8.4.6 FileSystemLoadingType

8.4.6.1 Overview

The FileSystemLoadingType enables software update based on an open file system. This enables the FileSystem based Loading option of 8.3.4.5.

It is illustrated in Figure 46 and formally defined in Table 85.

8.4.6.2 FileSystem

The FileSystem Object is of type FileDirectoryType as it is defined in OPC 10000-5. It provides access to a hierarchy of directories and files of the device. The structure can be read and written by the Client however the device can restrict this for specific folders or files.

8.4.6.3 GetUpdateBehavior Method

This Method can be used to check the specific update behavior for a set of files. The files are identified by the NodeId of their FileType instance in the FileSystem.

Signature

	GetUpdateBehavior(
	  [in]  0:NodeId[]		NodeIds,
	  [out] UpdateBehavior	UpdateBehavior);

Method Result Codes (defined in Call Service)

8.4.6.4 ValidateFiles Method

This Method can be used to check if the specified set of files are valid and complete for an installation. This should also include dependency checks if appropriate.

Note: In case of Direct-Loading or Cached-Loading these checks should be part of the transfer and this method shall not be supported since it is part of the file transfer (e.g., in CloseAndCommit).

Signature

	ValidateFiles(
	  [in] 0:NodeId[]		NodeIds,
	  [out] 0:Int32		ErrorCode,
	  [out] 0:LocalizedText	ErrorMessage);
