Manage Measurement Point parameters

Parameters control naming, units, filtering, precision, scaling, and type-specific behavior for data displayed in Charts. Manage them from the Edit Measurement Point modal.

See the full parameter catalog and advanced field descriptions in Parameters overview.

User Permissions

Guests cannot modify parameters. Roles that can edit a Measurement Point may manage parameters.

Interface overview​

Screenshot: Parameters management modal showing form on top and table below

Main areas:

  1. Measurement Point header
  2. Bulk actions toolbar (Copy / Insert)
  3. Parameter form (create or edit)
  4. Parameters table (filter, sort, paginate)

Create or edit a parameter​

  1. Fill required fields: Name, Value, Channel (if channel‑specific)
  2. (Optional) Add filters (validFrom, chartType, unitId, sensorTypeId, measId, eventTypeId, application)
  3. Click Add to create or Save (when editing)
  4. Confirm it appears or updates in the table
Saving vs. form state

Changes are only applied after clicking Add or Save. Leaving the form without those actions discards edits.

Insert multiple parameters (bulk paste)​

Use the Insert action to paste a JSON array of parameter objects:

  1. Click Insert
  2. Paste JSON
  3. Choose:
    • Add only new — keeps existing; adds non-duplicates
    • Overwrite — ⚠️ replaces all current parameters with pasted set ⚠️
  4. Confirm; new parameters appear at top

Avoid duplicates

The system detects duplicates (same name, channel, and filters). Use Overwrite for full replacement or Add only new to extend.

Duplicate detection​

If a pasted or created parameter matches an existing one, a duplicate alert appears and the new entry isn’t added. Adjust filters or rename as needed.

Unsaved changes prompt​

Leaving the parameters modal with unsaved edits triggers a confirmation dialog—save changes or discard them.

Copy all parameters​

Click Copy to place a JSON representation of all parameters on the clipboard (for backup or transfer to another Measurement Point).

Parameter precedence​

When multiple records share the same name and scope, the most recent valid (by validFromEpoch) applies to data points in charts and exports.
