Recharge Method – OPC UA for Unattended Retail & Coffee Solutions

7.21.6 Recharge Method

The Recharge Method is recharging money to an account associated to the current UserId.

If the execution of the Method cannot be done due to some application logic, the Method should return an Uncertain StatusCode and provide details of the failure in the Status output Argument. When the Method returns an Uncertain StatusCode, the Method is considered to be failed.

If the Method returns successful, it does not indicate, that the recharge has been completed successful. Clients need to access the RechargeStatus Variable to get the information, if the recharge successfully finished.

The signature of this Method is specified below. Table 73 and Table 74 specify the Arguments and AddressSpace representation, respectively.
