Entering Parameters
• Source is the address of the word to be encoded. Only one bit of this word
should be on at any time. If more than one bit in the source is set, the
destination bits are set based on the least significant bit that is set. If a source of
zero is used, all of the destination bits are reset and the zero bit is set.
• Destination is the address that contains the bit encode information. Bits 4–15
of the destination are reset by the ENC instruction.
Updates to Arithmetic Status Bits
The arithmetic status bits are found in Word 0, bits 0–3 in the status file. After an
instruction is executed, the arithmetic status bits in the status file are updated:
With this Bit: The Controller:
S:0/0 Carry (C) always resets.
S:0/1 Overflow (V) sets if more than one bit in the source is set; otherwise reset. The math overflow bit (S:5/0) is not set.
S:0/2 Zero (Z) sets if destination value is zero.
S:0/3 Sign (S) always resets.

Copy File (COP) and 
Fill File (FLL) Instructions
The destination file type determines the number of words that an instruction
transfers. For example, if the destination file type is a counter and the source file
type is an integer, three integer words are transferred for each element in the
counter-type file.
After a COP or FLL instruction is executed, index register S:24 is cleared to zero.
Using COP
This instruction copies blocks of data from one location into another. It uses no
status bits. If you need an enable bit, program an output instruction (OTE) in
parallel using an internal bit as the output address. The following figure shows how
file instruction data is manipulated.

File to File
Entering Parameters
Enter the following parameters when programming this instruction:
• Source is the address of the file you want to copy. 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.
• Destination is the starting address where the instruction stores the copy. 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 to copy.
– For SLC processors, 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.

Note The maximum lengths apply when the source is of the same file type.
All elements are copied from the source file into the destination file each time the
instruction is executed. Elements are copied in ascending order.
If your destination file type is a timer, counter, or control file, be sure that the source
words corresponding to the status words of your destination file contains zeros.
Be sure that you accurately specify the starting address and length of the data block
you are copying. The instruction will not write over a file boundary (such as
between files N16 and N17) at the destination. An error occurs if a write is
attempted over a file boundary.
You can perform file shifts by specifying a source element address one or more
elements greater than the destination element address within the same file. This
shifts data to lower element addresses.

Using FLL
This instruction loads elements of a file with either a program constant or value
from an element address.
The instruction fills the words of a file with a source value. It uses no status bits. If
you need an enable bit, program a parallel output that uses a storage address. The
following figure shows how file instruction data is manipulated.

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.

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.

Move and Logical Instructions Overview
The following general information applies to move and logical instructions.

• Source is the address of the value on which the logical or move operation is to
be performed. The source can be a word address or a program constant, unless
otherwise described. If the
