Data Manipulation and Math Instruction
Lino Hugun Saputra (23315309) INSTITUT TEKNOLOGI BANDUNG
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.
1. Data Transfer Operation
2. Data Compare Instructions
3. Math Instructions
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Transfer Operation
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
Data Manipulation Application
Moving data using file instruction
Data Manipulation Application
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
Data Transfer Operation
1. COP (Copy)Example file copy instruction
FILE/MISK
Data Transfer Operation
2. FLL Example FLL instruction.
FILE/MISK
Data Transfer Application
Using the FFL instruction to change all the data in a file to zero
