Description

Sets the state of the tank to Tank_ScheduledDown, waits for the specified scheduled downtime, then sets the tank state back to its previous setting. If you defined a scheduled downtime using the location downtime dialog, call the Tank_GoDownSched subroutine in the downtime logic rather than use a WAIT statement. If the downtime is for cleaning and you will return the tank status to idle, use the Tank_DoPrep subroutine.

Use Tank_GoDownSched to shut down a tank for a scheduled task or event (e.g., interim maintenance or end of scheduled workday). Since the tank uses a scheduled downtime, the time lapsed during the event does not record as a downtime.

Components

<Tank ID>

The tank name or location index number.

<Down time>

The duration (in time units defined in the General Information dialog) of the scheduled downtime.

Example

Every 4 hours, a technician must check the fill line from a dry supply bin. The time required to check the line is normally distributed with a mean of 10 minutes and a standard deviation of 3 minutes. To define this behavior, define a clock-based, scheduled downtime for the bin to occur with a frequency of 4 hours. In the logic defined for the downtime, enter the following:
