8.8.4.2 Files Manager
FilesManager := { "(" pakbus-address "," name-prefix "," number-files ")" }.
pakbus-address := number. ; 0 < number < 4095
name-prefix := string.
number_files := number. ; 0 <= number < 10000000
This setting specifies the numbers of files of a designated type that are saved
when received from a specified node. There can be up to four such settings. The
files are renamed by using the specified file name optionally altered by a serial
number inserted before the file type. This serial number is used by the datalogger
to know which file to delete after the serial number exceeds the specified number
of files to retain. If the number of files is 0, the serial number is not inserted. A
special node PakBus address of 3210 can be used if the files are sent with FTP
protocol, or 3211 if the files are written with CRBasic.
Note This setting will operate only on a file whose name is not a null
string.
Example:
(129,CPU:NorthWest.JPG,2)
(130,CRD:SouthEast.JPG,20)
(130,CPU:Message.TXT,0)
In the example above, *.JPG files from node 129 are named
CPU:NorthWestnnn.JPG and two files are retained . The nnn serial number
starts at 1 and will advance beyond nine digits. In this example, all *.TXT files
from node 130 are stored with the name CPU:Message.Txt, with no serial number
inserted.
