19.1 Inputting/Outputting Data
The main CPU memorized the following data.
Outputting the data I/O device while the CNC is running normally
(1) CNC parameter
(2) PMC parameter
(3) Pitch error compensation amount
(4) Custom macro variable values
(5) Tool compensation amount
(6) Part program (machining program, custom macro program)
19.1.1 Parameters required for data input/output
NOTE Note that data may not be output in the alarm state.
Parameters required for input/output are as follows :
In addition, l indicates the standard setting for input/output devices made
by FANUC. Change these settings according to the unit you actually use.
(Parameter can be changed in MDI mode or emergency stop status.)
#7
#6 #5 #4 #3 #2 #1 #0
0000
ISO
#1 (ISO) 0 : Output with EIA code
1 :Output with ISO code (FANUC cassette)
0020
Selection of I/O channel
l 0 :Channel 1 (JD36A of mother board)
1 :Channel 1 (JD36A of mother board)
2 :Channel 2 (JD36B of mother board)
3 : Channel 3 (JD38A of serial communication board)
4 :Memory card interface
NOTE An operation example shown here assumes that data input/output
is performed with an input/output unit connected to the JD36A. (I/O
channel = 0)
#7
#6 #5 #4 #3 #2 #1 #0
0101
NFD ASI SB2
#0 (SB2) 0 : No. of stop bits is 1.
l 1 :No. of stop bits is 2.
#3 (ASI)l 0 : EIA or ISO code is used for input/output data.
1 :ASCII code is used.
#7 (NFD) 0 : Feed is output when data is output.
1 :Feed is not output when data is output.
