A SCADA (Supervisory Control and Data Acquisition) gateway is a device or software component that acts as an intermediary between a SCADA system and other devices or networks. SCADA systems are used to monitor and control industrial processes and infrastructure, such as power plants, manufacturing facilities.
The purpose of a SCADA gateway is to enable communication and data exchange between the SCADA system and various field devices, such as programmable logic controllers (PLCs), sensors, actuators, and other control devices. The gateway serves as a bridge, allowing the SCADA system to gather data from the field devices and send control commands to them.
PDC Scada gateway is designed to unify and manage information from different IEDs in a simple and efficient way, and send it to local or remote SCADA systems, using protocols such as:
- DNP3 TCP (master/slave),
- DNP3 serial (master/slave),
- IEC 60870-5-104 (slave),
- IEC 60870-5-103 (master),
- IEC 60870-5-101 (master/slave),
- MODBUS TCP (master/slave),
- MODBUS RTU (master) and
- IEC 61850 (client)
