Use timer with 5.9 polyscope

tom24 2020-10-12

the Hass send signal to the robot two times with one signal M100. the first signal stay as input to the robot for 1 second and the second will stay for 3 second . so if i need only the second signal how i can use the timer. i tested may times but it is not work. i appreciated for the help
for instance i use like this before start
time=0
timer=false
main program
if DIO =true and time=1 sec
timer=false
else DIO=true and timer =3 sec

The easier way I'm seeing to do it is to use some loop and delay. Maybe something like this:

I tested with this program but not work

I would use a background thread to monitor for that input

thread monitorInput():
  local timer1 = False
  local timer2 = False
  while (true):
    local time = 0
    while (DI0):
     time = time + 0.002
     sync()
    end
    if (time = > 1 and time < 1.5):
      timer1 = True
    elif(time = > 3):
      timer2 = True
    end
    sync()
  end
end

This way in your main code you can simply wait for the timer1 or timer2 to go to True, also does it stay high for exactly 1 second or 3 seconds or is there any variability? You may need to monitor the state of time and see if sometimes it's slightly less than 1 or 3 for example.

Also, once you get the timer1 or timer2 True condition you will need to reset them as the thread will not reset or else the main program will not have time to use them. YOu cold also add a wait statement at the end so that the code simply waits for the input to go high again and then resets the flags and goes back to the top of the loop, something like this.

thread monitorInput():
  local timer1 = False
  local timer2 = False
  while (true):
    local time = 0
    while (DI0):
     time = time + 0.002
     sync()
    end
    if (time = > 1 and time < 1.5):
      timer1 = True
    elif(time = > 3):
      timer2 = True
    end
    while (not DI0):
     sync()
    end
    timer1 = False
    timer2 = False
  end
end

I tested but it shows me an error on the following lines script
if (time=> 1 and time < 1.5)
elif(time => 3):<br> timer2=true

matthewd92 2020-10-14

It’s the formatting on the forum

should read

if (time >= 1 and time <1.5 ):

if (time >= 3):
timer2 =True

still the same issue i have with the same line

matthewd92 2020-10-14

Can you post up your actual code. Hard to tell what the issue is.

tom24 2020-10-15

i tried but i have the issue to attach the screenshot
it shows me Lexer exception on line 6446: if(time>=1 & timer-1<1.5)

You have a typo in that line

if(time>=1 and time<1.5):

cannot use & and your second conditional is timer-1 which if that is how you typed it is a Boolean, you want time there

the script is working with out error but not trace as background to the main program i have.

The issue i have is with Machine A.

One machine will very briefly will send voltage to the end of cycle causing the robot to head to that CNC per the program.

looks at that input and waits for the input to be HI (ON) for more than 2 seconds. This would alleviate that millisecond signal we are seeing, being interpreted as end of cycle. this is while running the machine A. so, can you check the following program if it fix the problem

Doosan_MB running=false

Main Program

Loop

if Doosan_Ma=True and start=true .............(Machine A)

Doosan_MA_Running=True

statrt=false

Do acction

Doosan_MA_Running=False

if Doosan_MB=True .................................(Machine B)

Doosan_MA_Running=True

Do acction

Doosan_MA_Running=False

Else

waite=0.01

Thread

MA_End_Cycle=True and Doosan-MA Running=false

Doosan_MA_Running=True

Elseiif timer_1=True

Doosan_MA_Running=True

MB_End_Cycle=True and Doosan-MB_ Running=false

Doosan_MB_Running=True

Thread

if timer_1>=2

timer_stop

start =true

sync()

Event DIO=true

timer_1 start

sync()

Thread

thread monitorInput():

local timer_1 = False

while (true):

local time = 0

while (DI0):

time = time + 0.002

sync()

end

if (time >=1 and time &< 2):

timer_1 = True

end

while (not DI0):

sync()

end

timer_1 = False

end
