Setting a Timeout on a Forced Value

You set a timeout on a forced value when you want the value to be unforced automatically at a fixed time.

action_close

When you force a value, all input from the system is overridden. For example, a schedule is set to start a fan at 09:00 but you want it to start at 08:00. In this case, you can force the fan to start 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 .
