empowering communication

Complexity and variability make optimizing your Real-Time Ethernet network a challenge, because faults need to be found and eliminated as quickly as possible. With Hilscher's netANALYZER and netMIRROR you can reliably monitor your data traffic.

Network and Communication Diagnostics

Complexity and diversity make monitoring and optimizing your Real-Time Ethernet network a challenge, because faults need to be found and eliminated as quickly as possible.

Our netANALYZER and the intuitive graphics software, netANALYZER Scope, give you a full overview of your Ethernet networks at all times—regardless of the protocol or application in use. This allows you to measure important key data such as subscriber lists, alarms, process values, network usage and telegram jitter without any impact on the network or PLC. netANALYZER can also remain autonomous in a system for a longer period of time with the help of the trigger function. When defined events occur, netANALYZER automatically creates a telegram snapshot.

netMIRROR is the simple, reliable and efficient solution for integrating permanent test access point (TAP) into your industrial communication networks without affecting the network, whether for monitoring your traffic, quick troubleshooting or as part of your digital services.

Analysis Devices FAQ

What are Hilscher analysis devices?

Hilscher analysis devices are industrial tools for diagnosing and monitoring Industrial Ethernet networks. They help identify communication issues, quickly locate network faults, and ensure the availability of machines and systems.

What tasks do Hilscher analysis devices perform?

  • Real-time monitoring of network traffic
  • Analysis of communication protocols (e.g., PROFINET, EtherCAT, etc.)
  • Fault diagnosis in the event of disturbances or failures
  • Long-term recording for documentation of network conditions

Which analysis products does Hilscher offer?

  • netANALYZER – analysis device for Industrial Ethernet (PROFINET, EtherCAT, EtherNet/IP, etc.
  • netSCOPE – software extension for the netANALYZER enabling automated data analysis without interfering with the PLC or device software

Which protocols can be analyzed using Hilscher analysis devices?

  • Industrial Ethernet: PROFINET, EtherCAT, EtherNet/IP, Modbus TCP, CC-Link IE Field
  • IoT interfaces: Analysis of protocols such as OPC UA or MQTT (in combination with edge devices)

What are the benefits of Hilscher analysis devices?

  • Fast fault localization in case of network issues
  • Reduced downtime through precise diagnostics
  • Real-time-capable recording, even in highly dynamic networks
  • Cost efficiency due to reduced maintenance and service effort
  • Support for retrofit and modernization of existing systems

How does the netANALYZER work?

The netANALYZER is inserted into the Industrial Ethernet network and records telegrams in real time. With nanosecond-level time resolution, it enables detailed analysis of cycle times, jitter, and packet loss—ideal for commissioning, monitoring, and troubleshooting.

What role does netSCOPE play?

netSCOPE is the matching software for the netANALYZER. It visualizes recorded data packets, displays protocol details, and provides dedicated diagnostic views for PROFINET, EtherCAT, EtherNet/IP, and other protocols.

In which applications are analysis devices indispensable?

  • Commissioning of new machines and systems
  • Maintenance and service in production environments
  • Troubleshooting of unclear communication issues
  • Quality assurance through continuous monitoring
  • Retrofit projects to securely integrate legacy and modern networks

Who are Hilscher analysis devices intended for?

  • Machine and plant builders commissioning networks
  • Service and maintenance technicians who need to resolve failures quickly
  • System integrators managing heterogeneous networks
  • Manufacturing companies aiming to ensure high system availability

Why are Hilscher analysis devices important for Industry 4.0?

They increase transparency in complex communication networks and provide a reliable data basis for predictive maintenance and process optimization. As a result, they are a key component of modern smart factory and IIoT concepts.
