ICredentialsProvider (ITF) ¶ INTERFACE ICredentialsProvider EXTENDS IGeneric -> IGeneric Methods: GetCredentials IsGetCredentialsFinished LoginFailed StartGetCredentials GetInterface , inherited from IGeneric Structure: GetCredentials (Method) IsGetCredentialsFinished (Method) LoginFailed (Method) StartGetCredentials (Method)
ICredentialsProvider.GetCredentials (METH) ¶ METHOD GetCredentials : UDINT Must return ERR_OK if called after a successfull <see cref=”IsGetCredentialsFinished”> InOut: Scope Name Type Return GetCredentials UDINT Input udiRequestId UDINT Output stUserName STRING stPassword STRING
ICredentialsProvider.IsGetCredentialsFinished (METH) ¶ METHOD IsGetCredentialsFinished : UDINT Will return ERR_OK if the request is finished, ERR_PENDING if it is not yet finished, ERR_DS_RETRYLOGIN if the login should be tried again, another error code in case of an error InOut: Scope Name Type Return IsGetCredentialsFinished UDINT Input udiRequestId UDINT
ICredentialsProvider.LoginFailed (METH) ¶ METHOD LoginFailed : UDINT Will be called when a login failed due to wrong credentials The behaviour of the datasource afterwards depends on the return value. In case of ERR_PENDING, the logincycle will be started again with a call to GetCredentials. In all other cases the driver will go to it’s error state. InOut: Scope Name Type Comment Return LoginFailed UDINT Input udiRequestId UDINT Output udiRetryWaitTime UDINT The time that is waited until the next try to login is started
ICredentialsProvider.StartGetCredentials (METH) ¶ METHOD StartGetCredentials : UDINT Will return an id of the question for credentials. This id can be used in the following calls to <see cref=”IsGetCredentialsFinished”/> InOut: Scope Name Type Comment Return StartGetCredentials UDINT Input pstDataSource POINTER TO STRING The name of the datasource Output udiErrorCode UDINT

IDataGroup.AddItem (METH) ¶ METHOD AddItem : UDINT InOut: Scope Name Type Return AddItem UDINT Input pstSymbol POINTER TO STRING
IDataGroup.Clear (METH) ¶ METHOD Clear : BOOL InOut: Scope Name Type Return Clear BOOL
IDataGroup.Release (METH) ¶ METHOD Release : UDINT InOut: Scope Name Type Return Release UDINT
