  1. DL05/06 programming questions

    Thank you very much for all your responses, this is one of the best forum experiences I've ever had. I'm gonna rework my code or just restart all together and try and add in the few extra things I skipped over. The whole variable thing I was confused on is much clearer now after rung 7 was pointed out.... not sure how I didn't make the connection. I'm sure there will be more problems I'll seek out help for soon.. Thanks again for all the responses. -Jay

    milldrone, Thank you for taking the time to show me your version of my program, this gives me a new perspective and also shows how much more efficient I could be with my own code. I really like the way you changed the style of my alternation, my way seemed a little bass ackwards. I'm not entirely sure if I'm understanding how you make use of the variables though. I've always known that you have to first declare a variable, then you can set it to whatever you would need. DirectSOFT obviously already has preset variables declared for you, but how do you see where you "set" the variable? For example in your program, the sequencing timer uses V401, how am I able to actually see what value V401 (or any used variable) holds? EDIT: I also realized that I will need to have fixed intervals for when certain outputs actuate, but, will also need to be able to control the amount of time Y0 (heat station) stays on for. Would an appropriate solution be to use a math function and just use the same variable for all 3 outputs and adjust the amount added accordingly?

    I'm not too sure if I know what the difference between Inline/Offline thermoformers are. They are more orientated toward trays and larger single piece forming right? The thermoformers I'm involved with are mostly known as "linear rapid blow thermoformers". A continuous strip of plastic ranging in lengths of 10-400+ meters and widths of 8-88 mm. Think of like super 8mm film... only thicker polystyrene and with pockets.

    Everything should be labeled now... I hope its sufficient. thermoformer_edited.zip

    Sorry, I thought I had uploaded it in my last post, I didn't see the attach button. Thermoformer.zip

    Right now what I have works, the last output Y3 doesn't work properly since there's a sensor I need to get input from, but more of less the cycle is what I want. The other thing I'm going to have to add is a way for the user to control how long Y0 is closed for. Any type of direction would be most appreciated.

    Thank you for all the extra sites, no doubt they will come in handy. From the other posts it seems that I'm not trying a task that's completely out of reach for a first program. If I .zip all the files involved in the project and upload them would someone mind just taking a look to see if I'm going in the right direction with the program? I know what I did works so far, however, I'm not really sure if it's actually something that would work set up on a running thermo former. -Jay
  8. Hi everyone, I'm currently trying to learn programming for the DL05 using DirectSOFT5 and potentially the DL06 sometime in the future. The machine it will be used on is a type of thermo former, also known as a "blow form" thermo former. I've only been aware of PLCs for about a year so consider me a newbie to the PLC world. I've had a few courses and done some of my own computer programming so I know I'm pretty capable of grasping the concepts of programming. I'm practicing with the DL05 using 2 switches, 2 push buttons, and 4 lights for the output. I've written up a small program that basically does what I assume will take care of the first two stations of the machine (the heat station and form die/air which is what will form the plastic), however I'm not really sure if what I did is correct programming structure. I was hoping someone might be able to take a look at what I have done so far and let me know if I'm at least heading in the right direction. Any help or comments would be greatly appreciated. The machine I'm sort of trying to design off of has about 5 inputs and 17 outputs and uses a touch screen to get user information such as how long the heat station actuates for, setting the temperature for the heat station, and the count for how many times the machine will cycle. What I'm wondering, is just how advanced the programming will get for something like this? I've read a lot about what PLCs can do and it seems to me that this does not maximize on their capabilities. Would stage programming be necessary? -Jay
