Explanation of the List of events:
For each event that occurred during the evaluation period a line containing three columns is displayed.
Column 1: Event
Name of the event (shutdown cause)
Column 2: Duration [hh:min:ss]
Duration of the event (shutdown of the station) during the assembly of the
PCB specified in hours/minutes/seconds
Column 3: No.
Number of times an event has occurred during the assembly of the PCB

● Click on the icon.
The "Availability" evaluation is redisplayed.
16.2.8.7 "System Diagram" Evaluation
The "System Diagram" evaluation depicts the time percentages of the various states of the individual stations
over the selected evaluation period (= time basis). Moreover, general informationen and production figures are
listed as well.
The system diagram is mainly of significance to the operating personnel as it displays important information
about every station thus allowing any troublespots and load imbalances to be identified at an early stage.
The "System Diagram" evaluation is called up from the "Availability" chart. It is available for all stations.
- Calling up the "System Diagram" evaluation for all stations
● In the overall view click on the icon in the "Availability" chart.
The System Diagram including all stations of the line is displayed (see Fig. 16.2.8).

Explanation of the System Diagram:
Bar chart: For each operational status of a station (Running, Waiting, Blocked, Interrupted,
Failed) a colored bar is displayed indicating the proportion of time allocated to a
particular station in relation to the total processing time of all PCBs during the evaluation
period. The percentage value corresponding to the respective proportion of time is
indicated above every bar displayed.
Status:
Running --> The station is carrying out placement operations and performing position and
(green bar) inkspot recognition.
Waiting --> The station is waiting for a PCB from the preceding station, for the PCB
(yellow bar) in the center conveyor, for the output conveyor to be cleared, or for data.
Blocked --> The station is waiting for the subsequent station to take over the PCB from
(purple bar) the output conveyor so that the currently completed PCB can be conveyed
out of the center conveyor.
Interrupted --> The assembly of the PCB on the station was interrupted owing to the
(blue bar) following events, e.g.:
Abort button actuated, Emergency stop actuated (compressed air failure,
control deactivated), Stop button actuated, Cycle mode active, Single function/
Vision menu, Keyswitch in slow position, etc.
Failed --> The station is out of order with no outside intervention having taken place, e.g.
(red bar) after the third unsuccessful attempt at picking up a component.
Total time [hr:min:sec] This column shows the overall time in hours/minutes/seconds the particular
station has spent in the individual states during the evaluation period.
Utilization rate [%] This column contains the time percentage in relation to the total assembly
time the particular station has spent in the "Running" status during the evalua-
tion period.
The indicated value corresponds to the utilization rate achieved.
Availability [%] Availability of the line/station (see section 16.2.8)
