24h Emergency Service for Fieldbus Failures
Fast troubleshooting and recovery when communication goes down. Response within 24 hours, 7 days a week.
Your Fieldbus Problem. Our Fix.
Sporadic dropouts, slow response times, or a complete failure. We know the typical fieldbus problems and we fix them for good.
"Our system has sporadic communication dropouts."
Physical bus measurement: We measure signal quality and telegrams, find the weak point, and fix it for good. Often it's a faulty connector or missing bus termination.
"Our system response times keep getting slower."
Network analysis: We identify bottlenecks, overloaded segments, and faulty nodes, then optimize the configuration for peak performance.
"We want to migrate from Profibus to Profinet."
Migration planning: Step-by-step transition with minimal production interruption, from inventory to commissioning.
"We want to avoid unplanned downtime."
Maintenance contract: Annual network measurement with trend analysis so you spot degradation before it becomes a failure.
"Our fieldbus is completely down. Production has stopped."
24h emergency service: Immediate remote diagnostics or on-site deployment. We get your communication back up as fast as possible.

Frequently Asked Questions about Fieldbus Diagnostics
Profibus and Profinet are industrial communication protocols for networking automation devices like PLCs, drives, and sensors in production plants. Profibus uses serial RS-485 communication, Profinet is based on Industrial Ethernet. Both standards are managed by the PROFIBUS User Organization (PNO).
Typical issues include sporadic communication dropouts, slow response times, EMC interference, cable defects, faulty connectors, incorrect bus termination, grounding problems, and address conflicts. The root causes are often physical and can be quickly identified with professional test equipment.
We analyze the network with professional diagnostic equipment from Indu-Sol (PROFItest, PROFINETinspector), measure signal quality, telegram timing, and bus parameters, identify weak points, and deliver a detailed report with prioritized recommendations.
Costs depend on the network scope: number of nodes, segments, and complexity. After a free initial consultation, we provide a transparent fixed-price quote.
Our emergency service responds within 24 hours, 7 days a week. For many issues, we can diagnose immediately via remote access. On-site deployments across Baden-Wurttemberg are available on short notice.
Yes, we analyze both Profibus DP and Profinet IO networks. For Profinet, we use network captures, topology analysis, real-time communication diagnostics, and infrastructure checks (switches, cables, connectors).
Yes, regular fieldbus checks are the best protection against unplanned downtime. We offer maintenance contracts with annual network measurement, trend analysis, and documentation so you catch problems before they happen.
Our focus is Baden-Wurttemberg, from Lahr through Offenburg and Freiburg to Karlsruhe. We also handle larger projects and emergencies nationwide.
