PLC (Programmable Logic Controller) and SCADA (Supervisory Control And Data Acquisition)
Systems:
Function and Purpose:
PLC: PLCs are primarily used for control and monitoring purposes. They handle real-time control of machinery, processes, and equipment.
SCADA: SCADA systems, on the other hand, focus on visualization and operator interface. They collect data from various facilities (even distant ones) and allow operators to supervise control operations.
