Diagnostics, troubleshooting and monitoring of ETHERNET - Type: Ethernet Diagnostics BASIC

Stable Production Starts with Stable Communication

Most companies only start dealing with Ethernet when applications slow down or data exchange in the Ethernet network becomes unstable. We can measure and diagnose Ethernet earlier. We have completed thousands of industrial network measurements and bring many years of hands-on experience from real industrial environments. We don’t just measure copper cables. We help companies identify and eliminate the root causes of unstable Ethernet communication, uncover reasons for slow applications, outages, or security threats. Our technicians analyze your network, identify weak points, and prepare a clear report with specific corrective recommendations. Whenever possible, we eliminate the issues immediately. Preventive Ethernet measurement is a recommended part of annual production line maintenance and reduces the risk of unexpected downtime.

Professional Analysis and Diagnostics of LAN and WLAN Networks

• Are you experiencing a slow Ethernet network?
• Do you want to know the quality of your Ethernet network?
• Do you want to prevent unexpected failures?
• Have you imported an older production line from abroad and want to know the condition of its Ethernet network?
• Are you about to take over a production line from a supplier and want to verify the quality of their work?
• Are you handing over a line or machine to your customer and want to prove that the delivered network is in proper condition?

One-Time Diagnostics – Choose a Program According to Your Situation

• quick preventive network check → BASIC
• occasional network outages → FOCUS
• regular outages or complete network failure → STANDARD
• preventive measurement of all networks → PREVENT

BASIC – Quick Preventive Network Check (2 hours of technician work)

I want to know the condition of the network.

• measurement of basic communication parameters
• error rate check
• cabling condition evaluation
• identification of initial warning signals

Ideal when:

• you want preventive measurement
• the network is running without outages
• you have a new machine or made minor modifications

FOCUS – Solving Initial Outages (4 hours of technician work)

Problems are starting to appear and I want to know why.

• analysis of network instability
• measurement at multiple network points
• proposal of corrective measures
• if possible, we resolve the issue and eliminate the fault

Ideal when:

• the network occasionally drops
• major network changes were made
• the issue can be reproduced

STANDARD – Systematic Full-Day Diagnostics (7 hours of technician work)

The network frequently fails or is completely down, and I need to find and eliminate the root cause.

• comprehensive diagnostics of individual network segments
• hypothesis verification
• localization of the real root cause
• proposal of corrective measures
• if possible, we resolve the issue and eliminate the fault

Recommended when:

• failures occur regularly
• the network is completely down and cannot be restarted
• the topology is complex
• previous interventions have not helped

PREVENT – Preventive Inspection of All Industrial Networks (1+ days)

To prevent unplanned downtime, we recommend annual preventive network inspection.

• inspection of selected critical or all networks
• measurement of multiple communication types (PROFINET, PROFIBUS, CAN, AS-i, Ethernet/IP)
• identification of risks and weak points

Prevention is cheaper than unplanned production downtime.

EXPRESS Mode – Priority Intervention in Case of Network Failure

If you experience a sudden network failure and need immediate assistance, we respond without delay.

In EXPRESS mode:

• your case receives top priority
• other scheduled interventions are rescheduled
• we dispatch in the shortest possible time (ideally immediately or within hours)
• the issue is handled by an experienced specialist

The goal is to restore stable production operation as quickly as possible.

EXPRESS mode is subject to a priority surcharge and is added to the STANDARD service.

Measurement Reports

All one-time diagnostic services include a service report describing the situation, listing network stations, measured signals and values, warnings about undesirable phenomena, topology (PROFINET only), measurement details, and basic improvement recommendations if applicable. Upon request, we provide a detailed paid report including in-depth analysis and solution options.

Permanent Monitoring of Industrial Networks

In addition to one-time diagnostics, we offer permanent network monitoring that helps:

• monitor networks 24/7
• detect gradual network degradation
• provide faster alerts and interventions
• analyze long-term statistics

Available 24/7 network monitoring options:

LOCAL – On-Site Ethernet Network Monitoring

We install a permanent Ethernet network diagnostics solution directly at your facility, including a monitoring system that provides continuous supervision of networks, network components, and other stations within OT/IT infrastructure. We do not guarantee that Ethernet will never fail. However, if the network experiences downtime, excessive data load, IP station dropouts, or similar issues, you will be immediately informed via alarm and event overview.
