The need and approach
An operational screen should answer a particular user’s question before adding charts. Maintenance needs fault context, management needs fair period comparisons and operators need current conditions.
Data flow
Source data → validation → time-series and event storage → role-based dashboard.
Last update, data quality, units and time zone remain visible. Trend lines do not conceal gaps. Filters and aggregations can be traced to their underlying records.
Illustrative workflow
A maintenance user opens a machine’s history from an active alarm. The screen shows the start of the alarm alongside connection status at the same time.
Questions for discovery
- Which roles will use the screen?
- Which decisions need current or historical data?
- When should a value be considered stale?
- Which periods should be compared?
- What should users see during an outage?
Limits and field conditions
A remote screen does not replace local safety functions or an operator. Connectivity and access conditions determine what is practical.
Common questions
Can existing equipment be used?
Suitability depends on the device interface, manufacturer documentation, access permission and a field test. Start by sharing model details and the signals that are available.
