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.

➠ The job control facility of the line computer sends the placement program to the station com-
puter via the SIPLACE LAN

➠ The program is buffered on the station computer, where it is the converted and forwarded by
the sequence control facility to the machine controller over the SIPLACE LAN
➠ The placement data is stored in the machine controller RAM, from where it is processed in se-
quence.
➠ During the placement process, the machine controller sends status reports (error messages,
operator requests, information on the processing status) to the station computer via the LAN.
➠ In accordance with the placement sequence, all production data ( information on errors, dura-
tion of the placement process, etc.) is transferred from the stationcomputer to the line com-
puter, where it is recorded and displayed using appropiate evaluation software (MaDaMaS -
machine data management system).

➠ If several HS-50 placement machines are connected in a line, the same modules as before
communicate via the LAN, only in larger numbers.
➠ With this configuration, the only difference in the communication process in the SIPLACE LAN
occurs between the line computer and the station computers.
➠ In this case, the job control facility transfers the placement program to the individual station
computers in accordance with the line configuration.
➠ Similarly, the line computer receives the production data of all connected station computers.
➠ The individual station computers and machine controllers communicate as normal.
