• 0000H is stored at S(P). SFCSCOMR instruction, and the total number
of steps are stored at completion of comment readout.
Number of steps that have
read comments (N)
• 0000H is stored at S(P). SFCSCOMR instruction, and the total number
of steps that have actually read comments are stored.
Step No. • Active step No. that has read comment is stored.
Comment
• Comments that have been read are stored.
• Comment area is fixed by a maximum of 32 characters.
• In case the word length to be set for 1 comment

With S(P) .SFCSCOMR instruction, the points calculated by the following formula are occupied
from the device No. specified at
D1
.
(Points to be used for storing a comment) = 2 + 20
(number of comment to read (n2))
For
D1
, make sure to set device No. that can store the above points successively.
