Procedures Section 3-2
(2) The Function Block Holding Area words are allocated in H512 to H1535.
These words cannot be specified in instruction operands in the user pro-
gram. These words can also not be specified in the internal variable’s AT
settings.
(3) Words H512 to H1535 are contained in the Holding Area, but the ad-
dresses set as non-retained will be cleared when the power is turned
OFF and ON again or when operation is started.
(4) To prevent overlapping of instance area addresses and addresses used
in the program, set H512 to H1535 (Function Block Holding Area words)
for the non-retained area and retained area. If there are not sufficient
words, use words in areas not used by the user program. If another area
is set, the addresses may overlap with addresses that are used in the
user program.
If the addresses in the function block instance areas overlap with any of
the addresses used in the user program, an error will occur when compil-
ing. This error will also occur when a program is downloaded, edited on-
line, or checked by the user.
If addresses are duplicated and an error occurs, either change the function
block instance areas or the addresses used in the user program.
