Parameters
Whether a Parameter's value is a plain scalar or an entity reference.
Set by the platform and read-only. It determines how a parameter's value is
interpreted when a setpoint is assigned to it inside a
Workflow.
Attributes:
| Name | Type | Description |
|---|---|---|
NORMAL |
str
|
A "normal" parameter whose value is a plain scalar (e.g. a number or text), such as Temperature or Spin Speed. |
SPECIAL |
str
|
A "special" parameter whose value references another entity (e.g. Equipment, a Consumable, or a Template). The setpoint value is that entity's ID rather than a plain scalar. |
Bases: BaseResource
The definition of a single experimental condition or input variable.
A Parameter (ID format PRM...) names an "indirect variable" such as
Temperature, Spin Speed, or Instrument. The Parameter itself only defines the
variable; its actual value and unit are fixed to a setpoint later, inside a
Workflow. Parameters are the building
blocks of Parameter Groups
(ParameterGroup) and form the
parameter side of Data Templates
(DataTemplate).
Manage parameters through
ParameterCollection
(client.parameters).
