FileRead

FileRead(<area>, "<path>")
The FileRead() function reads the contents of a text file <path> from the <area> area and
returns it as a character string.
For the <path> argument, absolute paths are permitted in the NCU/PCU/RTS areas and
relative paths in the ARC/RTS areas.
The use of environment system variables and package variables is possible and permitted.
The following values are permitted for <area>:
● NCU - for the text file on the file system of the NCU/PPU.
Example: Up.File = FileRead(NCU, "/siemens/versions.xml").
● PCU - for the text file on the hard disk of the PCU 50.
The path must start with the drive letter, e.g. ""D:\"" or ""D$\"".
Example: Up.File = FileRead(PCU, "C:\Users\File.txt")
● ARC - for the text file in the archive image.
The path must start with NC\, MMC\, PLC\, CP\ or DRV\.
Example: Up.File = FileRead(ARC, "NC\CST.DIR\Test.SPF")
● RTS - for the text file on the RunTimeSystem (NCU/PPU, PCU,PC) on which the package
is executed.
Examples:
Up.File = FileRead(RTS,"MyText.txt") ;reads the file next to the package.
Up.File = FileRead(RTS,"%UP_PACK%/MyText.txt") ;path specification with
environment system variables under Windows; reads the file next to the package.
Up.File = FileRead(RTS,"$UP_PACK/MyText.txt") ;path specification with
environment system variables under Linux; reads the file next to the package.
Up.File = FileRead(RTS,"$(Up.Pfad)/MyText.txt") ;path specification via
script variable.
Up.File = FileRead(RTS,"$(Up.$Pack.Dir)/MyText.txt") ;path specification
via system variable.
