Division of two operands using an example.

Division of two operands using an example.

Application:-DIV 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 subtraction DIV instruction is used for subtraction of two values for any data records to understand this instruction take one example. Consider one RTD sensor, it is giving data of temperature to the programmable logic controller in a standard format and this data is 250 degree (room temperature) so you need to calculate this value and need to divide by a factor of 10 so you will get the actual temperature.

This is a simple example for an explanation. We can use this concept in any application or any data calculation.

 

PLC program:-

Write the ladder program for DIV 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:-

RTD reading:-MW10

Factor:-MW12

Actual value:-MW14

PLC program Explanation:-

In-network 1 we have taken DIV instruction for our example. RTD sensor is reading data in the MW10 and factor entered in the MW12. Once DIV instruction will be executed, it will show results in the MW14.

Here RTD reading is 250 degree and factor is 10 so it will show 25 (250/10) in the actual temperature.
