  1. Of all the stupid issues, yup that was it. Everything is working now! Thank you guys so much for the assistance.
  2. Okay so as an update, the inputs now seem to be correct (I just took all the jumpers out and redid them, I think J3 was actually the issue cause it wasn't in its default state) but now the linearization is not giving me the numbers that I want it to. The input numbers are within the range and aren't wavering at all, but the output is not what I would expect it to be. Also after the reset the big negative numbers did not go away. Edit - Wait I lied ignore the negative number comment, I realize I didn't actually reset it. Those are now gone but everything else is the same.
  3. This is it when it is online. The 3 on there is bouncing between 0-4 every cycle, but that isn't a value it should be getting. And the 2 large negative numbers in the unused MI's make no sense to me. I have the Inputs set up as such...
  4. Okay, so in my haste to get it set up I seem to have forgotten the 250ohm resistor. If that doesn't cause it to be correct then I will try these suggestions and get back to you guys. We ran them over the weekend as per the instructions on the sensors, so hopefully they should be stable when I test them again. Thanks for all the help though, definitely a little out of my element with these so it's a learning experience.
  5. So I'm probably not going to actually help but I know for accounts and passwords I've dealt with in the past it's always a space at the end, you could try that.
  6. So I have the inputs and outputs all sorted, but the input coming from the sensor is reading as 1024 for sensor A and 0 for sensor B which doesn't seem to make any sense. The sensor is in a pH buffer of 4, but it also stays at exactly 1024/0, which seems off because it should fluctuate at least slightly. Edit - Added pictures to see if it's something obvious that I'm just missing. I have it set to the 10bit numbers because I'm just using the onboard analog inputs of the V350-35-r34. The wiring is: Sensor ---> Pathfinder Transmitter ---> + (Power Supply) - (PLC Analog Input) GND (GND) http://pathfinderinstruments.com/ph/orp-transmitters/pathfinder-emit-ph/ http://pathfinderinstruments.com/ph/orp-transmitters/pathfinder-emit-orp/ Transmitters in question.
  7. You were correct in that it has a transmitter between it and the PLC. https://sensorex.com/docs/instructions/InstrTX100.pdf
  8. Okay so I do have a follow-up question. The sensor that I'm using measures ORP and pH, how do I differentiate the two when it's only 1 input?
  9. Thank you so much Joe, that all makes sense. I was on the cusp of some of those but that would have taken me quite a bit to get to that conclusion on my own. I'll update this if there's any issues that arise.
  10. So after a bunch of trial and error I'm happy to say I've made some good progress on teaching myself how to program decently complex things, but a few things elude me so hopefully the questions I have aren't too obvious. 1. I have 2 sensors that I need to hook up to the PLC and I'm having trouble figuring out exactly what I need to do for it, I've looked up some posts on here about it but none of them seem to apply. It's a 4-20mA analog input that reads pH levels, but I'm not exactly sure what the linearization inputs (X1, Y1, X2, Y2, Y) should be. If there's a guide or example program about that all I need is a point in the right direction. This is the sensor we have - https://www.sensorex.com/docs/specs/SpecsS600Inline.pdf 2. Is there any way to make a timer that counts up? I came up with a convoluted way of doing that using a timer set at max time and subtracting it from that number, but I feel like there's a simpler way to do that I'm missing. 3. For sending an email through a PLC is an SD card required? The example program (Joe Tauser's) that I got from here has inputs for the email text and all of that and it seems to hold all the information I need to put on it so can I not use the SD card in that case? Thanks for the assistance, if there's any other information I can send that would be helpful just let me know.
  11. Okay, that makes sense. Yea the $25 shipping was my main hang-up. Thanks for the assistance, I'll call them up and see what I can find out.
  12. I'm currently in the process of trying to order the V100-17-ET2 ethernet card but I'm having some issues figuring out the prices and availability of it. The main site that I thought to look was MotionUSA and of all the ones that I've checked (M.A.Selmon, Colterlec, and Radwell being the other main ones), it did have the cheapest price at $86 base with $25 shipping added to it which seems a little ridiculous for what it is. I guess my main question is does this price make sense, and if not is there a better source I should be trying or an alternate card that would work with the V350 that my work uses. Thanks ahead of time, -Chris
  13. So I'm currently in the process of adapting an old program to fit our current needs for my work, but after adding things to it it's giving me an error saying there are 18 fonts when only 15 are allowed. I've manually gone through and counted and there are only 3 that I can see, but I'm at a loss as to how to go from here. Is there any quick fix to this or am I going to have to redo the HMI completely?
  14. Okay, I was just trying to get a handle on how much of that program I could use for my specific need and what I had to change, its good to know I don't have to tweak that too much. Thanks again.
