How to
Releasing a Forced Value
You release a forced value to return to its normal status.
When you force a value, you override all input from the system. For example, if a schedule is set to enable a device at 09:00, but you want to enable it at 08:00, you can force the enablement at 08:00.
You can manually release a forced value at any time or you can automate the release, using a Timed Force utility object to specify the duration or end time of the force. For more information, see Timed Force Objects .
When you release a forced value, the value returns to its normal status.
In WorkStation, you can view the unforced value, which is the real value from the system, at any time. For more information, see Viewing an Unforced Value .
