To enable Write and Force functions while in STOP mode, choose the Debug > Write-Force Outputs in STOP menu command. The S7-200 PLCs support writing and forcing outputs (both analog and digital) while the PLC is in STOP mode. As a safety precaution, you must specifically request this functionality to be enabled in STEP 7-Micro/WIN 32. The menu option Debug>Write-Force Outputs in STOP enables you to Write or Force outputs while the PLC is in STOP mode. Warning If the S7-200 PLC is connected to equipment when you write or force an output, these changes may be transmitted to the equipment. This could result in unanticipated activity in the equipment, which could also cause death or serious injury to personnel, and/ or damage to equipment. Each time STEP 7-Micro/WIN 32 is opened, the menu option defaults to unchecked, and you are prevented from writing or forcing outputs while the PLC is in STOP mode. Checking the menu option enables writing and forcing for the current editing session with the current project. When a different project is opened, the menu option returns to its default state and you are prevented from either writing or forcing output addresses while the PLC is in STOP mode.
