Macro variable selection signal
EVAR <G251#5>
[Classification] Input signal
[Function] When this signal turns to “1”, the CNC acts as follows.
・Selects macro variables as I/O data.
・Inputting operation
Macro variable data is input from the I/O device.
Input condition: Set protection signal KEY2 to 1 (only when
bit 7 (KEY) of parameter No. 3290 is set to 0).
(NOTE) Macro variable data can be entered by background
processing of an external I/O device control only in the
data output format specified with bit 2 (VFP) of parameter
No. 6001 set to 1.
However, it is impossible to input or output an absolute value
exceeding 99999999.
When VFP (bit 2 of parameter No. 6001) is set to 1, the required
tape format is as follows:
P# macro variable number Q data ;
P# : A three-digit number that follows P# is a macro variable
number.
Q : A value that follows Q is data. (a decimal point
can be included).
Space : Blank data
0 : Data 0 or overflow/underflow data
Example)

P#500 Q0 ;
P#501 Q1.000 ;
P#502 Q10000000.;
P#503 Q-0.0000001 ;
P#504 Q0 ;
P#505 Q ;
