For example, when the comment of
is "LineNo.1Start", it is stored in
and later as shown
below.

Caution
• To the device
, specify a device number for which comment is registered (written) in the PLC.
If comment is not registered (written) for the device
, "20H" (space) is stored in
and later for
the number of characters in the comment (16 half-width characters).
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 any comment is not registered (written) in the device
(error code: K6706)
• When the range of points used after
for comment exceeds the corresponding device range
(error code: K6706)
ON/OFF status
Contents of processing
M8091 = OFF
•
When the number of characters in the comment is odd, "00H" is stored in the high-order byte (8
bits) of the device storing the final character.
•
When the number of characters in the comment is even, "00H" is stored in the next device of the
device storing the final character.
M8091 = ON
•
When the number of characters in the comment is odd, the high-order byte (8 bits) of the device
storing the final character does not change.
•
When the number of characters in the comment is even, the next device of the device storing the
