Our UR 10 has a programme that controls  4 different welding Jigs. When a jig is loaded with a product it triggers a Digital input. If a Jig is not loaded and the input stays low, is there a command I can use so the programme can skip or jump further down the programme missing this Jig out. If so how can it be programmed ?

    Put your code inside and if statement, then if the of statement is not made it will skip to the next section. 

    If(digital-in-0 == True):
      do sometbing
    if (digital-in-1 == True):
      do something
    .... you can also write the if statement like this 
    if (digital-in-2):
      do something else

    Mathew, I tried it today on my programme and I could not get it to work. 
    This is a programme I have found online, similar to ours, what I would want to input into the programme  before the first Move J, basically if DI 0 is high continue the programme as normal, but if DI 0 is low go straight to "Pick sequence" and skip waypoint 1 + 13

    How would the code look for this please, and where would it be inserted ?

    further to my last image, this is the actual programme we run, Start 2 is connected to a proximity switch that goes high when a part is loaded. What I am trying to do is skip Jig 1 if no part is loaded and go straight to Jig 2. 
    I have made the "If" statement 4th line down, " If start 2  is False "  but do not know what to put into the next line if the criteria is met, to skip straight to Jig 2 in the programme.
    What function or what to input to make it happen ? 
    Anybody able to help ?

    Put your entire Jig_1 folder under the if statement. Then if that sensor is high it will execute Jig_1 code. Then put another if statement for Jig_2 and place it under that if statement. 

    I’m not near a robot at the moment but basically this

    If (DI0):
    if (DI1)

    Yes Matt, running perfectly now, just cut and pasted the folder with each jig under the IF command and set the IF D!1 = true then Jig 1. and so on. thank you very much. I was going to post it later on to let you know. 

    The next step in the programme is to set a counter so after every  50 or so cycles the programme then moves the TCP to a point where the welding nozzle can be cleaned and a pop up appears on the screen to execute then restarts the programme and re sets the counter. I dont suppose you can give me any pointers on this please ?

    Create an installation variable on the installation tab and set the initial value to 0. You can then use the set command, at the bottom you can increment an installation variable. Do this at the bottom of your program. Then after you increment it use an if statement and check to see if it’s whatever you want to move to the cleaning station. Once you do that use an assignment and select that variable from the list and set it to 0. 

    The reason to use an installation variable is so that the value is persisted across programs starts and stops as well as powering the robot off and on.
