  1. Major Tangent - Read at your own Risk

    We have all heard the rumor before about someone recieving a car that gets 50mpg when it should only get 20 and the dealer mysteriously tweaks the car and now it get's 20. Those stories are always he said she said. This was a quote from my previous post. Sorry my quoting didn't work correctly. Throughout my life from time to time I have heard people say that someone they know has bought a car in the past and the thing got an astronomical amount of mileage per gallon. I usually hear like 50-60 miles. Then they go to the dealer and tell them, which they immediately ask to see the car. When the customer recieves it back it magically only gets it's rated mileage. Now the best part is when you ask them who this person is so you can speak to them, it's always like their aunt's neighbor who recently moved to Antartica. Needless to say it can't be proven and I would like to think of it as an urban legend. Maybe I should report it to mythbusters. (Good show by the way)
  2. Major Tangent - Read at your own Risk

    About the big three, why is it over the last 10 years cars gas milage has for the most part remained the same? I definitely think they are tied to the oil companies. My 10 year old pickup gets the same gas milage as a new one. What if we sold service like this? Here, buy my product, but the only thing you are going to get is shiny paint and a comfortable operators chair. Production will remain the same. We would get kicked out of the owner's office before the second hand moved on our watch. I don't mean to offend anyone that works for the big three, I just wonder if they are giving us a trully advanced engine/drivetrain. We have all heard the rumor before about someone recieving a car that gets 50mpg when it should only get 20 and the dealer mysteriously tweaks the car and now it get's 20. Those stories are always he said she said. Enough rambling-how about that cold fusion. Well, maybe we should start with hydrogen.
  3. more data logging

    After reading Bob O post below about data logging I was wondering how far a person could take the information. We have an application where we would need to log and monitor a temperature for about 3 weeks. Then, at the end of cycle we would need to print out a graph of the period showing the 3 week trend. Is this possible with excel. For this would I need RSview32? I've never done much more than basic programming and I've never used RSview32 so I'm nervous about trying to tackle this. I really haven't used excel or access that much either since college and unfortunately my memory is fading. I have done some research on AB website about the plc pieces and parts I will need, but I dont feel confident about the data logging. I've looked at some of the downloads and they helped, but this really is my territory. OEM's over charge for this software setup and we would like to save the money. Any suggestions?
  4. Maximum RTD Distance

    Sorry Ken. I know I shouldn't hijack, but that thread really got my brain going about a possible project.
  5. Just to ask for my own knowledge without doing any research. Does anyone know the maximum wire length between the plc and the rtd. I've been thinking of doing something similar to this, but it's about 400' from the plc.
  6. I know this is a question for a different forum but here it goes. Everyday I get an email for someone about stocks or something like that. Normally their address looks something like this: jlskhah alhdaasdf@(somewhere).com So I block sender. Day after day. I know the reason why their name is jumbled is when they start a new address(daily I presume) they know someone doesn't have that name. So I goto somewhere.com and then I get redirected to what looks to be an innocent useful website. How do I get rid of these people. I dont want stock from someone with the name dshaoih aoihodf. Hello, was I born yesterday. Someone must buy it from them or they would be able to do it. Anyways, How do I figure out who's doing this? I wish I was a hacker. I'd----well you know!
  7. Time for my NOT training

    All of this I totally agree with. That is my question. I have a source from I:1.0 of 224. In binary, that would equal 11100000. So far so good. Now my destination is n7:3 and it says -225. That there is my question. Why does it say -225 when that is not true. It just not's the binary. Which is 00011111. I've followed the logic and that is what I have. So really I would not have a question if it did not say -225 in my destination. The binary is correct which is really all I should care about but I still have to know.
  8. I'll just tell the whole story. I have an encoder(BEI 256/Rev) connected to a 1746-ig-16-ttl input card with a 1747-L-514 5/01 processor. Oh by the way, I've never written a program with an encoder. I'm learning though. Anyways, the encoder count is taken and put as the source on a not function. At my home or starting position I have a count of 224. After it is NOT, the destination is -225. I'm assumming the count of zero is added hence the -225. So in binary 224 is 11100000. And it's inverse in binary then is 00011111. But thats not -225 in decimal. Right? Really that is my first question. I told everything about the encoder because I'm probably going to have more questions later. Although, without seeing the logic it might be hard for you to answer this, but why would you want to invert. I'm pretty sure all the other encoder logic I've seen uses the count straight. Just asking? I need to go work on something, but this is where I'll start.
  9. soft starts-the old way

    Camel, We even have soft starts on 7.5 hp motors. The main issue is burning the belts. A lot of our loads have high inertia. You could also look at it from the equipment point of view. It's a lot easier on a rollcase or chains or whatever if you start over 8 seconds versus 1.5 seconds. I hate to jinx myself, but we rarely have trouble. Knock on wood.
  10. soft starts-the old way

    The soft starts are on 30hp motors. They're not very big maybe 12x12, but you also have to add the contactor. I have been thinking pretty hard about vfd's. Really what it all boils down to is when one cooks, need fast replacement. That is why I'm sticking to finding the same thing I have. During down time, I'll probably replace some of them which will give me a larger stock. Camel, You got me thinking maybe we should start a new thread about where we send our parts to have them rebuilt. Unless it's already in the archives.
  11. soft starts-the old way

    Thanks for the replies. Tw I know about the smc-2. If I remember correctly the smc was the previous model. I didn't know they were still around. Camel, we do still get them repaired, but it is getting very expensive. I think we paid 500$ the last time. I just sent one off so I guess I'll find out for sure. When our line goes down it doesn't take much to justify the money but I do like the save when possible.
  12. We have about 50 old cutler hammer soft starts that became obsolete in 94 or 1995. Anyways they work day in and day out. We recently lost one and we do have a couple more in our stock. It's numbers are series A1 Model # 514-dnod . You still have your main starter contactor and then T1,2,&3 hook into the softstart. In turn, it's T1,2,&3 go to the motor. There is no control or auxilary power source. It only does time and torque. It's very simple, but efficient. Anyways the point of this is to ask if anyone makes anything like that anymore. I can't find anything. The reason I want to stick with the same concept for now is because we only lost 7 minutes changing out that starter. If I have to mess with control voltages and rewiring well that's going to take much longer. When I decide it's time for them to move on I'll probably change everyone so I get a significant price break. Just need a short term solution in case I for some reason run out of stock.
  13. TWControls avatar change

    TW Are you now a wolf in sheep's clothing? I don't know you, but I want to say thanks for all the good advice. I've learned a lot in here. Really that is for everyone, thanks for all the help.
  14. Vacuum application

    The cups I have seen on the internet don't look as strong as they sound. What if by chance I would get a product that was to heavy for the cups? When the machine pulled back is there a chance with the cup trying to pull the heavy product and it broke away is there enough suction to actually tear the cup or something of that nature?
  15. Vacuum application

    beu wolf, You mention to make sure to have enough dwell time. Here's my situation. A cant passes through a saw to make a board. After passing through the saw, two banks of chains pop up. One sends the cant to a set of chains to bring it back around to be sawn again. The board has two choice, to either follow the cant(this option is not used often) or to be sent futher down the line. What happens is if the board does not have a square edge it sometimes hits both chains that pop up. Since those chains are spinning in opposite directions it causes the board to spin 90 degrees until someone manually removes it. My idea is to have a set of vacuum cups to pop up and literally pull the board onto the chains a couple inches and then drop the board. At which time the cups would tuck back down. This could also happen above the chains we have room. My question is I probably only have 2 seconds to grab the board and move it. Is that enough time? I was thinking about 6 or 8 cups. That was the best I could describe it. I hope it's clear enough. Any and all suggestions are appreciated. By the way, a 16 ft. board is the longest board, 16 inches wide. At very most, they will weigh 50 lbs. max. I don't really know for sure but I would say an average board weighs around 15 to 20 lbs.
