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)

16.2.9 "Performance" Evaluation
An essential criterion for the operation of the SIPLACE machines is the calculation of the placement rate. Apart
from the absolute number of components placed, also the ratio of the actual performance to the theoretically
achievable performance is of significance.
This relative performance is calculated as follows:
The number of minutes elapsed since the completion of the last PCB is displayed below the "Performance"
chart (see also section 16.2.9.1). In addition, the theoretical performance and the actual performance of the
machine are indicated as well as the number of PCBs per hour.
The "Performance" evaluation is available for the entire line as well as for all placement stations.

- Calling up the "Performance" evaluation for the line
● On the menu bar select EVALUATIONS --> Overall view.
The "Overall view" evaluation including the "Performance" chart is displayed
(see Fig. 16.2.1).
- Calling up the "Performance" evaluation for all placement stations
● On the menu bar select EVALUATIONS --> Performance.
Or else:
● Click on the blue bar in the "Performance" chart of the overall view.
● The "Performance" chart is displayed for all placement stations (see Fig. 16.2.9)
