  1. Hello all, I have an application in which I need to control six different stepper motors. I also need about 16 each DI and DO. Can anyone suggest a hardware combination that will work well and be the most economical? I would like to use the Vision series controller, preferably the 570, but I am open for other suggestions. Many Thanks!!
  2. Thank you Mr Pratt. This is very helpful.
  3. Hello, I think what I am going to use for this will be the V570 with the snap in V200-18-E62B and an EXF-RC15. It seems this combination gives me 6 PTO's, all the local I/O I require, and spare I/O via the EXF-RC15 high speed remote I/O module. I am not sure exactly which stepper motors I need yet but I do know I want the control to be accomplished using the V570 and the remote I/O module.
  4. I had the identical application a few years back... I used the photoeye to see the beginning of the carton, and an encoder to count pulses generated by the conveyor movement. I had to use the encoder because the carton size differences were very slight. This worked great even if the conveyor speed changed.
  5. Hi All, I am using a V430-J-TA24, Hardware rev B, OS 4.0 (19) with Visilogic VER 9.9.2 build 0. My issue for today is that the ascii key pad entry screen appears, but it is not centered in the screen. It is centered too far to the right and as a result, the screen wraps around and continues on the left hand side of the display. If I could shift the whole screen to the left, it would fix the issue. I know there is an x and y setting SI 245 and 246, but it says this is for the 1020 model.... Any suggestions on how to correct this? Thanks once again
  6. Just an FYI...... I had to upgrade the OS for the controller and that was the correct fix.
  7. Hi All I just got the alarms programmed in and it works fine except for one thing... the trigger MB is set for "on" . The only way the alarm details screen pops up is when the trigger goes high, then low, then high. Basically, the trigger has to go high twice to activate the pop up screen. After acknowledge, the alarm works properly. Any thoughts? Thanks
  8. Hello all, Does anyone have the example load cell example application that comes with the visilogic software? I do not have the install disc as I downloaded it from the Unitronics site. Thanks!
  9. Once again, I thank you for your help. My application is up and running!
  10. Thank you Alex. I did locate the example. Can you tell me how to convert the example to a V430?
  11. Can someone post the load cell example for me? My visilogics software does not have the file. Thanks.
  12. I have done this before and it worked out great for the process I was programming. I call it the "Poor Mans PID"

  14. Hi all I am new to the Visilogic PLC platform and I have a PID question. A little background on myself: I have been using Allen Bradley / Rockwell products for the last 25 years and it is now time to change to a new platform. The company that I work for will not buy in to the licence fees associated with their products, so here we are trying out Unilogics products. My first project is a heat tunnel application using a V570-57-T20B controller. I also plan on using a snap in I/O module to allow the use of a type J thermocouple. My question is this: I have set up the PID FB configuration. No problem. Now I want to incorporate the auto tune FB for the same PID loop. Must I configure the Auto Tune FB since the PID FB is configured? If so, do I use the same MI and MB in both configurations, or does the Auto Tune FB configuration need to have it's own MI and MB's? It seems to me that they would both need to use the same memory addresses. I have read through the manuals that I could find and watched a few vids on Youtube and I suspect that these are using older software revs. Also, do I really need to have the snap in I/O? There is enough I/O on the controller for this application. If I can use my J thermocouple some way without having to buy the snap in I/O, that would save me some bucks. My hardware is on order and not here yet and I have nothing to download to and experiment with. I have enjoyed using the Visilogic software so far. Thanks
  15. Thank you for the advice, Alexander. I will let you know how the project turned out.
