3.1.1. PC LINUX BOARD
The machine is provided with a Linux PC board on which
the high-level machine software is memorised.
The Linux PC board receives the Ethernet connection from
the LAN1 port and is internally connected to the MAB
board via RS-232. The Linux board has RS-232 and USB
ports necessary to connect some accessories like the
scale.
The Linux PC board is powered with 12V.
3.1.2. MAIN AUTOMATION BOARD (MAB)
The machine management firmware MAB board is saved
on the MAB board. The orders sent by the high-level
software are managed at MAB level. This board organises
the machine cycle by interrogating and sending orders via
RS-485 to the slave boards of the single circuits.
The MAB board is supplied with 24Vdc.
The MAB board controls directly:
