ODI Classifying Unknown Downtime

Overview

There are many scenarios where a large block of time did not have an appropriate planned or unplanned downtime entered when it should have been. There are cases where a downtime needs to be entered and the start time set to an earlier time, or cases where previous stops need to be filled in after the machine has already gone back into cycle. The Operator Data Interface provides the ability to modify Unknown Downtimes that have previously occurred for these scenarios.

There are two methods of classifying unknown downtime from ODI, both of which are controlled by permissions. The first method is to enter a planned or unplanned downtime and set the start time of the downtime to when the currently active unknown downtime began. The second method is to view a list of previous unknown downtimes and back fill each with the appropriate downtime reason.

The Modify Time Stamp button has two possible options: Current and Previous. If the permissions are enabled for only one of the options then when the Modify Time Stamp button is pressed the appropriate functionality will be the only available option. If data is modified by either the Current or Previous option an audit record is written to capture the modification. The modifications can be viewed with the Modified Data report.

Setting the Start Time for the Current Downtime Being Entered

The Current option is used when the equipment is currently in an unknown downtime and the start time needs to be adjusted to an earlier point in time. First, select the downtime you would like to use. When the button is pressed a date and time selector will be displayed which will default to the time in which the unknown downtime started. The start time for the downtime that is about to be entered can be set to when the unknown downtime started simply by pressing the Set button. By default, the time can also be set to any time from the most recent status change up until the current time. The timestamp can be set to any previous time if the Replace Data setting is enabled. If the time stamp to be used has been modified the date and time will be blue to identify that it has been changed, or red if the selected time is prior to the most recent status change. Once the time has been modified a downtime can be submitted by pressing the Start New Status button. If the downtime category is changed (e.g. planned is selected instead of unplanned) the timestamp changes will reset. Once the time has been modified it can be reset and changed back to the current time by pressing the Now button on the date and time selector.

Classifying Previous Unknown Downtimes

Using the Previous option within the Modify Time Stamp button on the Operator Data Interface screen allows users to alter recent unknown downtimes. The Previous option will display a list of all unknown downtimes within the specified time frame that are greater than the minimum time for unknown downtimes that can be classified. Rules that control the list of qualifying modifiable Unknown Downtimes can be configured on the Manage tab on the Operator Data Interface Settings form. More information on ODI Settings can be found here.

Backfilling Current Unknown Downtime

A status change can automatically backfill when the machine is in Unknown Downtime without using the date/time selector. In order to do so the standard ODI – Planned Downtime Start and ODI – Unplanned Downtime Start expressions will need to be removed and replaced with different expressions. The replacement expressions will trigger an auto-backfill when the machine is in Unknown Downtime, but will perform a standard status change if the machine is not in Unknown Downtime. More information can be found on the ODI Expressions page.
