Datapoint Overrides
Up to 17 overrides can be specified for any datapoint. Each override has a priority and value, where the priority is a value between 1 and 17, and the value is a datapoint value conforming to the type specification for the datapoint, or the value is *null* if an override is not active for the level.
Priority 1 is the highest priority, and priority 17 is the lowest. The highest active priority (i.e. active state and non-null value) override value is sent to a datapoint when the highest priority active override value is changed, or a higher priority override value is made active. If no override values are active, the default value is sent to the datapoint. The array of 17 override values is called the priority array.
To set and update Override states and values, refer to Datapoint Override State and Datapoint Override Value.
See also Normal Value, for information on overrides and normal values.
URI Definition
Method | URI and Fields |
GET | /iap/devs/{id}/if/{block}/{block_index}/{datapoint_name}/overrides |
Returns the priority array with priorities and override values for the specified datapoints. If multiple datapoints are specified, a separate priority array is returned for each. Any values that are not active are returned as null. The datapoint path element uses the datapoint instance name. The block path element uses the block XIFname. Query Parmeters
Success responseCollections with the priority array with priorities and override values for the specified datapoints. Exampleshttps://localhost/iap/devs/*/if/*/*/nvoEPpos/overrides
