5.6 Possible Placement Data Deviations Between SIPLACE
Explorer and OIS
The number of consumed components, rejects and boards can differ between SIPLACE Explorer and
OIS.
In OIS, each data set has a time stamp (consumed components, rejected components and each board).
If you start an OIS query for the consumption within a specific time period, via SQL Query, OIS will issue
the number of data sets which have a time stamp within this period.
SIPLACE Explorer, on the other hand, assigns the components to the boards on which they are to be
placed. If you start a query for the consumption within a specific time period, SIPLACE Explorer will issue
the number of components which have been placed on the boards which were produced within the
defined period. This difference becomes clearer when we consider production in 2 placement areas.
The following diagram illustrates the difference.
Example: 8 boards were placed on a machine with 2 placement areas. The diagram shows 3 timelines:
• Components for placement area 1
• Components for placement area 2
• Boards
The components X on the timeline for placement area 1 show the possible timestamps for those
components which were placed on board X.

If you start an OIS query via SQL Query, for the time between T1 and T2, the result will show the total
number of components which were placed on all 8 boards minus the number of components which were
placed on board 1 of placement area 1.
If you start the same query via SIPLACE Explorer, the result will show the total number of components
which were placed on all 8 boards.
In this example, the result in SIPLACE Explorer will be higher than the number shown in OIS.
However, this is not always the case. If board 9 is placed (in placement area 1 in the diagram), SIPLACE
Explorer will not count the components which were placed on this board and will therefore show fewer
components as the OIS.
For this reason, there will also be deviations between OIS and SIPLACE Explorer in the determination of
component reject numbers.
5.7 Status Display Deviations Between SIPLACE Explorer and OIS
There is a special OIS status module realized in SIPLACE OIS. This OIS status module is shown in the
SIPLACE Explorer status module which matches the SEMI E10 status module. This may lead to
deviations in the states and status times shown between OIS and SIPLACE Explorer. A direct
comparison is therefore not possible.

1. Differences in status models and their states:
OIS has a status model for each of the two processing areas but no status model for the entire machine.
SIPLACE Explorer, on the other hand, does have a status model for the whole machine (E10).
OIS recognizes the following 5 states:
• Running
• Starved
• Blocked
• Interrupted, fault
There are no substates.
The E10 status model in SIPLACE Explorer recognizes the following 6 states:
• Productive
• Standby
• Engineering
• Scheduled Downtime
• Unscheduled Downtime
• Nonscheduled Time
• There is also a special status Unknown.
Many of these states have substates, such as:
• The status Productive has the following substatus:
o Zone1Productive_Zone2Productive, Zone1Productive_Zone2Blocked
o Zone1Blocked_Zone2Productive, Zone1Productive_Zone2Starved
o Zone1Starved_Zone2Productive.
The OIS states can not be shown by the SIPLACE Explorer E10 status.
2. Differences between machines with two processing areas:
Since OIS does not have a status model for the entire machine (just one for each processing area),
although it should shown the times for each status (Running, Starved, Blocked, Interrupted and Fault) for
the whole machine, the times for both status models are only taken into account to 50% each by the
status display for the machine.
This means that, if an X4 machine places one board for one minute in processing area 1 and then places
for another minute in processing area 2, the machine should show 50% of the time in the status Place
and 50% in the status Starved, provided a board is placed into the machine every two minutes.
