Data Handling Instructions 5-15
Entering Parameters
Enter the following parameters when programming this instruction.
• Source is the program constant or element address. The file indicator
(#) is not required for an element address. When using either an SLC
5/03 (OS301 or higher), SLC 5/04 (OS401), or SLC 5/05 processor,
floating point and string values are supported.
• Destination is the destination starting address of the file you want to fill.
You must use the file indicator (#) in the address. When using either an
SLC 5/03 (OS301 or higher), SLC 5/04 (OS401), or SLC 5/05
processor, floating point and string values are supported.
• Length is the number of elements in the file you want filled.
– Maximum length is based on destination file type. If the destination
file type is 3 words per element (Timer or Counter), you can specify a
maximum length of 42. If the destination file type is 1 word per
element, you can specify a maximum length of 128 words.
The instruction will not write over a file boundary (such as between files N16
and N17) at the destination. An error is declared if a write is attempted over a
file boundary.
TIP
The maximum lengths are based on destination file
type.
TIP
All elements are filled from the source value (typically
a constant) into the specified destination file each
scan the rung is true. Elements are filled in ascending
order.
