Instance Specifications
Section 2-3
Function Block Holding Area (H512 to H1535)
The default allocation of Function Block Holding Area words set as retained
and non-retained words is H512 to H1535. These words are different to the
standard Holding Area used for programs (H000 to H511), and are used only
for the function block instance area (internally allocated variable area).
• These words cannot be specified in AT settings for internal variables.
• These words cannot be specified as instruction operands.
• These words are displayed in red if they are input when a function
block is not being created.
• Although the words can be input when creating a function block, an
error will occur when the program is checked.
• If this area is specified as non-retained, turn the power ON/OFF or clear
the area without retaining the values when starting operation.
Note To prevent overlapping of instance area addresses with 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.
