Units

Maintain the list of measurement units used across tasks, thresholds, and products.

Required role

Mapper or Admin.

Overview

A unit is a measurement unit (°C, bar, litre, hour, metre-per-second) that numeric fields attach to. Units feed:

  • Tasks — every numeric field references a unit.
  • Thresholds — every threshold references a unit.
  • Products — the unit quantities are recorded in (ml, g, l, pcs).

Without the right units in your catalogue, you can't configure tasks or thresholds accurately.

Open the page

Configuration → Asset Setup → Units.

Columns:

Column Meaning
Name Display name.
Symbol Short symbol used in tables and forms ("°C", "bar", "l").
Type Temperature / Pressure / Flow / Volume / Mass / Length / Time / Count / Other.
Conversion factor Optional — relative to the canonical unit of that type.
Active On / off toggle.

Create a unit

  1. New unit.

  2. Fill in:

    Field Notes
    Name Descriptive — "Celsius", "Bar absolute".
    Symbol Short display form — "°C", "bar".
    Type Pick from the list; determines which conversion factor is meaningful.
    Conversion factor Optional. If you have both bar and psi, store the conversion (1 bar = 14.504 psi).
    Description Optional internal notes.

  3. Save.

Typical starter catalogue

For most plants:

Name Symbol Type
Celsius °C Temperature
Bar bar Pressure
Ampere A Current
Volt V Voltage
Millilitre ml Volume
Litre l Volume
Gram g Mass
Kilogram kg Mass
Hour h Time
Minute min Time
Megohm MΩ Electrical resistance

Add industry-specific units (e.g. rpm, psi, kPa, NTU, °F) only if your team actually uses them.

Conversions

If you keep multiple units for the same type (bar and psi for pressure, °C and °F for temperature), the conversion factor lets reports aggregate across both.

For bar (canonical) and psi, the factor on psi would be 0.0689476 (1 psi = 0.069 bar).

If your whole plant standardises on one unit per type, you can ignore conversions.

Edit, deactivate, delete

Same pattern as other master data. Deactivate retired units; delete only mistakes.

Can't delete a referenced unit

The system blocks deleting a unit that's referenced by any task, threshold, or product. Unlink or reassign first.

Things to watch for

Don't use the symbol as the name

"°C" is the symbol; "Celsius" is the name. Name → displayed in lists. Symbol → displayed in forms next to numeric fields. Both matter.

One canonical per type

Pick one canonical unit per type (bar for pressure, °C for temperature, litres for volume) and try to use it everywhere. Mixing is technically possible via conversions but operationally confusing.
