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.

Integrating remote digital outputs into DeviceNet control networks is highly efficient using the Omron DRT2-ROS16 remote I/O terminal. Designed as a DeviceNet Smart Slave, this module features 16 isolated relay outputs to handle switching tasks across diverse industrial machinery. The terminal utilizes replaceable DRTA-NY5W-K relays, facilitating simplified maintenance and minimizing downtime during field servicing. Built with built-in diagnostic and monitoring functions, it helps engineers track module operational status and plan preventative maintenance schedules directly through the network.
