Cautions
• When directly specifying a character string, up to 32 characters can be specified (input).
However, this limitation in the number of characters is not applied when a word device is specified in or
.
• When the values in both and start from "00H" (that is, when the number of characters is “0”), "0000H"
is stored in .
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 the number of devices after a device number specified by is smaller than the number of devices
required to store all linked character strings (that is, when “00H” cannot be stored after all character strings and the
last character) (error code: K6706)
• When the same device is specified in , and as a device for storing a character string (error
code: K6706)
• When “00H” is not set within the corresponding device range after the device specified by or (error
code: K6706)
Program example
In the program example shown below, a character string stored in D10 to D12 (abcde) is linked to the character string
“ABCD”, and the result is stored to D100 and later when X000 turns ON.
