  1. Thank you @kratmel and @Ausman All good. I will tell you that organic chemistry is wayyyyy easier than getting a handle on some of this stuff.
  2. Hi Kratmel, The model for the one I picked is https://www.automationdirect.com/adc/shopping/catalog/field_i-z-o/stride_i-z-o/analog_i-z-o/sio-mb08ads-1 . Is there an example code anyplace that I can look at? @Ausman The myth, the man the legend. I was able to configure the remote I/O via its built in web server. I am just not sure how to call the values. Thanks All
  3. I am new to trying remote I/O. All the documentation from Unitronics revolves around their URB-TCP modules. Can I use an aftermarket remote I/O such as the stride analog module? If so, can someone point me to a manual for setting up an aftermarket I/O. I was able to set the IP for the vision and the IP for the I/O, but I don't know how to read the I/O. Thanks
  4. Are you using a unitronics brand cable or just a standard network cable? You must use the unitronics cable.
  5. In my limited experience I have had similar issues. things to check/try. Even though your power supply is 24 VDC it may not be large enough. Try a higher watt supply and a quality one. Check how close your thermocouple wire is to motor leads. Grounds, grounds, grounds. We earth ground every tank, isolated pipe, panels, etc. if it’s metal... earth it. good luck
  6. When the issue fist happened it was when I started using the IO that I had installed at the beginning for later expansion. My first thought was the power supply so I switched it out, this made no change. When I woke up at 2:30 am and saw the message from Kratmel who said power supply again, I started to think about it more. I remembered that I added 2 relays and 4 solenoids. Then I knew; I maxed out the power supply. Pulling the 1.5 that was in it and putting in a 5 amp not only solved that problem but it also solved all the issues I was having with my 4-20mA sensors that had intermittent wild fluctuations. Looking back, the heaters were not always on. When they were, those were contactors pulling higher currents so my sensors were starved. I never placed all these issues together to blame the undersized power supply.
  7. Here is what fixed it for future reference As I woke up at 3 am, I saw that @kratmel emailed me a check list. #4 on his list said power supply. I dismissed that one because I switched them out earlier that day to test that. The more I laid there, I figured there had to be something to that or he would not have wrote it. Then it hit me, I added to more solenoids and two relays to the panel, and I had a 1.5 amp power supply. I came in this morning and tossed a 5.0 amp power supply in it. BOOM! not only did that fix my input issue is also fixed my wildly floating sensor readings. Future reference to all. Is your power supply large enough. You may have done a spreadsheet, like I do that says yes, but go BIG or go home. Thanks Kratmel, you put me on the right track. ps. thanks @Cam I have been there switching pins in the past, that normally fixes issues.
  8. I have all lights lit up as if they are all on. I wired it PNP. If I remove the 0V they all go off and I put +24 into an input they all are at state 1 not just the input I energized. If I have the 0V in all the lights are lit and every input is at state 1. If I energize and input have go to state 0 the other half stays at 1.
  9. No but you only have so many outputs. It just seems to get overwhelming and confusing have multiple coils calling one Output coil.
  10. It sounds like he is doing something similar to me. In my mind subroutines seem so organized, but the more I read ,the more they seem like a pain in the aperture within the gluteal folds of ladder logic
  11. Say you have a 3 screens/modes, Manual, Semi and Automatic. 1) Would it be kosher to have a sub routine strictly to that screen/mode in focus to save scan time? 2) Under that circumstance would it still be bad practice to reuse coils that were in another routine even though they cant be called at the same time? 3) I would fear doing what I am saying would leave coils set when you change screens. I would have to write one long line of resets upon leaving? Thanks in advance.
  12. I was trying to remember Joe's name as I was writing. WITHOUT A DOUBT @Joe Tauser! Although he has a grumpy look in his avatar, I hope that we bring a smile to his face
  13. This was a unit I had on my desk for testing/learning. It's a couple of years old.
  14. 3 years ago I knew nothing about PLC's. Because of people like @Ausman, @Flex727, @Joe Tauser and others on this forum, we converted 8 machines from old relay logic to PLC's with automation, made 2 pieces of complex laboratory test equipment for the lab, and entire tank farm controls that include, levels, filling, heating/cooling, mixing etc. I could have never done it with their help. I don't know if they're paid or not, but I will tell you they are priceless. I hope that @Cara Bereck Levy will show this to the powers at be so they understand the caliber of people they have in this forum. It burns me, me when people are rude or "expect" someone to write their programs without giving it any effort first. Be polite, give it your best effort and people here will jump in to help you. This concludes my diatribe.
