Common Communication Protocols in SCADA Systems

In SCADA systems, various communication protocols are commonly used to facilitate data transfer and control functions. The primary communication protocols in SCADA systems include:

  • Modbus
  • DNP3 (Distributed Network Protocol)
  • IEC 60870
  • OPC (OLE for Process Control)

These communication protocols play a crucial role in enabling seamless communication between various components of SCADA systems, such as RTUs (Remote Terminal Units) and PLCs (Programmable Logic Controllers).

Overall, understanding and leveraging these common communication protocols is essential for ensuring efficient and reliable operation of SCADA systems.
