Hi thinking about this mig welder. http://www.harborfreight.com/180-amp-migflux-wire-feed-welder-68886-8508.html
interesting to ask for example if PLC output 0-10 V DC and that voltage should control wire feed--- 0V DC correspond 0 feed and 10V DC correspond to 100% of feed -- complete revolution of knob -- that control feed of wire. what are there option available -- what device i can use to do that? want to find something -- solenoid etc-- rotational device that will turn the knob. like to put small gear instead of know and rug -- that can engage gear and turn it. Idea is that PLC will read current from spark and that will feed back about how fast/slow wire feed should be thanks aram On Tue, Aug 5, 2014 at 1:47 AM, alex chiosso <[email protected]> wrote: > Hi Aram. > As I suggest to you , IMHO the best way to interface Classic Ladder stand > alone with the field IO is Modbus. > You can find a lot of industrial grade hardware that will work with ( > Advantech > < > http://www.advantechdirect.com/eMarketingPrograms/L021113P1%20Sensor/ADAM4000_page.htm > > > Modbus Serial Line IO Modules , Advantech > < > http://www.advantech.com/products/GF-5TZ5/ADAM-4572/mod_1e01192d-95a1-42a4-b199-79343134f4ca.aspx > > > Modbus TCP/IP Gateway). > I prefer to use Modbus TCP/IP because of ethernet cables easy to have and > because of speed for refreshing the IO image. > You can use also the parport with a breadboard but I never tried it . > I don't think there is a limitation for the number of ladder rungs you can > edit. > Maybe is a configuration matter but onestly I don't know. > At the moment I'm not at my office so I can't check it for you .
