Which is the comparison instruction used in PLC?
Use the MEQ instruction to compare data at a source address with data at a compare address. The Use of this instruction allows portions of the data to be masked by a separate word. Source is the address of the value you want to compare.
Which PLC instruction can do the work of two comparison instructions in a single instruction?
The EQU, also known as the Equal, instruction is used to compare two values.
What is bit logic in PLC?
Bits are the basic building blocks that we use to program programmable logic controllers. The three ways to view bits (Discrete, Number, and Position) will help users to understand the different ways to program.
What are data compare instructions?
Data comparison instructions compare two source operands. The most frequently used data comparison instructions use the result to determine the next instruction to be executed. They also serve as sequence control instructions. All of these instruction set or clear the low order bit of the destination register.
What are data compare instructions used for?
What are data compare instructions used for? Data compare instructions compare data stored in two or more words (registers) and make decisions based on the program instructions.
Which is the data compare instruction?
What is involved in a data compare instruction?
Which is a data compare instruction?
Data Comparison Instructions. Integer branch instructions compare two integers and branch based on the result. Integer compare instructions compare integers. Floating-point compare instructions compare floating-point numbers.
What is a bit level instruction?
Bit-level parallelism is a form of parallel computing based on increasing processor word size. The processor must first add the 8 lower-order bits from each integer, then add the 8 higher-order bits, requiring two instructions to complete a single operation.
