8055 CNC CONFIGURATION
SOFT: V02.2X
Central unit
Central Unit (CPU) configuration
The configuration of the central unit depends on each application. The –CPU– and –AXES– modules
must be part of all configurations.
The –CPU– module must be the first one from the left. The rest of the modules do not have to follow
a particular order and may be interchanged according to personal preferences and connection
possibilities of the machine.
The CNC has a PLUG&PLAY system that recognizes the configuration of the central unit. To do that,
regardless of their physical location, each module has a logic address or device select code which
identifies it within the internal configuration of the CNC. The logic address (device select code) for
each module is factory set as follows:
–Axes– module Logic address 2.
–I/O– module (1) Logic address 3.
–I/O– module (2) Logic address 4.
–I/O– module (3) Logic address 5.
Nevertheless, except in the axes module, these logic addresses may be modified at will. To do that,
use the microswitches located in one of the corners of the printed circuit board.
The logic address is set in binary code between 1 and 14. Logic address "0" and "15" are reserved.
Logic addresses 0 and 15 are reserved.
When using several –I/O– modules, the CNC assumes the one with the lowest address as the first
expansion module, as –I/O– (2) module the next address and as –I/O– (3) the one with the highest
address number.
