  1. CNTX as a long timer

    Awesome, thanks! I had to put the C0002 in front of every timer at the beginning to stop everything otherwise I would still get the last two timers to give me signals in both directions in the end. Thanks Mr Oestreich!
  2. CNTX as a long timer

    I thought so but I am unsure of what address to use for the NC contact. You can see I tried using a coil attached to the CNTRX itself but it did nothing. I tried using 0002 as a contact but it just writes itself as I 0:02
  3. CNTX as a long timer

    I am using a CNTX as a long timer (at &14400) ~4 hrs. I have timers that alternate off and on for 8 seconds a piece, but after the 4 hours I want to completely stop all timing functions. The manual says something about a completion flag, but I dont quite understand what that is, or how I can use that as an input or output. I know that when the CNTX reaches zero, it highlights itself in green and stops counting. right now i have the CNTX set at 40 seconds for testing. I am using a one second pulse for counting.

  4. Friends, I have a CP1H 40-xa-dt monitoring and positioning a hydraulic cylinder. The HMI I am using is a NB5Q. As of right now, LVDT position is wired directly to a Parker BD98A servo card which looks for input voltage with respect to the positive and negative terminals to determine output in positive/negative direction. (eg. positive voltage on IN6 vs IN7 provides positive current on OUT1 vs OUT2, positive voltage on IN7 vs IN6 provides positive current on OUT2 vs OUT1). My Issue is that the LVDT only operates in a positive voltage direction. I've wired up a relay to switch the wired terminals as an experiment and it works, but the LVDT voltage goes from a maximum positive to a maximum negative voltage to input terminals and the cylinder slams retracted. I know the CP1H can be scaled -10 to 10vdc on the D/A terminals. Could a SINE function be used so the cylinder will follow sine wave and extend while riding the curve in positive direction and retract once sine wave is below 0 in the negative direction? If this is possible can i control the speed of operation, like using an increment function? The cylinder is only being tested for operation for a certain amount of time to ensure no leaks after rebuild. I am a bit new to this. Regards, Thor
  5. cp1h analog to digital and back again

    that FB really helped, thanks! New question. I finally got my servo valve to work (long story short, motor was wired backwards and no pressure). My Input to my FB and servo card reads 0-10 volts, but the servo card output needs a + and - to drive in different directions. So far I can drive it down, but have to shut it down and reverse signal wires to drive back up again. Is there a function block or parameter i can change that will give me a negative voltage output?

  6. cp1h analog to digital and back again

    which one do I hook up the outputs to on the FB? I made it just like your example, but should it go to a MOV for the output? If so, is it the INT or WORD one?
  7. cp1h analog to digital and back again

    How do I make that function block? I've never made a FB before. Or is there one premade in CX-Programmer? I have the CX-lite version for this CP1H
  8. cp1h analog to digital and back again

    Thanks, that helped. What type of function do i use to interpret the analog signal? it is 0-10vdc
  9. Hello, im new to this forum. I've been messing around with OMRON plcs for 5 or 6 years, but never fully made a program from scratch. I'm using a CP1H-XA-40 (relay input/output). I cant quite seem to figure out what the actual input addresses are. I figured out that the outputs are Q100.00 and so on, but that's all ive gotten so far. I am trying to use a NB5W HMI screen to communicate when to program is finished but I never used NB designer at all, and frankly I dont know what im doing there either. I've been tasked to use the plc mentioned above to operate a hydraulic test stand. I have all the wiring completed. As far as the analog to digital, I have two inputs both 0-10vdc. I dont know what bit to use for these. Same for the outputs. Any help is greatly appreciated! Thor
