Data Manipulation and Math Instruction

Data Manipulation involves transfer of data and operation on data with math instruction, data conversion, data comparison, and logical operations.

Data Manipulation Instruction

Each data manipulation instruction requires two or more words of data memory for operation

Data file, word, and bits

Data Transfer Operation

Data transfer concept


1. MOV (Move)Moves the source value to destination

Source is the address of the data you want to move. The source can be a constant.Destination is the address that identifies where the data is to be moved.

MOVE/LOGICAL

2. MVM (Masked Move)Moves the source location to selected portion of the destination

Source is the address of the data you want to move.Mask is the address of the mask through which the instruction moves data. Destination is the address where the instruction moves the data.

MOVE/LOGICAL


Mask is the address of the mask through which the instruction moves data. The mask can also be a hexadecimal value. You can enter the value in binary, decimal, or hexadecimal. RSLogix 500Micro will make any necessary conversion and display the hexadecimal value.

The mask acts like a filter for the destination. The pattern of characters in the mask determines which bits will be passed from the source to the destination, and which bits will be masked. Only bits in the mask that are set (1) will pass data to the destination.

For example:If before the move, the destination address contains 0000000000000000and the bit values in the source word are - 1111000011110000and the bit setting in the mask address are - 0000000011111111after the move, the destination will contain - 0000000011110000


3. AND (And)Performs a bitwise AND operation

Sources A and B can be either word addresses or constants; however, both sources cannot be a constant. The Destination must be a word address.

MOVE/LOGICAL


4. OR (Or)Performs a bitwise OR operation

Sources A and B can be either word addresses or constants; however, both sources cannot be a constant. You can enter a constant or a word address for either Source parameter.The destination must be a word address.

MOVE/LOGICAL

5. XOR (Exculive Or)Performs a bitwise XOR operation

Sources A and B of the XOR instruction are Exclusive ORed bit by bit and stored in the destination. Sources A and B can be either word addresses or constants; however, both sources cannot be a constant.

MOVE/LOGICAL


6. NOT (Not)Performs a NOT operation

The source of the NOT instruction is NOTed bit by bit and stored in the destination.The source and destination must be word addresses

MOVE/LOGICAL


7. CLR (Clear)Sets all bits of a word to zero.

When rung conditions are true, this output instruction sets all the bits in a word to zero. The destination must be a word address.

MOVE/LOGICAL

Data Manipulation Application

Changing the preset value of a timer using the move (MOV) instuction


Moving data using file instruction


SLC 500 word and file address

(a) Adrress N7:30 is a word address that represents a single word: word number 30 in integer file 7

(b) Address #N7:30 represents the starting address of a group of conssecutive words in integer file 7. The length shown is eight words, which is determained by the instruction where the file address is used


1. COP (Copy)Example file copy instruction

FILE/MISK


2. FLL Example FLL instruction.

FILE/MISK

Data Transfer Application

Using the FFL instruction to change all the data in a file to zero

NEQ logic rung(Tests whether one values is not equal to a second value)


GRT logic rung(Tests whether one values is greater than a second value)


LES logic rung(Tests whether one values is less than a second value)


GEQ logic rung(Tests whether one values is greater than or equal to a second value)


LEQ logic rung(Tests whether one values is less than or equal to a second value)


LIM instruction where the low limit value is less then the high limit value(Tests whether one values is within the limit range of two other value)


LIM instruction where the low limit value is greater then the high limit value

(Tests whether one values is within the limit range of two other value)


Masked comparison for equal (MEQ) logic rung(Tests portion of two values to see whether they are equal. Compare 16-bit data of a source

address to 16-bit data at a reference address thrugh mask)
