  1. wireless start stop

    i have a 12 channel device in my home i use for various functions, door locks, lights, etc., the relay board is wired directly to the plc and the transmitter (smaller than a credit card) runs on a AAA battery. it works great. check ebay thats where i bought mine for like $20 american.
  2. electric vehicle help

    I have a EV project i have been playing with for a little over a year now, but now comes the time when i need to start wiring for my plc. (yes i said plc) I have a compact logix and a panelview 700 to put in but i am new to both of these. what i need to know is this. what cards do i need to monitor dc voltage from 12 to 50 volts with a compact logix? is it possible? my plc is just a processor and 1 input and 1 output card. money is very tight as of lately so my purchasing has stopped for now but i would like to get an idea of what i need to get later. any help or cool ideas to use it for is appreciated

  5. web site

    hi guys. i want to build a website with a forum similar to what mrplc is (but i would like to do one on free energy). can anyone tell me what softwares i will need and maybe a few good study books. i am intermediate at programming so it shouldn't take me long to pick it up i just dont know where to start. i already have a server i bought off ebay. i think i will have to get some changes done with my isp so that my ip adress will stay the same. Nathan and Chris you guys got any suggestions (being you 2 are like walking encyclopedias). thanks a million
  6. Red Lions PLC and HMI

    well to put my $.02 in, our company has been testing quite a few of the redlion g310's. We are quite impressed with them. Everyone is sick to death with the atmosphere of Rockwell. I am not high enough up to be able to say for sure but it looks like all of our HMI's are being changed over to Redlion as they go bad. All people i have spoken to in our company is impressed with the performance,reliability, and customer service that Redlion has. i myself am pushing ,from a troubleshooters stand point, for the switch to Redlion because i was able to download the software FREE on my home computer, as well as documents, without an act from congress and the president. This allows me to have time to better learn the software and experiment at home, comms are much easier to deal with as well as programming. From me Redlion gets two thumbs up! Rockwell two thumbs down
  7. web site

    nothing illegal Nathan.my site will be on using solar wind and water. converting gas vehicles to electric and things of that nature. I will look in to the sites you guys mention , however I would like to have it run from my house (on solar power) as part of the theme of the site. and I prefer not to have to answer to another company. but due to costs I will have to look at all options. thanks guys

  12. slc 5/04 bit shift

    sounds like you have dealt with this Bob, any tid bits on how to get started? never written anything close to this type logic i think if i had a small sample i could probably figure out how to go from there. thanks
  13. slc 5/04 bit shift

    hello folks, i have a question as to whether or not a BSR would be appropriate for a load queue. what i have is a generator controled by a slc 5 04. the total load is roughly twice the size of the generator. so what i have come up with is using intergers and math instructions to calculate how much wattage is actually being used and how much is left and bring in other loads when one drops out that doent exceed the wattage thats left and hold off all other loads. could i use some type of bit shift to create a queue to sort of create a first come first serve type deal? timing is not critical so if one has to wait a while it is not a problem i just dont want the larger loads hogging the hole thing all the time i want to be fair and give everything a turn so to speak. if this sounds like it might work how would the rungs be written? thanks , david
  14. Internet Explorer 7

    i had IE 7 on 3 computers and it made various things not work or crash so i uninstalled it on all of them. hopefully with the error reports i sent they can fix it all soon and i may try it again later. hope everyone else has better luck
