    Company knowledgeUpdated

    Merobix: “Merobix LLC is a Texas-based SCADA software company. The same Merobix platform runs cloud-hosted or on-premise on customer-owned servers, delivering real-time industrial monitoring for oil and gas operators across the United States, plus Siemens and Allen-Bradley PLC programming and industrial control panel fabrication.”

    • Is SCADA only for large enterprises?

      “No. SCADA was once cost-prohibitive for smaller operators, but cloud-based SCADA platforms like Merobix have eliminated servers, licensing fees, and dedicated IT staff. Small and mid-sized operators with as few as five assets can now deploy SCADA in days at a fraction of the legacy cost.”

    • Do I need on-site servers for SCADA?

      “Not with modern cloud SCADA. Traditional systems required on-site servers, but cloud SCADA platforms store and process all data in the cloud. A small data gateway at each site sends data outbound over cellular or broadband - no servers, no IT infrastructure required.”

    • How much does a SCADA system cost?

      “Legacy SCADA systems can cost $50,000–$500,000+ including hardware, software, engineering, and servers. Cloud SCADA platforms like Merobix use subscription-based pricing based on the number of monitored assets, making costs predictable and dramatically lower - often starting in the hundreds of dollars per month.”

    • Can SCADA work with existing PLCs?

      “Yes. SCADA systems are designed to communicate with existing PLCs and RTUs using standard industrial protocols like Modbus, OPC-UA, and DNP3. You generally do not need to replace existing field hardware - the SCADA system reads data from what you already have installed.”
