DNP3 HMI

A DNP3 HMI (Human Machine Interface) is the interface between DNP3 protocol devices and the end-user of a monitoring system. The DNP3 HMI enables a network operator to communicate with DNP3 devices by mediating the Distributed Network Protocol messages into a format that is readable by humans.

A DNP3 HMI Serves as the SCADA Monitoring Master
A DNP3 HMI can also be referred to as a “master station” or “DNP3 master”. Without a DNP3 HMI, operators are unable to work with the data collected by DNP3 IED’s and other devices within a SCADA operation. The DNP3 HMI provides protocol mediation, which allows the operator to interpret the alarms forwarded by RTU’s or Remote Terminal Units).

These network alarms that are collected by the remotes are displayed within the DNP3 HMI browser. This is a window displaying a comprehensive list of all standing alarms. The network operator can utilize the DNP3 HMI to manage these alarms, sending out technicians to service SCADA system components as needed.

DNP3 HMI Provides Important Historical Trend Reports
Processing data is one of the key functions of a DNP3 HMI. After analyzing data gathered from IED’s and other inputs within the SCADA operation, the DNP3 HMI can generate reports for the network operator. These reports can flag potential problems by summarizing the historical logs of alarm activity.

An advanced DNP3 HMI will often utilize a graphical user interface for the graphical display of alarms. This will generally include images of the entire SCADA system that can be scaled down to individual system components. This allows operators to use the DNP3 HMI to visualize the network as a whole when distributing technicians.

Deploy an Advanced DNP3 HMI to Monitor Your SCADA Operations
Your DNP3 HMI is of critical importance to your network reliability. Deploy only the most advanced technologies to monitor your SCADA operations. This will increase your revenues while reducing your customer churn.
