How SkarBroker works
One message. Every system that needs it.
MQTT uses a publish and subscribe model. Each connected client sends or receives messages through the broker using named topics.
Publish to SkarBroker
The source publishes a message to a topic such as factory/line-01/status. The private broker routes it to the right subscribers.
Put data to work
MQTT clients and integrations in HMI, SCADA, dashboards or analytics tools subscribe to the updates they need.
Made for connected industry
The data layer between your machines and your decisions.
Industrial data often sits across different devices and software. SkarBroker gives MQTT enabled systems a shared route, helping teams build useful Industry 4.0 workflows around existing operations.
Where a device does not speak MQTT directly, an appropriate gateway or software connector is needed.
PLC data acquisition
Publish machine states, counters and process values from supported PLCs or gateways.
HMI visibility
Make selected live values available to operator screens through MQTT integration.
SCADA integration
Move plant data into supervisory applications using suitable MQTT clients or connectors.
Industry 4.0 insights
Build remote monitoring, production tracking, energy views and analytics pipelines.
Why a private broker
A dedicated path for industrial messages.
Keep the messaging layer aligned with your plant, applications and deployment needs.
Dedicated environment
Your MQTT broker runs on a VPS allocated for your deployment, with access and configuration shaped around your project.
Flexible integrations
MQTT topics allow multiple authorized clients to use the same data without point-to-point wiring between every application.
Built around operations
Connect shop-floor signals to monitoring and analysis while keeping PLC control and SCADA supervision in their existing roles.
Frequently asked questions
SkarBroker, explained.
What is a private MQTT broker?
It is a dedicated message exchange point for devices and applications. Publishers send data to topics; subscribers receive the topics they need. SkarBroker is hosted on a VPS for your industrial data flow.
Can it connect PLC, HMI and SCADA data?
Yes. An MQTT capable PLC or edge gateway can publish machine data. HMIs, SCADA systems and dashboards can subscribe through suitable MQTT clients or integrations.
Does it replace a PLC or SCADA system?
No. SkarBroker moves messages between connected systems. PLCs continue to control machines, while HMIs and SCADA systems continue to visualize and supervise operations.
