7: The number of characters for 1 comment at the comment range setting is set with GX
Developer.
For further details, refer to the manual of GX Developer.
With S(P) .SFCTCOMR 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.
