SCADA DATA DIODE / POWER & UTILITIES
Share the operating picture.
Protect the control boundary.
“SCADA data” can support reporting, maintenance, and security monitoring outside an operational network. A data diode may fit the outward reporting path when return commands are not required through that connection.

In plain language
SCADA stands for supervisory control and data acquisition. It combines observation with control. A design must distinguish a reporting feed from a control channel; they are not interchangeable.
UNDERSTAND THE REQUIREMENT
A reporting feed is not a control connection.
A power-generation site may publish output and equipment health “data” to a reporting team. A substation may share selected alarms for analysis. If the receiving system must also operate equipment, that two-way requirement needs a different or additional approved architecture.
Alarm and event visibility
Share relevant events with an external monitoring team. Preserve ordering and time information so the team can interpret them.
Substation analytics
Replicate approved operational information for asset analysis. Protection functions and control commands are outside this illustrative reporting use case.
Where it fits
Potentially appropriate for outward telemetry and reporting. A diode should not be inserted blindly into a control or protection path that requires two-way traffic.
FOR TECHNICAL TEAMS
Four checks before
you choose a design.
Bring these questions to the architecture discussion. A product’s supported connectors and tested configuration matter.
Explore protocol explanations →Flow-by-flow design
Identify telemetry, commands, time synchronisation and engineering access. Do not treat all SCADA traffic as one-way.
Protocol fit
Confirm the protocol, supported roles, security settings and data mappings with the proposed gateway.
Time and freshness
Specify timestamp handling, acceptable reporting latency and a clear indication when information is outdated.
Continuity and acceptance
Agree how link, receiver and power failures are handled, plus any project-specific assurance and operational requirements.
TURN ASSUMPTIONS INTO EVIDENCE
What should your POC test?
Test representative alarm bursts along with normal telemetry. Check the receiving view during an outage and after recovery. Evaluate the reporting path through an “industrial data diode” without experimenting on live protection or safety functions.
COMMON QUESTIONS
Before you
take the next step.
Can the control centre send commands through the same diode?
An outward-only diode cannot carry return commands. Clarify whether the destination is a reporting centre or a control centre before selecting the architecture.
Does this imply approval for every utility project?
No. Suitability and approvals depend on the specific system, customer and applicable project requirements.
What should we provide for an initial discussion?
A high-level description of source and destination, telemetry types, expected rates, direction and project stage is enough to begin.
