  1. Have you tried just using a limit instruction?
  2. Took this course 7 years ago, and I still reference the course books. That has proven useful. The course itself, I would have been better off, for myself, to have just purchased the books. But I learn better by just trying and failing, and trying again, rather than listening to someone talk and run PowerPoint.
  3. WIFI Communication to RIO

    Mel, what would I be looking at at that site?
  4. So, I was wondering if this scenario is possible. And I apologize for the crude drawing, but art was never my foray. I can run hard cable out to the out buildings, but I really was thinking maybe I could just do it through WIFI. Any suggestions? I was thinking maybe something like this would work, but I really don't know. WIFI Config..dib
  5. AB MicroLogix 1200 Backup

    The very sad part about this is, 1) You have to buy RSLogix500, 2) You have to buy the proper cables and adapters, 3) You will not get the labels for the program, so your just going to see the logic, without any easy way to figure out what you are looking at.(unless you are a genius, unlike me) Most laptops nowadays will not have a serial port, so you have to have a USB to serial adapter. Contact the manufacturer of the equipment, and ask them for a copy of the .rss file. Some company's will require you to sign a non-share agreement before they give it to you. As I explain to them, (although I always sign it anyways) we own the equipment, ALL OF THE EQUIPMENT, so we need it for maintenance. Again, just my two cents, coming from the maintenance side of this type of problem.
  6. One way to do this would be to position Prox. switches along your travel, and start and stop the cylinder. This would also require that you  use a center off, or center hold valve, and while not perfect, it would work with out having to use a more expensive linear slide. But a linear slide would give you a much more positive positioning opinion. Just my maintenance man opinion.
  7. SInk plc input module

    I cheat, I tell the people I hire the difference between sinking and sourcing is kind of simple. And if they look at the machine wiring prints, follow out which wire they are switching. PNP = It switches the positive circuit...PNP NPN = It switches the negative circuit....NPN I know this is simplistic, but for the non-engineers, it's easier to follow.
  8. Gentlemen: I am so confused. I have tried to figure this out, and I am still lost. Using a 1734-IT2C and Type K thermo., I can not get the numbers right. So, would someone please tell me where I am so screwed up on this?   I have been struggling with this for a month now! Thanks: Scott
  9. Taking Screen shots

    So, Green shot, and the snip-it tools both work! Thanks for replying! Scott
  10. Another Dumb newb question

    Just so we all understand,  I put the thermocouple in a glass of ice water, and the thermometer reads 32, but trying to use those engineering numbers, my actual value was -480 degrees, so I played with the min and max inputs till it read 32 at those values. If I put in the 0-7000 values, I really have no idea what my scaled min and max should be set at. A type K thermo ranges from -270c to 1370c or -454 - 2300f. And that didn't work. The 1734-IT2I is configured just as pictured in Joe's screen shot. Again, thanks for reading and replying! Scott
  11. Another Dumb newb question

    J, nothing secret about it. I am monitoring thermo-couples, based on outside and inside heat, and turning a heater on in a shed, just to keep it from freezing everything up again. I am however, adding this to an existing program, and using RIO. Just being geeky! I am a maint. electrician at work, and have to troubleshoot all the PLC issues there, and so at home, I play/practice with the programs and hardware. (i know, get a real hobby) When I first got started with this stuff, I used RSLogix500, and it, to me, seemed pretty easy then. So, I just puttered and plinked around with it. Now, I have to be better at the troubleshooting, so I am trying to expand into the more difficult stuff, and boy, what an eye opener! But I sure do like the help I get from all of you here on this forum. Scott
  12. Another Dumb newb question

    So, Gentlemen. Can anyone tell me just what I have wrong here? Scott.
  13. Another Dumb newb question

    Andrew, I will, just as soon as I figure out a way to take a screen shot. I'm downloading Greenshot now. Wish me luck? Scott
  14. Taking Screen shots

    Thanks all, I will look for Greenshot. Scott
  15. So.... a lot of you on this forum seem to know how to do this, so I am going to ask here. How do you take a screen shot, and then post it so I can explain easier what I am struggling with? Thanks: Scott
