IDataServer6.GetAddress (METH) ¶ METHOD GetAddress : UDINT Determines the address info of an item. InOut: Scope Name Type Comment Return GetAddress UDINT Input pstSymbol POINTER TO STRING The fully qualified path to the item, e.g. ‘Remote_Device.Application.PLC_PRG.iSchlurpsknurps’ Output address PlcAddressInfoUnion
IDataSourceDriver.StartShutdown (METH) ¶ METHOD StartShutdown : UDINT InOut: Scope Name Type Return StartShutdown UDINT
IDataSourceDriver.State (PROP) ¶ PROPERTY State : DataSourceState
IDataSourceDriver.UpdateRequest (METH) ¶ METHOD UpdateRequest : UDINT This method will be called after a request has been sent to check, whether an answer has arrived.
