  1. Hi all. I'm looking to purchase a US7-B10-B1 as a test rig initially for learning Unistream (some experience with Visilogic already but want to dive into Unistream). No need for I/O or anything complex at this point. While I have done some programming, I'm extremely new to the hardware side of things so this will be painfully "noobish". That said, on with the mini project... I want (generally) to have the US7-B10-B1 in some sort minimal enclosure (10x8x4 ish?) with only notches for the HMI, power cord, and ethernet. Any thoughts/recommendations would be appreciated in regards to
  2. From Joe's explanation, the 4/20 with a 14 bit would round to 3277, but I'm asking if the value in the linear function should be -1 from that (3276)
  3. Thanks for the explanation / makes sense. As you said, probably never notice it in the real world, but then shouldn't the lower bound be 3276.8 - 1 = 3275.8, rounding to 3276 rather than 3277? Asking more for learning purposes than concern over nth level of degree accuracy of the RTD.
  4. My god... I actually understood that. Much thanks! This is how I had it set up when I left today but was unsure of it (aside from using 16383 vs 16384 for whatever reason), maybe just a typo. In my defense, the RTD and transmitter wasn't my choice, I'm' just the one trying to make the PLC like it.
  5. Greetings all. First round setting up a RTD and, after reviewing forum posts here, I believe I am more confused than before... but likely an easy answer for most around here as I'm much more of a software guy. Our setup: V700 Model with an RTD going to a IO-ATC8. I do not have the RTD model# on me at the moment (typing this after hours but can provide tomorrow) but I know that the RTD contains a Prosense XTH-0300F-PT1 transmitter (0-300 degree F even though the RTD itself is capable of a much larger but unneeded range) I understand that the IO-ATC8 is 14bit. The confusion:
  6. We have one a few of these and my only hurdle with it was power supply related. The instructions imply you can run off USB to PC, USB to power brick, "DC2.0", etc and rated 5-15v, 500mA. We tried all manners of common USB power bricks and it would flake out like crazy. Eventually used a travel adapter to dial it it and now it works perfectly. One would think it would pull in what it needs and be happy but, no, it was very picky to be stable. Since then, we bought a few VAP11G-500 (higher range model) and it requires 5.5-15v, 3A... Now to find an appropriate power supply so they too c
  7. Greetings all. We have started a minor project at work and we are, admittedly, pretty new to doing any sort of networked communications from PLC to PLC. We have 3x V700 currently and what we hope to accomplish is simply to have (perfect world) a full rendering of the remote HMIs on each of the PLC. Therefore, PLC A would have a link to go to PLC B's HMI and another link to go PLC C's and be able to see the HMI as if standing at that PLC - akin to the iOS remote operator app or using the Windows remote operator software. The question in the end is has this already been easily implemente
  8. We used one of these as well but found two issues : a) It didn't seem to get anywhere near the range and ended up buying the next model up for better range and b) To power it after initial setup in the PLC cabinet we tried to use a USB power brick which was very trial and error to get it to work. Initially tried a 1A and then a 2.1A. Neither worked although it should have been fine as long as it was 5-15v per the manual. In the end, we settled on a 6V 0.5A (since 0.5A is what traditional USB supplies anyways) DC adapter - fired up fine. Otherwise have been really happy with t
