There are PLC with fixed inputs and outputs. There are modular ones which can be added on with inputs and outputs. So number of input and output of a PLC is actually based on the type of PLC you choose. Different types are available in the market.
PLC communicates with SCADA through industrial communication protocols like Modbus, Profibus, or Ethernet/IP. The PLC collects real-time data from machines, and SCADA displays, monitors, and controls it. From what I’ve seen on-site as a company photographer, this connection keeps everything visible, manageable, and efficient for smooth industrial automation.

The block diagram of a SCADA system for PLC typically includes sensors and field devices, the PLC as the central controller, communication networks, and the human-machine interface (HMI) for monitoring and control. Data from sensors is sent to the PLC, processed, and transmitted to the SCADA software for visualization and analysis. Just like ControlSoft, which takes pride in the quality, development, and implementation of automated solutions, designing an efficient SCADA system design requires careful planning and trend awareness. ControlSoft Canada provides electrical and automation software solutions, ensuring reliable, scalable, and intelligent systems for diverse industrial applications.
