  1. here"s a little "Modbus Checker" program that I use with a V120 for testing Modbus controls to A-B powerflex VFD's You can dissect this and see how the Modbus is done in Vision Of course there are some hardware settings also, you must set the jumpers in the V120 to make port-2 RS485 and set the powerflex to run on modbus you will also need a cable going from RJ-11 to RJ-45 I don't have the pin-out in front of me but I'm sure it's easy to find...

  2. This is interesting, as I have been running like this for several years without issue. I copy the entire DataXport folder and rename it. It seems more that something has corrupted the .ulp as I copied it to another PC and get the same error. I did some digging and found an archived copy and it started without issue, so I got that under control. Something else I noticed while dealing with this; DataXport wants to open with the last .ulp it ran (which is expected), but if the last .ulp wont run (as in my case), then DataXport just falls flat on it's face. You would think (that like most programs) it would tell you that the file cant be opened, and prompt you to start a new file. Just my opinion... JohnR
  3. Hey All, I ran into a snag this morning, I have a pc whose only job is to run 3 instances of DataXport, and collect data from different processes around the plant and dump them into folders on out network. Something happened overnight, and my DataXports stopped responding, I got them to shut down, then rebooted the pc. One of them started up ok, but the other two wont start. One gives me this error; And the other this; Anyone a way to fix these? Regards JohnR
  4. Hey All, I have a possible upgrade project coming up, replacing some old automation direct plc/touchscreen controls. my first plan was to use a V570 (or V700) and do my I/O expansion rack style so I can have the HMI in the panel door and put my I/O a couple foot away without re-routing (much) existing wiring. But, now I'm thinking of going UniLogic/UniStream, a bit overkill for the project, but would be my introduction into this product line. I've played around with UniLogic a bit but haven't yet built a real project. I've been going through the hardware aspect on Unitronics Website and think I got it figured out but thought I'd throw this out to the forum community to double check my thinking. the existing project consists of; 20 digital inputs (sinking) 18 relay outputs 10 analog in 2 analog out So going through the Uni-I/O list I come up with the following modules to cover my needs: (2) UID-W1616R to cover my digital ins and relay outs (1) UIA-0800N for 8 of my analog ins (1) UIA-0402N for 2 more analog in and 2 analog out then it looks like I need; (1) UAG-XK125 Uni-Local expansion adapter (1) USC-P-B10 CPU-for-Panel (1) USP-070-B08 HMI Panel Does this look correct, or am I missing something? Regards, JohnR
  5. I always tell my guys that get confused, "to a computer, zero is a much a number as one is, only people think zero means nothing"
  6. +1 Aus, I've mentioned a couple times in the past that I have made up a drill template that I lay over the snap module and put some holes in it. seems it's been a few years back when the PCB on the snap was changed to allow clearance in the corners, and screw bosses were added to the PLC's, so it seems there was a plan for screwing the snap on, but just never implemented. I would like to see the snaps delivered with holes in place, and a set of screws for mounting. And as Aus said, the pins could be a bit longer also. JohnR
  7. Aus, you are correct, that is much simpler then my net full of math...... Flex, I'm not sure why MF's are excluded from a lot of stuff either, but at least you bumped my mind into looking at the Float functions available.... We are a little closer to an Elegant solution JohnR
  8. Flex, this is the direction I was leaning, something like a Vector-Shift-Left, plug a value into the starting address, which then bumps the rest of the values down, then do the math. I see the Store Direct under Math/Float/Basic functions, but (unless I'm missing the obvious), you can't do vector functions with MF's. So, are you thinking that I should have a net with 6 of these Float Store Directs in series, each moving the previous value to the next, then doing the math? Aus, I was thinking that if I plugged one value in and dropped one off, then did a sum & divide, that would be a rolling average.... JohnR
  9. Hey All, Anyone have an elegant way to do an average on floating (MF) numbers? I am reading a float value from a device every 10 seconds, but saving that value once a minute to a Data Table, I would like to keep a running average of the 6 reads per minute and store that instead of whatever the value is at that instant. Some sort of FIFO arrangement where the newest value comes in and the oldest value drops off with an output value of the running average. I've used the Filter FB before with integers, but that doesn't work with floats (unless I'm missing something). Any Ideas? Regards, JohnR
  10. Yep, been thinking about that lately, I've been making tounge-in-cheek comments about retiring for a couple of years, and the bosses say "yeah, yeah, sure you are, who'd take your place?".... I got a new manager last fall, and first thing I said to him was, "well you know, I turn 62 next year, and I'm thinking about retiring"..... 🏝️ Now I have a young protege that I'm supposed to teach "everything I know" (by osmosis I suppose because I still don't get a lot of one-on-one time with him), but he's a sharp young man and slowly picking up on things.

  11. +1 to that Aus, I cringe every time our IT guy moves something else to a cloud based app. we lost our internet connection last week (fiber cut somewhere), and the whole front office went idle cause no one could get to their work.... geez Aus, I haven't heard that term since they started making sliced bread🙃
  12. In my case the answer is YES...... We probably ALL have at one time or another But that's the reason we're so anal about saving to multiple locations, lesson learned.
  13. Same here Flex..... I save to a new file name daily, appending the file name with the days date, such as; 1210 formax 03 20 19.vlp If I do a lot of changes I will sometimes add an A, B, C after the date and have multiple saves in a day, plus I add the PLC model to the name also. So far as storage, I work off a USB hard drive, and try to be diligent about copying my files to my C drive and a network drive. And as in other recent discussions, I'll save my version number somewhere on a display; v032019
  14. Thanks Guys..... It was as simple as changing the site option from "create Excel file" to "create .csv file" and using the default comma separator..... In all my other DataXport sites I've used the Excel file option and it always worked as expected, but this is my first time dealing with floating numbers... Live and Learn 🤓 JohnR
  15. +1 to what Flex says..... This beta version seems to be a big problem lately, it's great that the beta is available for seasoned users to experiment with and help find bugs, but we are seeing too many new users grabbing the beta version for their first programming experience....
