Forcing an I/O Value
Use a force to override input data or logic when you need to:
• test and debug your logic.
• check wiring to an output device.
• temporarily keep your process functioning when an input device has failed.
ATTENTION
Forcing can cause unexpected machine motion that could injure personnel. Before you install, disable, or
remove a force, determine how the change will effect your machine or process and keep personnel away
from the machine area.
Enabling I/O forces causes input, output, produced, or consumed values to change.
If you remove an individual force, forces remain in the enabled state.
If forces are enabled and you install a force, the new force immediately takes effect.
