This example demonstrates how to add 5000 and 400, then store the result in AC0. The data is stored in VW200. The program code is shown below.
LD I0.0
MOVW VW200, AC0 // Load value from VW200 into AC0
+I +400, AC0 // Add 400 to the value in AC0
This simple program illustrates a common operation in PLC programming where values are retrieved from memory, processed, and stored for further use. It's useful in applications such as industrial control systems, automation, or data processing tasks. Understanding how to manipulate data using instructions like MOVW and +I is essential for anyone working with programmable logic controllers. Always make sure that the data types and addresses used are correct to avoid errors in execution. This kind of operation is fundamental in many real-world scenarios where precise control and calculation are required.
In places where the grid availability is zero or where there are high instances of power cut, Off-grid systems are an apt solution for relief from power cuts and they can be installed with a standalone inverter with a separate or integrated charge controller.
If the off-grid system is designed with appropriate solar panels and Battery, it can supply power throughout the year without ever relying on the grid power. If the system is under designed then the battery is always in very low status. We use inverters from reputed brands like Growatt,Goodwe and HuaWei for our off-grid systems.
