File_RW Toolbox: Function Blocks
MotionWorks IEC61131-3 Toolboxes: 2013-09-13 213
Notes
• Don't forget to include the ProConOS firmware library in the project. It is required for this function
block.
• The filename must conform to 8.3 format, but is not case sensitive.
• Any separator can be specified provided it is an ASCII byte, and will not be confused with the actual
data.
• Header rows are not required to contain the same number of separators as the data content.
(Separators are not checked in the header rows.)
• It takes 6 scans per processing of each BufferSize of data. If a file has 20480 bytes, and the BufferSize
is 2048, and the function block is placed in a 100mSec scan, then the total time to process the file will
be 60 scans, or 6 seconds. (20480/2048 * 6 * 100) = 6000 mSec.
