Full Maths & Script Processing
Note in this script above there is no way to reset the timer, this could be modified to allow
the user to reset this timer from a switch fed into a digital input as follows:
BLKV1=trun[1,0]; If it is then keep the timer running without resetting
return tget[1]; Return the current timer value
}
else If not then
{
BLKV1=tpause[1]; Pause the timer
return tget[1]; Return the current (paused) timer value
}
if(D1!=1) Tests if the DI 1 is not set
{ If it isn’t then
if (GLBV1==1) Tests if the global variable 1 is equal to channel 1
{
BLKV1=trun[1,0]; If it is then keep the timer running without resetting
return tget[1]; Return the current timer value
}
else
{ If not then
BLKV1=tpause[1];
return tget[1]; Pause the timer
} Return the current (paused) timer value
}
else If it is
{
BLKV1=treset[1]; reset the timer 1 to zero
return tget[1]; return the current (zeroed) timer value
}
