Signals
What a device measures, one row per quantity. The scaling lives here because it is a property of the measurement — applied downstream, every consumer has to know it and one of them eventually will not.

The form
What is asked for when a record is created here. Required fields are marked; a choice drawn from a configuration list is one an administrator can extend without a release.
| Field | Type | Choices | Notes |
|---|---|---|---|
| Device required | Choice | Looked up from existing records | |
| Signal key required | Text | ||
| Name required | Text | ||
| Measures | Choice | temperature, pressure, vibration, current, voltage, power, energy, flow, level, humidity, speed, torque, count, position, ph, other | |
| Unit | Text | ||
| Scale factor | Number | ||
| Offset | Number | ||
| Deadband | Number | ||
| Normal minimum | Number | ||
| Normal maximum | Number | ||
| What it means here | Choice | none, recipe_parameter, oee_count, oee_state, spc_characteristic, condition_monitor | A temperature is a temperature until it is bound to a recipe parameter — at which point capturing it into a batch record becomes configuration rather than code. |
| Recipe parameter | Choice | Looked up from existing records | |
| Control chart | Choice | Looked up from existing records | |
| Retention (days) | Number | ||
| Active | Yes or no |
The rules that apply here
Everything on this screen obeys the platform rules rather than rules of its own. The ones worth knowing before you use it:
- Narrowing a list — search, conditions, sort, totals, export and saved views.
- What may be changed — the five grounds a record may not be edited on.
- Companies and business units — what the switcher above this list is doing to it.
- Creating a record — required fields, where choices come from, and how the number is allocated.
- Importing a spreadsheet — this screen accepts one, and it runs through the same rules as typing.
