ISafetyIoServices (ITF) ¶ INTERFACE ISafetyIoServices EXTENDS __SYSTEM.IQueryInterface This interface defines communication methods used to exchange module-related service requests with the Safety runtime-system. Methods: Receive Send Structure: Receive (Method) Send (Method)

ISafetyIoServices.Send (METH) ¶ METHOD Send : SafetyIoServicesResult This method sends io-service-data to the IoServices. InOut: Scope Name Type Comment Return Send SafetyIoServicesResult SISR_OK - if data was sent successfully; SISR_PENDING - if data has not been sent yet; SISR_FAILED - if an error occurred. Input udiModuleId UDINT The id of the module to send io-service-data for. uiProtocolTypeId UINT The id of the protocol type. pbyData POINTER TO BYTE Pointer to the io-service-data. udiDataSize UDINT Size of the io-service-data to send.

Unions ¶ This library contains one Union-definition: ISafetyIoServices_Converter It is used to convert a memory address (aka pointer) to a typed reference. It’s a common trick to keep the compiler relaxed when converting between types without having a cast-operator. ISafetyIoServices_Converter (Union)

ISafetyIoServices_Converter (UNION) ¶ TYPE ISafetyIoServices_Converter : UNION Helps to ‘convert’ a POINTER/__XWORD into a reference of type ISafetyIoServices without generating warning/errors in the compiler. This is needed when reading and writing the instance to/from Parameters. Use instead of not-available type-casts. how to use Create a variable of this union-type. Write your memory address / pointer to the val -member of the variable. Get your typed reference to the interface ISafetyIoServices from the itf -member of the variable. InOut: Name Type Comment itf ISafetyIoServices typed access val __XWORD memory address
