7.4 Synchronous Dual Conveyor
Station software versions 605.xx and 7xx provide enhanced data quality for operation with
synchronous dual conveyor.
This chapter describes the operating data written in the OIS database during production with
synchronous dual conveyor in station software 605.xx and 7xx.
NOTICE
Previous station software versions do not provide the described data quality.
7.4.1 Station Software 605.xx
PCB
The attribute lBoardNumber is increased in step size of 4 for both transport conveyors.
Until now, the attribute was increased in step size 2.
For synchronous dual conveyor, two boards are written in the OIS database.
Example
3 boards are produced without synchronous dual conveyor on the right transport conveyor.
After that, 6 boards are produced with synchronous dual conveyor.
Then, the following board numbers exist in the OIS database:
1, 5, 9, 13, 13, 17, 17, 21, 21.
The boards with lBoardNumber 13, 17, 21 exists once for ucConveyor = 1 and once for
ucConveyor = 2.
Cycle time sDuration and end date/time dtTime are identical for synchronous dual conveyor.
Component consumption
The component consumption is sent in sum for every board.
For the example described above, the following consumption data is available for the following
board numbers: 1, 5, 9, 13, 17, 21.
Events
The PCB_BEGIN, PCB_END and PLACING events are sent only once for synchronous dual
conveyor.
For the example described above, PCB_BEGIN is only available for the following board numbers:
1, 5, 9, 13, 17, 21.

7.4.2 Station Software 7xx
The 7xx station software handles synchronous dual conveyor differently than the 605.xx software
does. This station software handles each board individually. This means that each board gets its
own board ID (IBoardNumber) and the events PCB-BEGIN and PCB_END are sent for each board.
OIS generates a database entry for each board in the BOARD table and an event entry for each
event in the EVENT table in the OIS database.
7.5 MTC / WPC Track
In previous station software versions, the MTC / WPC was located on track 0 (sTrack) in the OIS
database. In the SIS database these components were located on track 1 (sTrack). This caused a
difference between the OIS station view and the SIS line view.
As of the station software versions 605 and 701 the MTC / WPC is located on track 1 in both
databases.
NOTICE
The V_USEDCOMPONENTS6 view (see section 5.11.1) shows track 0 (sTrack) as
track 1.
7.6 Quad Lane Support
The station software as of 702 supports the "Quad Lane" conveyor mode. This mode means that a
placement machine is equipped with two lanes per conveyor, i.e. each conveyor has two sub-
lanes. Each sub-lane can handle a PCB autonomously but not independently. The meaning of “not
independently” is, that the two lanes of a conveyor always run in synchronous mode, i.e. PCBs on
both lanes enter and leave a certain processing area at the same time.

The sub-lane information can be found in the lSubConveyor column in the BOARD table of the OIS
database.
If the station does not run in "Quad Lane" conveyor mode, this entry contains the value "0". In case
of "Quad Lane" conveyor mode, this entry is either "1" for the right lane or "2" for the left lane.
Applied to the example shown in the figure above, this would result in the following table entries.

NOTICE
Please note that each PCB gets its own lBoardNumber. The values shown in the
lBoardNumber column are just examples and do not mean that the PCB on the left lane
on the left conveyor always gets the lowest number in "Quad Lane" conveyor mode. It
just means that each PCB gets a unique lBoardNumber.
This behavior is the same for synchronous and asynchronous mode.
The OIS server adds the following board specific database entries while a board gets produced.
EVENT table
● New Event: PCB_BEGIN when the production is started.
● New Event: PCB_END when the production is completed.
BOARD table
● A new row is added to the BOARD table describing the PCB.
USEDCOMPONENTS table
● A new row is added to the USEDCOMPONENT table for each component that has been
placed.
In "Quad Lane" conveyor mode these entries are written for each of the quad boards which can be
produced at a specific time.
