14. FILE ACCESS SERVICES
|
||||
|
||||
This clause defines the set of services used to access and
|
||||
manipulate files contained in BACnet devices. The concept of files
|
||||
is used here as a network-visible representation for a collection
|
||||
of octets of arbitrary length and meaning. This is an abstract
|
||||
concept only and does not imply the use of disk, tape or other
|
||||
mass storage devices in the server devices. These services may
|
||||
be used to access vendor-defined files as well as specific
|
||||
files defined in the BACnet protocol standard.
|
||||
Every file that is accessible by File Access Services shall
|
||||
have a corresponding File object in the BACnet device. This File
|
||||
object is used to identify the particular file by name. In addition,
|
||||
the File object provides access to "header information," such
|
||||
as the file's total size, creation date, and type. File Access
|
||||
Services may model files in two ways: as a continuous stream of
|
||||
octets or as a contiguous sequence of numbered records.
|
||||
The File Access Services provide atomic read and write operations.
|
||||
In this context "atomic" means that during the execution
|
||||
of a read or write operation, no other AtomicReadFile or
|
||||
AtomicWriteFile operations are allowed for the same file.
|
||||
Synchronization of these services with internal operations
|
||||
of the BACnet device is a local matter and is not defined by this
|
||||
standard.
|
||||
|
||||
14.1 AtomicReadFile Service
|
||||
|
||||
14.1.5 Service Procedure
|
||||
|
||||
The responding BACnet-user shall first verify the validity
|
||||
of the 'File Identifier' parameter and return a 'Result(-)' response
|
||||
with the appropriate error class and code if the File object
|
||||
is unknown, if there is currently another AtomicReadFile or
|
||||
AtomicWriteFile service in progress, or if the File object is
|
||||
currently inaccessible for another reason. If the 'File Start
|
||||
Position' parameter or the 'File Start Record' parameter is
|
||||
either less than 0 or exceeds the actual file size, then the appropriate
|
||||
error is returned in a 'Result(-)' response. If not, then the
|
||||
responding BACnet-user shall read the number of octets specified by
|
||||
'Requested Octet Count' or the number of records specified by
|
||||
'Requested Record Count'. If the number of remaining octets or
|
||||
records is less than the requested amount, then the length of
|
||||
the 'File Data' returned or 'Returned Record Count' shall indicate
|
||||
the actual number read. If the returned response contains the
|
||||
last octet or record of the file, then the 'End Of File' parameter
|
||||
shall be TRUE, otherwise FALSE.
