• In linking, "00H" indicating the end of a character string specified in
specified in
S
When a character string is linked, "00H" is automatically added at the end.
- When the number of characters after linking is odd, "00H" is stored in the high-order byte of a device
storing the last character.
- When the number of characters after linking is even, "0000H" is stored in next device of a device storing
the last character.
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 .

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
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 a same device is specified by

• When "00H" is not set within the corresponding device range after a device specified by
