Description
The CSMS is able to request the status of a transaction and to find out whether there are queued transaction-related messages, using the GetTransactionStatusRequest message.
Purpose
To verify if the Charging Station is able to correctly respond to a GetTransactionStatusRequest without a transactionId, while there is a message queued.
Prerequisite(s)
N/a
Before (Preparations)
Configuration State:
- SampledDataTxUpdatedMeasurands is <Configured transaction_updated_metervalues_measurands> SampledDataTxUpdatedInterval is <Configured transaction_updated_metervalues_interval> OfflineThreshold is <Configured RetryBackOffWaitMinimum_duration> + 60.0 RetryBackOffWaitMinimum is <Configured RetryBackOffWaitMinimum_duration> RetryBackOffRandomRange is 0
- Note: <Configured RetryBackOffWaitMinimum_duration> must be greater than <Configured Transaction MeterValues interval>
Memory State:
- N/a
Reusable State(s):
- State is EnergyTransferStarted
Main (Test scenario)
| Charging Station | CSMS |
|---|---|
| 1. The OCTT closes the WebSocket connection AND does not accept a reconnect. | |
| 2. The OCTT waits a number of seconds equal to <Configured RetryBackOffWaitMinimum_duration>, before accepting a reconnection attempt from the Charging Station. | |
| 4. The Charging Station responds with a GetTransactionStatusResponse | 3. The OCTT sends a GetTransactionStatusRequest; with transactionId omitted; Note: This step will be executed the moment the WebSocket connection is restored. |
| 5. The Charging Stations sends a TransactionEventRequest; Note(s):; - The Charging Station will empty its Transaction message queue. This will contain one or more TransactionEventRequest messages | 6. The OCTT responds with a TransactionEventResponse |
