5) Accident Alarm

Provides real-time alarm and historical query printing functions for events. Alarm types include warnings, actions, operations, systems, telemetry limit exceedances, and remote signal displacements. Historical event queries can be categorized by time period, plant information, group information, type queries, or combinations of various methods.

6) Report Curves

Provides the function to query and print historical data in the form of reports and curves. Reports include daily, monthly, and annual reports, each edited flexibly and conveniently by report editors; historical data for any telemetry point can be reviewed in curve form.

7) Module Management

Mainly used to manage protectors, PLCs, and other intelligent communication modules. Functions include viewing the type and name of each module; viewing, modifying, and printing the settings of each module; viewing telemetry and remote signal data of each module; issuing commands for time synchronization, reset, etc.

8) Data Communication

The configuration of communication modules is related to on-site requirements, generally including protector communication modules, PLC communication modules, dispatch communication modules, reserved communication modules for other systems (such as water condition monitoring systems, fire alarm systems, etc.), and other intelligent communication modules (such as temperature inspection instruments, electric meters, excitation, speed regulator modules, etc.). Real-time communication status and data can be viewed through the message viewing window.
