18.8 Touch probe interrupt processing
Crates are transported to a filling station on a timing belt. A proximity sensor (DI02) de-
tects when the next crate arrives. This triggers an interrupt and the belt moves a speci-
fied remaining distance. The crate is then positioned directly under the filling station.
Once the crate has been filled a new cycle is started.
Input DI10 must be active during the entire cycle. If DI10 = 0, the timing belt stops sub-
ject to position control. When the drive is restarted (DI10 = 1) it completes the cycle.
The position values, ramp and speed are entered in the variables H11 ... H14.
// Main program loop
while(1)
{
if( DI17 )
{
Data_Var1 = 222222;
Data_Var2 = 444444;
}
else
Data_Var1 = 111111;
{
Data_Var2 = 222222;
}
}
}
Variable Name Description
H11 TP_Max_Pos Maximum target position if the touch probe input is not attenuated
H12 TP_Pos Remaining travel after the touch probe input has been attenuated.
H13 Speed Positioning speed in rpm.
H14 Ramp Positioning ramp in ms.
