variable_attribute

OCPP 2.1 VariableAttribute data type (schema VariableAttributeType).

to_json/decoder map to/from its OCPP-J JSON object; new (when present) builds a value from the required fields only.

Types

VariableAttribute

</>

Attribute data of a variable.

Field	Type	Req	Description
`constant`	`Bool`	—	If true, value that will never be changed by the Charging Station at runtime. Default when omitted is false.
`custom_data`	`CustomData`	—
`mutability`	`Mutability`	—
`persistent`	`Bool`	—	If true, value will be persistent across system reboots or power down. Default when omitted is false.
`type_`	`Attribute`	—
`value`	`String`	—	Value of the attribute. May only be omitted when mutability is set to ‘WriteOnly’. The Configuration Variable `ReportingValueSize` can be used to limit GetVariableResult.attributeValue, VariableAttribute.value and EventData.actualValue. The max size of these values will always remain equal. (max 2500 chars)
