  1. Ahh... if Joe T. can do it I so can I. Not saying it's because I'm smarter.... Just relentless and tenacious. Once I get my head around something, look out, it's like I'm running with scissors. lol plus there’s alway the “ask Joe” option if I get stuck.
  2. Thanks for sharing Joe!! Perhaps I am resisting the change to UDFB’s.... but if it works then it works. If you call it “easy” then I’m sold.

    UniLogic vs VisiLogic programming

    Rog: If you have any specific questions in the future everyone on the forum will help if/when they can. As has been reminded to us recently: this forum is mainly comprised of users and is NOT the official Unitronics support channel (although some support team staff are members and answer). If it is an urgent issue call/email support and post here. It usually evening/weekends when I cruise the forums. Some of the gurus frequent late at night. The not calling subroutine has got me more than once in Visilogic and UniLogic, I'm finally learning if bits/integers are unresponsive to check for calling first (before panic mode, lol). The seminar was worth my trip for the "control+enter" to CR a text line. That one had stumped me for some time, I was creating second and third text boxes for extra lines of text. Granted that was probably in the help somewhere. Another thing I've learned is to scour the help section for info. Visilogic help is excellent and UniLogic help is "filling out" as time progresses.

  4. I ran into a bug that was a show stopper a few years back. Here’s the good news: a fix was released. It took a few weeks, keep in mind (someone correct me if I’m wrong) software fixes come out of Isreal. If anyone gets a fix released in less than a week please let me know how it was done. Unitronics is pushing the envelope of what a PLC can (or was ever intended to) do. The competition won’t have the same bugs when they don’t even offer the same features. Would you mind sharing what the other bug is? I am planning on developing new applications for several Unistreams this year in a manufacturing facility. Everyone depends on swift support, these PLC’s control the machines that control our paychecks. Sometimes I’ll find a solution on my own before the forum or support team replies; other times I have to wait it out. I’m not a software hacker so bug fixes have to wait.
  5. Fair enough. I predicated it with “quick fix”. Unitronics is good about feature requests (generally) but they can take some time. I envisioned a PTC contact to defeat screen saver and an NTC contact to restore sceen saver at client disconnect. Theorically that leaves nothing to forget. Annoyinng: I agree. I’ve been stonewalled with similar issues myself. I work with another major PLC brand and they have their issues too. For the price, features, support, and possibility of feature requests making a release; I deal with the little things and enjoy the greater good I can realize with Unistream.

    help needed for programing

    What PLC model/series? When you say PC, controlling group of PLC’s, how? Are you talking HMI software like Wonderware on master PC? Without some HMI software for PC you could use remote access (or VNC if Unistream) to a single master PLC that in turn controlled others via MODBUS. Vision has .NET however that is out of my league. Both Vision and Unistream have webservers. I suspect the other guru’s will ask For specific example of what/how you are controlling on the group of PLC’s. There are ways and I’m sure the group here can get you pointed in the right direction. When you say “user interface” on PC it leads me to think HMI software that would in turn exchange data via OPC, MODBUS, or .NET. If you don’t need HMI at each PLC look into remote I/O to a single PLC then remote access that PLC on PC. Need more info to really hone out a good recommendation.
  7. Perhaps a unique bit that responds to VNC screen clicks. Could be ORed in ladder with general.touched bit. Hopefully next release will fix the “number of VNC connections” bug as well. If that counter worked reliably it could “partially” solve the screen saver problem. A compare could detect when a VNC Session was established and disable screen saver. When connected clients=0 screen saver could Resume. I believe there is a VNC connected bit, if you’re needing a quick fix you could defeat the screensaver when the VNC connected bit is true .

    UniLogic vs VisiLogic programming

    Not sure I understand the need to STORE "grade a" to itself. Unless it's to a different data type with same tag name (didn't think UniL allowed that). It's a different animal than Visilogic, no debate there. I am getting used to Unilogic. I get annoyed by UDFB's being put in place of functions that used to be integrated in Visilogic. To be fair (in my critism) Allen Bradley is doing the same thing in CompactLogix, functions integral to uLogix now require complex subroutine (ex: day of week and scale with parameters). Examples in UniLogic: vector linearization. the training is good. I did the UniLogic class with Dan Logee in Rockford a few years ago, highly recommended.
  9. Where do I find the "demo" project file that would be in a new Unistream when it's powered up fresh out of the box?
  10. The serial protocol block should facilitate you "home brewing" MODBUS structured write commands. @Joe Tauser would be the expert in that arena.

    Local variables not incrementing

    UniLogic is NOT = to AB. The sooner I accepted that the easier I could sleep at night. It's a semi-reciprocal relationship: AB can do things UT can NOT and UT can do (probably a greater quantity) of things that AB can NOT. Pick the tool that best fits your mission (or budget in some cases) and run with it. On another note: only one of my suggestions made it into a version UniLogic, only because I could prove it worked with Vision but not with Unistream. Involved MODBUS, a Unistream master, V430 slaves, rs232 radio modems, and no (user definable) serial data timeout.

    String to Num

    I had a crash course in UniLogic string to num conversions (formatting/handling). You have to remove leading spaces and trailing non numeric characters if I recall correctly. The Visilogic string to num FB is more flexible as to what it will convert. If your ASCII string is purely numeric characters you should be Okay. If you need a subroutine to strip off other characters let me know. I could share a snippet of code I used.
  13. hi ,may you help me? for this error

      Hello Meysam,

      This not an error, this is only a mode and currently it's on STOP mode which means that it's not running any application if there is any. Try download an application to it, that suppose to solve this issue.

  14. An ohmmeter with an RS232 port would be the most logical approach in my mind. VOM talks ASCII to V570 via serial port then comparisons/decisions could drive outputs/actions.

    Protocol scan telegram RS232 ASCII

    By filter the float values you mean extract for use elsewhere (separate from the rest of the telegram)? I have done something similar but on a smaller scale using find in substring and remove from string FB's. It would be a more complex construct for what you're doing, doable none the less. I agree with NahumS, need to see it in context, give an example of the extracted floats? A table, CSV, loaded into an array?
