What Is SCADA? Supervisory Control Without Replacing the PLC
SCADA sits above PLCs and RTUs: it acquires field data, alarms operators, and issues supervisory commands across plants and remote assets—without replacing local deterministic control.



Designed for cost-effective, continuous asset protection, the Bently Nevada 2300/20-CN vibration monitor provides reliable status assessment for critical and general-purpose rotating machinery. This dual-channel monitoring system processes input signals from proximity probes, accelerometers, or velocity transducers to evaluate overall vibration levels, axial position, or rotational speed. Implementing the 2300/20-CN within a facility's predictive maintenance framework enables operators to identify mechanical faults, unbalance, and structural misalignments prior to catastrophic equipment failure. The module features integrated Ethernet capabilities for Modbus TCP/IP communication and supports seamless connection to Bently Nevada's System 1 software for detailed asset condition monitoring and diagnostics.
