Click to select a downtime period from the histogram. Selecting a downtime period from the viewer will display its details in the Edit Downtime section below the histogram. Categories and codes can be assigned to the downtime period, as well as options for additional adjustments to downtime periods, which can be made using the following three modes:

Single – This function is used when a user wants to assign a downtime code to one single event on the displayed date/time range. A machine operator would use the single assignment mode to assign a job setup code soon after starting a new production run, for example.

Multiple – Multiple Assignments is used when a user has multiple downtime events that require the same downtime code. Instead of filling out the assignment form for each event, an operator is able to fill out only one form for all events.
Note: Multiple assignments can only be used to assign codes to unassigned downtime events (shown in red).

After clicking on Single or Multiple below the graphic, click on the slices of time you would like to edit. You are then allowed to edit the following:

  • Category: You can select a code category from the drop down list. This category will affect what codes appear in the code drop down.
  • Code: Choose a code from the drop down list. The contents of this list are affected by the category you chose earlier.
  • Notes: Here you may enter notes on the time period. Some codes may require you to write notes.

Merge – Merge Multiple Assignments is used when multiple downtime events separated by some period of machine runtime are related.
Note: When using this function, the start and end events must be unassigned downtime events that (shown in red).

After editing or adding information click the save  icon. Clicking back WILL NOT save changes.

Automatic Downtime Assignment

Using PLC Values, it’s possible to have downtime codes automatically assign rather than having to rely on manual input. PLC Values must be entered onto the PLC itself, and then the correct value must be assigned to the proper code (from the Manage Codes page).

It’s also possible to have downtime codes automatically enter a downtime note as well, using the tag type called Downtime note.

Any code that is assigned automatically will show as being assigned by System Account user to indicate that it was automatically assigned.  Other users can still manually assign downtimes or edit previous downtime assignments – doing so will show their name in the Assigned By column. This is done for record-keeping purposes and tracking user input (will show up on downtime tracking exports and Pareto charts).

If you have questions about automatic downtime assignment, contact us for details.
