06:34 Saving the conditions for the variable
07:02 Adding a condition for enabling
07:32 Checking if the memory value is 1
This lesson discusses the functionality of resuming product transport between sensors. Memory is used in the form of markers or flags in the PLC program code. This solution allows for belt movement control and efficient production process management. Next, the lesson discusses defining a memory variable and the conditions in the program code that control belt movement. Conditions are introduced for when the variable should take the value 0 or 1. Finally, trigger conditions are added, which check for the presence of the product on the sensor and the value of the memory variable.
