7.2 Machines with Two Processing Areas

For example: SIPLACE SX4, X4, X4 S, X4i, X4i S, X3, X3 S, D4, D3, HS-50, HS-60, HF

There is a separate state machine for machines with two processing areas.

NOTICE

If an X4 machine spends one minute placing a PCB in processing area 1 and then

spends another minute placing a PCB in processing area 2, the machine should show

50% of its time in placement state and 50% in waiting state if a PCB is inserted into the

machine every two minutes.

On this basis, it is necessary to map an X4 machine to at least two state machines. In other words,

one state machine for each processing area. The machine for a processing area is therefore the

same as the machine for an X2, for example. This means that the states of processing areas 1 and

2 each account for half of the state of the X4 machine.

When an event occurs on the X4 machine, this event is only forwarded to the appropriate machine

for the processing area, depending on the assignment of event to processing area. If an event is

not assigned to any processing area, it is forwarded to both processing area machines. See also

the following diagram.

7.3 I-Placement

For SIPLACE X4i machines with station software version 7xx, the "I-Placement" option is

supported.

In previous OIS state machines for SIPLACE Placement machines, it was only possible to create

states for one processing area at a time; even with dual-lane transport, only one PCB was

produced at any one time.

Starting with this version, the "I-Placement" option can process 2 PCBs simultaneously in one

processing area. This functionality has caused changes to the OIS state machine.

Previous station types are also supported by the new OIS state machine.

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.
