-===== 3. Insert, Delete, and Copy Cells =====+===== 3. Write a Value to Memory ===== 
 + 
 +You can write a memory value from the selected ladder cell directly to the running board. **Right-click the ladder cell → Write Value to Memory**, or press ''Ctrl + Shift + W'' while the ladder grid has focus. 
 + 
 +{{ :products:mpino_studio2:memory-force-popup-marked-en.svg?1000 |Write Value to Memory popup beside the selected cell }} 
 + 
 +^ Marker ^ Screen item ^ How to use it ^ 
 +| **①** | Monitoring | Turn it on here if it is off. The **Write** button becomes available when monitoring communication is connected to the board. | 
 +| **②** | Address and current value | The selected cell's address is filled in automatically. If a function box contains several addresses, choose one from the list. For an empty cell, enter an address yourself. The current value comes from the board during monitoring. | 
 +| **③** | Value and Write | Enter a value and select **Write** or press ''Enter''. After a successful write, only the value field is cleared so you can write another value. | 
 + 
 +This popup accepts **M, D, C, T, and R** addresses. **P addresses cannot be written here.** The value changes on the running board and may affect an output or control condition. Check the address and value before writing. 
 + 
 +This one-address popup differs from [[en-us_products:mpino_studio2:menus_settings#run_menu|Run → Memory Write List]], where you register multiple addresses. Close the popup with ''Esc'', a click outside it, or **✕**.

-===== 4. Enter Contacts =====+===== 5. Connect Horizontal and Vertical Lines =====
  
-A contact reads an ON/OFF memory state or the result of a comparison and determines whether power flows through the circuit.+A horizontal line connects cells on the same row. A vertical line joins upper and lower branches.

 +Use horizontal lines to form a series circuit on one row and vertical lines to join the branches of a parallel circuit. 
 + 
 +===== 6. Define and Create NO, NC, and NOT Contacts ===== 
 + 
 +NO and NC contacts read an ON/OFF memory state or the result of a comparison. A NOT contact reverses the condition calculated before it.

-===== 5. Enter an Output Coil =====+===== 7. Use Positive and Negative Edges ===== 
 + 
 +A standard contact conducts while its condition remains true. An edge contact conducts for one scan only when the input changes state.

 +| Positive Edge | ''F11'' | One scan when the input changes from OFF to ON | 
 +| Negative Edge | ''F12'' | One scan when the input changes from ON to OFF | 
 + 
 +After placing an edge cell, enter the bit address or symbol whose change will be detected. Each edge cell tracks its previous state automatically, so you do not need a separate memory address for that state. 
 + 
 +Use Positive Edge for an action that runs once when a button is pressed. Use Negative Edge for an action that runs once when a button is released. 
 + 
 +===== 8. Create an Output Coil =====
  
 A standard output coil writes the result calculated by its contacts to a bit address on every scan. The coil address is ON while the condition is ON and OFF while the condition is OFF. A standard output coil writes the result calculated by its contacts to a bit address on every scan. The coil address is ON while the condition is ON and OFF while the condition is OFF.

- +
-  * **Series connection:** Power reaches the next cell only when every contact conducts. In ''M0 NO → M1 NO → P32 coil'', P32 turns ON only when both M0 and M1 are ON. +
-  * **Parallel connection:** Power continues after the branches rejoin when any connected branch conducts. If M0 and M1 are connected in parallel, P32 turns ON when either one is ON. +
