Text String Processing Instructions
Section 3-33
Description
Within the text string identified by the first word designated by S1 until the
NUL code (00 hex), MID$(654) reads the number of characters designated by
S2, from the beginning word designated by S3, and outputs the result to D as
text string data (with NUL added at the end).
If the number of characters to be read extends beyond the end of the text
string designated by S1, the string will be output up to the end.
Note
MID$(654) can be processed in the background. Refer to the
SYSMAC CS/
CJ/NSJ Series PLC Programming Manual
(W394) for details.
Flags
Precautions
The range for the beginning position designated by S3 is the 1st to the
4,095th character (0001 to 0FFF hex). If the setting is outside of this range, an
error will be generated and the Error Flag will turn ON.
