IDriverTraceAddressInfoProvider.ReleaseTraceAddressInfoWriter (METH) ¶ METHOD ReleaseTraceAddressInfoWriter : SysTypes.RTS_IEC_RESULT Releases an ITraceAddressInfoWriter instance, that was previously returned by a call to method IDriverTraceAddressInfoProvider.CreateTraceAddressInfoWriter InOut: Scope Name Type Comment Return ReleaseTraceAddressInfoWriter SysTypes.RTS_IEC_RESULT The error code Input itfTraceAddressInfoWriter ITraceAddressInfoWriter

ETraceAddressFlags (ENUM) ¶ TYPE ETraceAddressFlags : This enumeration is similar to the enumeration <c>EAddressFlags</c> of library trace manager interfaces and defines the type of address info, that will be passed to CmpTraceMgr. Attributes: qualified_only InOut: Name Initial Comment Iec 16#1 The variable is defined in an IEC-Programm. IOConfig 16#2 The recorded value is a parameter in the CoDeSys configuration. AreaOffset 16#20 The location of the recorded value is described by an area number and an offset in this area. Prop 16#40 Corresponding to the automation platform enum value <c>AddressFlags.Property</c>, which cannot be used here, because “Property” is a reserved word.

ReusableRequestOperations (ENUM) ¶ TYPE ReusableRequestOperations : This enumeration represents operations on IDriverRequestReusable Attributes: qualified_only InOut: Name Comment Prepare The request will be prepared. This step is possible only once and is used for registering the list of items in the connected device or server. Read The next operation will be a read Write The next operation will be a write
