DrvSafetyIoServices_Shm3S ¶ Constants Function Blocks SafetyIoServices (FunctionBlock) ISafetyIoServices Receive (Method) Send (Method) Structs SafetyIoServiceDiagnostics_Shm3S (Struct)

Constants ¶ All the three Global_Constants we have are for internal use only:

Function Blocks ¶ Currently there is only one FunctionBlock: SafetyIoServices (FunctionBlock) ISafetyIoServices Receive (Method) Send (Method)

SafetyIoServices (FB) ¶ FUNCTION_BLOCK SafetyIoServices IMPLEMENTS SafetyIoServicesItfs.ISafetyIoServices SafetyIoServices_Shm3S reads and writes F-Device-data to the SharedMemory (created by SRTS) and implements ISafetyIoServices this way.

IDatasourcesMgr.ReleaseData (METH) ¶ METHOD ReleaseData : SysTypes.RTS_IEC_RESULT Deactivates the item of the given instance path from monitoring. Note The items are reference counted so each call to IDatasourcesMgr.UseData or IDatasourcesMgr3.UseDataExpanding requires a matching call to ReleaseData InOut: Scope Name Type Comment Return ReleaseData SysTypes.RTS_IEC_RESULT Returns a runtime system error code (see CmpErrors.library) or one of Errors Input pstSymbol POINTER TO STRING The symbolic name of the variable to activate. Here the name of the variable on the local PLC/HMI is expected.

IDatasourcesMgr.SetCredentialsProvider (METH) ¶ METHOD SetCredentialsProvider : SysTypes.RTS_IEC_RESULT Assigns the given credentials provider object to all datasources. InOut: Scope Name Type Comment Return SetCredentialsProvider SysTypes.RTS_IEC_RESULT An error code representing the result of the operation Input provider ICredentialsProvider The object to assign

IDatasourcesMgr.UseData (METH) ¶ METHOD UseData : SysTypes.RTS_IEC_RESULT Activates the item of the given instance path for monitoring. Note The items are reference counted so each call to IDatasourcesMgr.UseData requires a matching call to IDatasourcesMgr.ReleaseData Note Usually items are monitored in total. If you want to expand the items (to prevent problems with different alignment etc.) then consider using the method IDatasourcesMgr3.UseDataExpanding instead. InOut: Scope Name Type Comment Return UseData SysTypes.RTS_IEC_RESULT Returns a runtime system error code (see CmpErrors.library) or one of Errors Input pstSymbol POINTER TO STRING The symbolic name of the variable to activate. Here the name of the variable on the local PLC/HMI is expected.

IDatasourcesMgr.WriteItemsSync (METH) ¶ METHOD WriteItemsSync : SysTypes.RTS_IEC_RESULT Writes the given list of items synchronously. Important Please remark that the operation might take quite some time in case many items are contained within the list. For this time, the call is blocking! InOut: Scope Name Type Comment Return WriteItemsSync SysTypes.RTS_IEC_RESULT Input items IDataItemList The list of items that have to be written

IDatasourcesMgr2 (ITF) ¶ INTERFACE IDatasourcesMgr2 EXTENDS IDatasourcesMgr Extension of IDatasourcesMgr supporting persistant item lists for preregistering lists of variables within connected devices. Properties: PersistantItemListCount Methods: AddNotificationClient CreatePersistantItemList DeletePersistantItemList GetPersistantItemList Lock RemoveNotificationClient Unlock ActionRecordDelete , inherited from IDatasourcesMgr ActionRecordReplay , inherited from IDatasourcesMgr ActionRecordingGetResult , inherited from IDatasourcesMgr ActionRecordingStart , inherited from IDatasourcesMgr AllItemsOk , inherited from IDatasourcesMgr BeginDataConfiguration , inherited from IDatasourcesMgr CreateItemList , inherited from IDatasourcesMgr DeleteItemList , inherited from IDatasourcesMgr EndDataConfiguration , inherited from IDatasourcesMgr GetDatasource , inherited from IDatasourcesMgr GetItemInfo , inherited from IDatasourcesMgr ReadItemsSync , inherited from IDatasourcesMgr ReleaseData , inherited from IDatasourcesMgr SetCredentialsProvider , inherited from IDatasourcesMgr UseData , inherited from IDatasourcesMgr WriteItemsSync , inherited from IDatasourcesMgr Structure: AddNotificationClient (Method) CreatePersistantItemList (Method) DeletePersistantItemList (Method) GetPersistantItemList (Method) Lock (Method) PersistantItemListCount (Property) RemoveNotificationClient (Method) Unlock (Method)

IDatasourcesMgr2.AddNotificationClient (METH) ¶ METHOD AddNotificationClient : SysTypes.RTS_IEC_RESULT This method can be used to register an implementation of INotificationClient that will be notified about operations of the datasources. Note Please remark that the number of notification clients might be limited so at least if registering several clients the return value should be evaluated. Note The registered object can be removed using IDatasourcesMgr2.RemoveNotificationClient InOut: Scope Name Type Comment Return AddNotificationClient SysTypes.RTS_IEC_RESULT An error code that signals whether the registration was successful. Input client INotificationClient The object that will be notified about operations of the datasources.
