Summary: The ArchFX React Production Overhead Display (OHD) enables line operators to see the most pressing information about production status on their line including whether the line is running or down, current product name, performance and quality statistics, a list of the worst feeders and nozzles on the line, and which machines are running, idle, or down.
You use these filters to select which Line you want to view:
- Site: Select the site you want to view.
- Area: Select the area(s) you want to view (or "All" for all areas).
- Line: Select the line(s) you want to view (or "All" for all lines) in line-oriented use cases.
The large line status panel makes it easy to see from a distance whether the line is running, idle, or experiencing a downtime.
The job data panels show you the name of the current product being built, the number of Components Per Hour (CPH) being placed, the Target Takt Time for the job, and the Actual Takt Time.
- CPH is the actual number of components that have been placed by Pick and Place machines on the line in the last 60 minutes.
- Actual Takt Time is a moving average of the last five takt times observed on the line.
Units Per Hour Per Shift
This panel shows you the number of Units Per Hour produced during the current shift. The target takt time is shown as a red dotted line.
For hours before the current hour, the panel charts what the target was for that hour (red dotted line) and what the actual production in units was during that hour (blue bar).
For the current in-progress hour, the chart continuously adjusts both the target (how much should have been produced up to this point in the hour) and the units produced (how much was produced up to this point in the hour). For example, if it is 7:15 a.m. and a job with a 60 second cycle time has been running since before the start of the hour, Target as of 7:15 a.m. is 15, and UPH is however many units were actually produced during that 15 minute interval. If that job continues running for the rest of the hour, by the end of the hour, Target will have reached 60.
Last Refreshed, Start Time, and Time to Complete
- Last Refreshed shows the time at which the Production OHD was last updated (in the current time zone).
- Current Job Start Time shows the time in the current zone that the current job began.
- Time to Complete shows how much time it will take for the current job to be completed. It is calculated by dividing the remaining units to create for the current job by the current units per hour (which is derived by dividing 60 minutes by the Actual Takt Time in minutes).
The "Shift Performance" bar shows the breakdown of time on the shift between running time (green), idle time (yellow), planned downtime (blue), unplanned uncategorized downtime (dark red with hash marks), and unplanned categorized downtime (bright red).
The total "downtime" reported on this performance bar only includes the time consumed by automatically detected downtime events during the current shift, not by cycles that are slower than the target takt time but not slow enough to reach the downtime detection threshold. (See What's the difference between downtime and time lost? for details.)
The Quality panels show data sourced from the chosen quality machine on the line. The Quality panel shows the percentage of units that passed quality inspection. Passed / Failed shows the number of units that Passed (on the top) and the number of units that Failed (on the bottom).
Worst Nozzles lists the nozzles on the line with the largest number of mispicks from most mispicks downward.
Worst Feeders lists the feeders on the line with the largest number of mispicks from most mispicks downward.
The Line Diagram represents the status of each machine along the line by color:
- Green means that the machine is not showing an error code and has recently signaled a product completion event within a time period equal to twice the current cycle time for the machine.
- Yellow means that the machine is idle. It is not showing an error code, but it has not signaled a production completion event for a time period greater than twice the current cycle time for the machine.
- Red means that the machine is signaling an error code.
- Gray means that the machine does not have a hardware or software connector configured or React has received no data from the machine in the last hour, so React has no data about the machine's state.
The red caret (far right in the screen shot above) indicates the machine that is the current bottleneck for the line.
