acceptance measurements to training courses for maintenance staff. Another focus is on initiating complementary diagnostic tools for Profinet, Profibus, CAN, Ethernet, AS-Interface and ESD, etc.

Systematic troubleshooting

Many malfunctions are caused by installation faults. These are defects that arise during the installation or expansion of the bus system, e.g. due to faulty test jacks. Most of these faults can be detected by visual inspection for which we have designed a softwareassisted procedure. The LeadecNetApp based on this provides you with a structured process to support systematic troubleshooting.

Permanent condition monitoring

Permanent condition monitoring has proven its worth in order to detect signs of wear and tear on a bus system or network caused by aging. Various testers are available for this purpose, which monitor the telegram traffic. The proven testers P-QT 23 for Profibus, PN-QT 20 for Profinet, C-QT 15 for CAN, A-QT 15 for AS-Interface and ESD-QT 16 for electrostatic discharge have been supplemented by the QT-Manager for automated troubleshooting.
