SQUARE ROOT (SQR):

GRAY CODED DECIMAL(GCD):
This output instruction converts the Gray code Source to integer and places it in the Destination. On a True rung, this instruction sets the value of the Destination to the integer value corresponding to the Gray code Source. If the Gray code input is negative (high bit set), the destination is set to 32767 and the overflow flag is set. The GCD instruction only operates on Word operands.
MOVE:
When rung conditions preceding this instruction are true, the MOV instruction moves a copy of the source to the destination each scan. The original value remains intact and unchanged in its source location.
MASKED MOVE:
When rung conditions are true, the MVM instruction moves data from a source location to a destination, and allows portions of the destination data to be masked by a separate word. Data at the source address passes through the mask to the destination address. As long as the rung remains true, the instruction moves the same data each scan.
CLEAR:
When rung conditions are true, this output instruction sets all the bits in a word to zero. The destination must be a word address.
AND:

GRAY CODED DECIMAL(GCD):
This output instruction converts the Gray code Source to integer and places it in the Destination. On a True rung, this instruction sets the value of the Destination to the integer value corresponding to the Gray code Source. If the Gray code input is negative (high bit set), the destination is set to 32767 and the overflow flag is set. The GCD instruction only operates on Word operands.
MOVE / LOGICAL INSTRUCTION:
If You Want to Use This Instruction
Move the source value to the destination MOV
Move data from a source location to a
selected portion of the destination MVM
Perform an AND operation AND
Perform an inclusive OR operation OR
Perform an Exclusive Or operation XOR
Perform a NOT operation NOT
When rung conditions preceding this instruction are true, the MOV instruction moves a copy of the source to the destination each scan. The original value remains intact and unchanged in its source location.
MASKED MOVE:
When rung conditions are true, the MVM instruction moves data from a source location to a destination, and allows portions of the destination data to be masked by a separate word. Data at the source address passes through the mask to the destination address. As long as the rung remains true, the instruction moves the same data each scan.
CLEAR:
When rung conditions are true, this output instruction sets all the bits in a word to zero. The destination must be a word address.
AND:
When rung conditions are true, sources A and B of this output instruction are ANDed bit by bit and stored in the destination.
JUMP:
When the rung condition for this output instruction is true, the processor jumps forward or backward to the corresponding label instruction (LBL) and resumes program execution at the label. More than one JMP instruction can jump to the same label. Jumping forward to a label saves program scan time by omitting a program segment until needed. Jumping backward lets the controller execute program segments repeatedly.
JUMP TO SUBROUTINE:
When rung conditions are true for this output instruction, it causes the processor to jump to the targeted subroutine file. You can only jump to the first instruction in a subroutine. Each subroutine must have a unique file number (decimal, 3-255).
SUBROUTINE PAGE:
TO CREATE THE NEW SUBROUTINE PAGE:
PROGRAM FILES – RIGHT CLICK NEW
TEMPORARILY END (TND):
Use this instruction to progressively debug a program, or conditionally omit the balance of your current program file or subroutines.
MASTER CONTROL RESET (MCR):
An input instruction is programmed on the rung of the first MCR to control rung logic continuity. When the rung goes "false" all non-retentive outputs within the controlled zone are disabled. When the rung goes "true" all rungs are scanned according to their normal rung conditions (disregarding the zone control instruction).
DECODER(DCD):
When rung conditions are true, the DCD instruction decodes a 4-bit value (0-16) in the source word and turns on a bit in the destination word that corresponds to the decoded value. For example, if bits 0-3 of a source word are 0110, then bit 6 in the destination word is set. The table below provides full details.
ENCODER (ENC):
This output instruction searches the source from the lowest to the highest bit and looks for the first set bit. The corresponding bit position is written to the destination as an integer.
PROGRAM CONTROL:
If You Want to Use This Instruction
Jump forward/backward to a
corresponding label instruction JMP, LBL
Jump to a designated subroutine and return JSR, SBR, RET
Enable or inhibit a master control zone
in your ladder program MCR
Truncate program scan TND
When the rung condition for this output instruction is true, the processor jumps forward or backward to the corresponding label instruction (LBL) and resumes program execution at the label.

Jumping backward lets the controller execute program segments repeatedly.

ADVANCED MATH INSTRUCTION:
If You Want to: Use This Instruction:
Swap the low and high bytes
of a specified number of words SWP
Scale a value to a range determined
by creating a linear relationship SCP
Calculate the absolute value of a number ABS
Decoder functions DCD
Encoder function ENC
When rung conditions are true, the DCD instruction decodes a 4-bit value (0-16) in the source word and turns on a bit in the destination word that corresponds to the decoded value. For example, if bits 0-3 of a source word are 0110, then bit 6 in the destination word is set. The table below provides full details.
ENCODER (ENC):
This output instruction searches the source from the lowest to the highest bit and looks for the first set bit. The corresponding bit position is written to the destination as an integer.
SCALE WITH PARAMETER(SCL):
This output instruction consists of six parameters. Parameters may be integer, long, floating point (Floating point is only supported in the SLC 5/03, 5/04, and 5/05; not in the MicroLogix 1200 and 1500 processors.), or immediate data values or addresses containing values. The Input value is scaled to a range determined by creating a linear relationship between input min and max values and scaled min and max values. The scaled result is returned to the address indicated by the output parameter.
SWAP (SWP):
Use the swap instruction to swap the low and high bytes of a specified number of words in a bit, integer, ASCII, or string file. The instruction consists of two parameters, a source and a length.
ABSOLUTE VALUE (ABS):
This output instruction consists of two parameters, a source and a destination. When enabled it calculates the absolute value of the source and places the result in the destination.
Source can be a word address, an integer constant, floating point data element, or floating point constant.
