Digital substations based on IEC 61850 / IEC 61869 have raised the level of performance and standardization in protection, control, and metering. On the other hand, they have also increased the need for network visibility, fast diagnostics, and the ability to perform precise field testing — especially when dealing with GOOSE, Sampled Values (SV), and time synchronization via PTP (IEEE 1588).
This is exactly where the CE-MNET4 stands out: a versatile tool that combines multiple functionalities in a single device for power system testing and network diagnostics in digital substations — with a differentiator that literally weighs in favor of productivity: it is ultra-portable, lightweight, and weighs only 2 kg.

What is the CE-MNET4 and why it matters in daily operations
The CE-MNET4 was developed to support teams in scenarios that demand speed and precision, such as:
- commissioning of IEC 61850 networks
- maintenance and periodic validations
- troubleshooting when everything looks correct in theory, but the bus does not behave as expected
- field and laboratory testing, without depending on heavy structures
By bringing together testing and diagnostic resources in a compact device, it reduces travel, shortens maintenance windows, and accelerates technical decision-making — something critical in environments with high availability requirements.
Ultra-portable (2 kg): mobility that turns into productivity
In projects and operational routines, portability is not a detail — it is a strategy. A 2 kg device changes the work dynamic because it allows teams to:
- take the tool to where the problem is — not the other way around
- perform quick checks at multiple points in the substation
- gain efficiency in field teams, especially during short outage windows
This “grab-and-go” profile increases agility without sacrificing technical capability.
Publishes and subscribes to GOOSE and Sampled Values (IEC 61850 / IEC 61869)
Two pillars of a digital substation are:
- GOOSE: high-priority event/control messages
- SV (Sampled Values): current/voltage samples on the process bus
The CE-MNET4 is capable of publishing and subscribing to GOOSE and Sampled Values messages according to IEC 61850 / IEC 61869. In practice, this is crucial for:
- validating communication and publish/subscribe behavior
- testing interoperability and message consistency
- simulating operating conditions and verifying system responses
- quickly confirming whether the problem is related to the network, configuration, or integration
Time synchronization via PTP (IEEE 1588): when time is part of the test
In digital environments, time synchronization stops being a “nice to have” and becomes a requirement for stability and consistency — especially where SV and time-sensitive applications are involved.
The CE-MNET4 enables time synchronization through PTP (IEEE 1588), supporting teams that need to test and validate the ecosystem with confidence while maintaining traceability and analytical consistency.
Traffic monitoring and analysis: capture, see, and diagnose
In addition to testing, the CE-MNET4 includes monitoring modes that:
- capture substation network traffic
- analyze the packets circulating through the bus
This is what turns “suspicions” into diagnosis: you start seeing what is really happening, based on traffic evidence. For troubleshooting, this kind of visibility reduces downtime and increases correction accuracy.
Where the CE-MNET4 delivers the most value (typical applications)
The device tends to be especially useful when the goal is to:
- accelerate IEC 61850 commissioning with objective tests
- strengthen quality in maintenance and preventive validations
- reduce MTTR (mean time to repair) in network/process bus incidents
- bring diagnostics to the field with practicality and low operational friction
