This is a PLC Program for Automatic Parameter initialization when power up.
Problem Description
In many applications, it is necessary to initialize some data when the machine is powered up.
Sometimes due to power failure, the value in some parameters becomes zero.
Due to this problem, the operator has to feed all data again or every time during power failure.
When the machine gets powered up, at that time necessary parameters should be initialized automatically.
Here we discuss this issue with some basic ladder logic.
In this case, we need to write the logic in the PLC program so all parameters will be initialized automatically.
We can also set a manual initialization button so the operator can initialize data while the machine operation is running.
Here we will consider the machine set speed as data and it will be initialized automatically when the machine turns on.
If the operator wants to reinitialize the set speed during the running cycle then he needs to do it through the initialization button.
Here is the PLC program Automatic Parameter initialization when powered up.
List of PLC inputs/outputs
Note: The above PLC Logic provided for basic idea about application of PLC Program for Automatic Parameter Initialization when Power UP. The Logic is limited and not complete application.
