Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is
stored in D8067.
• When “00H” is not set within the corresponding device range after a device specified by (error code:
K6706)
• When “n” exceeds the number of characters specified by (error code: K6706)
• When the number of devices after a device number specified by is smaller than the number of
devices required to store extracted “n” characters (that is, when “00H” cannot be stored after all character
strings and the last character) (error code: K6706)
• When “n” is a negative value (error code: K6706)
Program example
In the program example shown below, 4 characters are extracted from the right end of the character string
data stored in R0 and later, and stored to D0 and later when X000 turns ON.
