Chapter 3 Force I/O
Disable or remove a force
To stop the effect of a force and let your project execute as programmed, disable or
remove the force.
• You can disable or remove I/O and SFC forces at the same time or
separately.
• Removing a force on an alias tag also removes the force on the base tag.
ATTENTION: Changes to forces can cause unexpected machine motion that could injure personnel. Before you
disable or remove forces, determine how the change affects your machine or process and keep personnel away
from the machine area.
Before you use a force, determine the status of forces for the controller. You can
check force status.
To determine status Use any of the following
I/O forces • Online toolbar
• FORCE status indicator
• GSV instruction
SFC forces Online toolbar
