Scenario Detail(s)

Charge Point (SUT)	Central System (Tool)
[Remove connectivity between Charge Point and Central System.]; [EV Driver starts offline a transaction with a valid idTag.]; [Restore connectivity between Charge Point and Central System.]; 1. The Charge Point sends a StartTransaction.req	2. The Central System responds with a StartTransaction.conf
3. The Charge Point sends a StatusNotification.req	4. The Central System responds with a StatusNotification.conf
