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 to deliver reliable industrial computing in a space-saving form factor, the BECKHOFF C9900-F303 represents a rugged, high-performance Economy built-in Panel PC configuration. Engineered for mounting in control cabinets and consoles, this unit combines an industrial-grade 19-inch display with powerful processing capabilities to manage complex visualization and control tasks on the factory floor.
The core of this Panel PC is a 3.5-inch industrial motherboard paired with an Intel Celeron G3900TE processor and 4 GB of DDR4 RAM. For data storage and redundancy, the unit features an on-board SATA RAID 1 controller, a 320 GB 2.5-inch hard drive, and specialized slots supporting both hard disks/SSDs and CFast flash cards. Encased in a durable stainless steel housing with a flush-mounted front touch screen, this device offers IP65 ingress protection on the front side, making it highly resilient against liquid splashes, dust, and particulate contamination.
