V variables
The MANUALplus uses value ranges to define the following scope of
variables:
„ Real: V1 .. V199
„ Integer: V200 .. V299
„ Reserved: V300 .. V900
Requests and assignments:
„ Read/write machine dimensions (machine parameter 7)
Syntax: V{Mx[y]}
„ Interrogate external events
Is the bit value 0 or 1? The significance of the external event is
determined by the machine manufacturer.
Syntax: V{Ex[y]}
„ Interrogate sequential events
The tool life monitoring function and the function for searching the
start block trigger sequential events.
Syntax:V{Ex[1]}
„ Read/write tool compensation
Syntax: V{Dx[y]}
Example: "V variable"
. . .
N.. V{M1[Z]=300} [ sets "machine
dimension 1 Z" to "300" ]
. . .
N.. G0 Z{M1[Z]} [ moves to "machine
dimension 1 Z" ]
. . .
N.. IF{E1[1]==0} [ Interrogates "external
event 1 – bit 1“ ]
. . .
N.. V{D5[X]=1.3} [ set "compensation X for
tool 5" ]
. . .
N.. V{V12=17.4}
N.. V{V12=V12+1}
N.. G1 X{V12}
. . .
x = dimension 1..9
y = coordinate: X, Y, Z, U, V, W, A, B or C
x = slide 1
y = bit: 1..16
x = event: 20, 90
„ 20: Life of this tool has expired (global information)
„ 90: Define start block (0=not active; 1=active)
x = T number
y = length compensation: X, Y, or Z
