MACHINE PARAMETERS
SOFT: V02.2X
PLC Parameters
IANA5V (P130)
On an 8055 CNC with –Vpp Axes– module, this parameter indicates the range to be used in each
differential analog input of the module's connector X7. A range of ±5 V or ±10 V may be assigned
for each analog input.
This parameter has 16 bits counted from right to left.
Each bit has a function or work mode associated with it. Assigning the value of ·1· activates the
corresponding function. The default value for bits 13 to 16 is ·1· (±5 V range).
Bit 12 - 15. Average range for the analog inputs.
These bits refer to the 4 analog inputs of the –Vpp Axes– module. Every bit corresponds to an analog
input and indicates whether it uses a ±5 V range (bit=1) or a ±10 V range (bit=0).
NUILO1 (P131) NUOLO1 (P132) NUILO2 (P133)
NUOLO2 (P134) NUILO3 (P135) NUOLO3 (P136)
NUILO4 (P137) NUOLO4 (P138)
These PLC machine parameters may be used to redefine the numbering of the inputs/outputs of
the local expansion modules without having to modify the PLC program.
The first I/O module is always the CPU (8055i CNC without expansion board) or an axes board or
an I/O board (modular 8055 CNC). Note that this first module is not an expansion module.
In either case, the first input number is always I1 and the first output number O1 and they cannot
be set by parameters.
IMPORTANT: The numbering of both the first local input and the first local output of any expansion
module must be a multiple of 8 plus 1 (1+ 8n).
Inside the expansion module, the numbering of the rest of inputs/outputs will be sequential from the
first one on.
The inputs/outputs of the expansion modules will be numbered differently depending on the values
entered in parameters NUILOn and NUOLOn (with n= 1, 2, 3, 4).

If incoherent parameter settings are detected on power-up, an error message will be issued indicating
it.
