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.

Industrial automation setups requiring high-performance processing utilize the CX1030-0112 basic CPU module as a central control unit within the Beckhoff Embedded PC system. This module features an Intel Pentium M processor running at 1.8 GHz, delivering considerable computing power for demanding PLC, NC PTP, or NC I motion control applications. Configured with a internal 16-bit ISA (PC/104) system bus, the module maintains robust communication capabilities with adjacent system expansion terminals.
The unit acts as the core controller, relying on compatible CX1100 power supply modules to interface with either E-bus or K-bus I/O terminal systems. Network communications are facilitated via two RJ45 ports connected through an internal switch, enabling simple daisy-chain networking topologies without external switches. To ensure operational stability under high thermal loads, the processor is fitted with an active cooling module consisting of a speed-controlled, double ball bearing fan cartridge that can be easily replaced in the field.
