Data Type
BOOLEAN
Objects
File
Description
This property of the type BOOLEAN indicates whether file
data may be changed by a BACnet-AtomicWriteFile service
(FALSE) or not (TRUE).
6.66 Record_Count
Data Type
Unsigned
Objects
File
Description
This property, of the type Unsigned, indicates the size of the
file data in records. The Record_Count property may be pre-
sent only if File_Access_Type is RECORD_ACCESS. If the
number of records can be changed by writing to the file,
then this property is writable.
Writing to the Record_Count property with a value less than
the current size of the file truncates the file at the specified
position. Writing a Record_Count of 0 deletes all of the file
data but not the File object itself. Writing to the Re-
cord_Count property with a value greater than the current
size of the file expands the size of the file, but the value of
the new octets of the file are determined locally.
