The line computer uses an UNIX based operating system with Siemens specific desktop
software as a User interface. The line computer is principally used as an offline pro-
gramming station for preparation of PCB programs and also as a monitoring device to
record machine / line performance.
The relationship between the LC and the station is obviously an important one. Firstly
the machine specification (options fitted, nozzle changer configuration, etc.) is pro-
grammed at the LC and saved under the NGfile in the xxxxxx.st directory in Stationen
directory in Master Data. This file also contains the data regarding nozzle specifications
such as length and vacuum thresholds. This .kd file is converted at the line computer to
become the 60$ file. This file is sent to the station to become the ,GHDOPDfile.
The PCB placement program is transmitted to the station from the LC. The source file at
the LC is the TG file, which is contained within the specific xxxx.la directory for each
PCB and subsequently for each station. This file is converted at the line computer to
become the 61% file. This file is sent to the station to become the $NWXHOOQX file.
The full path at the LC for the .SNB file is
xxxx.la/.ad/SMT.ak/xlinie.va/xxxx.ar/xxxx.sr/SNB
Together with the placement data the LC also transmits the set up required at the sta-
tion. The source file at the LC is the NG which is contained within the specific xxxx.ar
directory for each set-up and subsequently for each station. This file is converted at the
line computer to become the 656 file. This file is sent to the station to become the
$NWXHOOUX file.

The station computer for current software releases uses Windows NT as the operating
system with Siemens Desktop software acting as a graphical user interface (GUI).
When the machine is booted, as a default, the station computer is looking to communi-
cate with the line computer. Once this communication is established the station will
await the processing data, which is the job to be scheduled from the line computer.
When this data is sent to the station the current program, set up and nozzle configura-
tion is updated.
Should there be a problem with the LC or the network connection to the LC it is possible
for the station to work in ‘Stand Alone’ mode. In this mode it is possible to select the
Aktuell.nu file as the current program and run the machine. This Aktuell.nu file is always
the last job that was scheduled over to the machine from the line computer.

The machine data files used by the station are contained within the directory
&65'DWHQ6UFPD. Here you will find numerous .ma files which, as a rule should not
be edited. The important files for us to consider are the following.
5HDOPD Contains many of the calibrated machine offsets
3LSBRIIPD Contains all the calibrated segment offsets 1 & 2
3LSBDNWPD Contains the current nozzle changer configuration.
3LSBYHUPD Contains the calibrated data regarding the nozzle changers.
$FKVBYHUPD Contains all the axis Zero point correction and max / min travel values
$NWXHOOPD Contains the current nozzle configuration on each head at the station.
This is the file that is changed when a nozzle change is performed at the
station. It is also used to tell the station the current nozzle configuration at
the heads and is therefore used when the station is operating in ’Stand
Alone’ mode. It is also used to compare the current nozzle set up with the
required nozzle set up when a job change is performed and therefore
prompt a nozzle configuration change.
0DSS[[PD These files contain the mapping information for the gantries.
In the latest software for HS50 and S25 machines, only the .ma files that are changed
by calibration are available to edit in the Srcma directory. The other .ma files are stored
in an ‘Access’ database and can only be edited offline.
Other important files we should consider at the station are contained within the directory
&65'DWHQ6UFOU. Here you will find the following files.
$NWXHOOQX The current PCB program at the station, which is derieved from the .SNB
file at the Line computer.
$NWXHOOUX The current set up at the station.
,GHDOPD The file that contains the nozzle length and vacuum threshold specifica-
tions and machine options.
,QWHJUDWHGIURP6:[[LQWRWKHGDWDEDVH
9DNXXPPD Contains all the data regarding vacuum tolerances and thresholds.
9DNB]PD Contains the nozzle types for which vacuum is switched on early during pick up
(as the Z axis top sensor is activated).
6FDQSDUDPD Contains the nozzle types for which a visual check is carried out after placement,
and also the parameters for this check.

For the current software versions the machine controller acts simply to control all
machine functions and sequences. It is a standard industrial PC using a RMOS operat-
ing system.
The machine controller is in effect the ‘brain’ that controls the machine, which communi-
cates with the station computer to obtain the PCB program and machine data informa-
tion. On boot up the machine controller initiates the communication with all the various
machine systems, the axis cards, CANBUS, ICOS and most notably the station com-
puter. If any of these communication links should fail the station computer software will
never completely boot (the message ‘Software Booting’ will remain indefinitely on the
screen). This is why it is necessary that when a station is shut down and then rebooted
the machine is actually turned off. Without this the machine controller is not rebooted
and therefore the communication sequence is not restarted.
