Multiplication of two operands using MUL instruction in the PLC.
Application:-Explain MUL instruction in the PLC. Write PLC program for
explanation using ladder diagram language.
Components:-Programmable
logic controller, HMI panel, Ethernet cable, 24 V DC power source.
Diagram:-
Explanation:-
The MUL instruction is used for the multiplication of
two values for any data records. For example, we want a multiplication of two
values. We have taken HMI for entering data, here we have taken value 1 and
value 2 are the data fields and result data field will show the result of the
instruction.
Once the instruction is executed result will be
displayed in the result output field.
PLC
program:-
Write the ladder program for MUL instruction using ladder diagram language. Here for ladder logic, we can use any supported PLC system like S7-1200, S7-1500, or any other PLC which can support this instruction. In our application, we have used S7-1200 PLC for reference.
M
Memory:-
Value 1:-MW10
Value 2:-MW12
Result:-MW14
PLC
program Explanation:-
In-network 1
we have taken MUL instruction for multiplication of two different values. Value
1(MW10) will be entered from the HMI and value 2 (MW12) will be entered from
the HMI. Instruction is executed and generates output in the MW 14 word.
You can use MUL instruction for any application in
which you need to calculate the multiplication of two values.
