The rack cutting DIGITEC consists of four cards and power supply.
The housing for the DIGITEC boards is an aluminium RACK with a black anodised front panel and (28TE x
6HE) dimensions that permits the housing of up to 7 Double European format boards.
A Backplane (DIGITEC board 018.0) is mounted at the rack’s upper rear part, and given that it is an AT 96
standard BUS, it serves the purpose of interconnecting the boards on the rack.
Its lower part houses the connectors that permit the connection of all the signals coming from or going to the
field by means of a series of flat cables connected to Digitec 008 boards.
A feeder positioned on the outer left side of the rack provides the voltage necessary for the function of the
entire rack.
The following boards may be seen in sequence by looking at the rack from the front and moving from the left
to the right:
DIGITEC 013.2 board CPU
DIGITEC 011.0 board(s) Cutting management
DIGITEC 016.0 board (s) Digital I/O management
DIGITEC 017.0 board Analog I/O management

POWER SUPPLY:
The three voltages necessary for the rack (+5V, +12V, -12V) are provided by the feeder and wired towards
the Backplane in the rear part of the rack. The feeder has an automatically selected input voltage range from
127V/370 VAC/DC.
The maximum output currents are:
+5V 10A
+12V 4A
-12V 0,6A
DEVICE NET HMS AB4004: Ab4004 is a integrated fildbus communication module.
Fieldbus Connector (A)
The Anybus-S provides fieldbus connectors according to each fieldbus specification.
Configuration switches (B)
DIP switch select baud rate and MAC ID.
On a DeviceNet network, each node must be assigned it’s own unique Mac ID. The Mac ID is a value
between 0 an 63 used to identify each node. The Mac ID and Baud rate settings can be set either using a
physical DIP-switch or via the application interface using mailbox commands.
Switches 1 and 2 specify the baudrate, while switches 3 though 8 specify the Mac ID:
013.2 CPU CARD:
The 013.2 board is a CPU mounted on an AT96 Bus.
Connectors:
Mouse (AUX),
Keyboard (KBD),
Two serial gates (COM1 COM2),
Parallel gate (LPT1),
Video output (VGA)
Ethernet
It also provides the hard disk in which the software for the management of the entire cutting system is
memorised (using a PCMCIA ATA Board). MEMORY CARD.
The hard disk can be easily removed by pressing the black key positioned nearby.

Comand Buttons and Dip Switches:
RUN-STOP selector permits the stopping or starting of process management.
Reset button triggers the system re-starting procedure and we therefore discourage its use during the
operation of the machine.
The board features a series of eight dip-switches that cannot be re-configured without compromising the
satisfactory operation of the system.

POWER-UP SEQUENCE:
The following steps indicate the sequence of power-up.
- Programming card
After a power up of the rack ,the system operation loads the programs serving to initialize the Card 011.0,
016.0, 017.0. If the programming was successful, the led named PROG in the cards (011.0; 016.0; 017.0)
(yellow) goes off. The led on 013.2 named HD blinks quickly until the initialization program was finish.
- Initialization phase
When the programming card finish, the management program loads the initialization function.
During this phase the red led Fault on 016 card goes off.
Field bus: the device net of the AB4004 card has a led blinking sequence from red to green. Finally if the left
led is green it means the initialization of the module was successful; if the communication was established
with the master plc on the net: the right led became green.
- Run mode
During a normal execution of management program the led RUN of the 013.2 card is always ON, and the led
WD blinks with a 0.5 Hz frequency.
- Bad execution
If during a normal execution the management program stops and restart the power-up sequence: means that
there is a problem on 5V feeder alimentation (power).
SUBSTITUTION CARDS:
The following important steps must be taken when replacing any DIGITEC card:
- make sure that the new board’s identification number located on the front panel’s lower handle or printed
onto the board itself (e.g. 011.0) is the same as the one on the board being replaced, unless differently
indicated by DIGITEC.
- make sure that the number written after the letters AR printed on the board are equal to or greater than the
number on the board to be replaced.
- position all the switches in the same position that they occupied previously in the board where they have to
be replaced.
- position all the jumpers in the same position that they occupied previously in the board where they have to
be replaced.
