  1. Not once have I said that. My responses are based on I don't know how much you know, as you are new here. Don't forget I am not paid, I am a volunteer who has put in countless hours on this forum often explaining the same thing again and again to people who can't be bothered to look up help files or delve into the forum. Think how you might react if you were again asked how to turn on a light switch! I have never had this issue myself, but I also only do linearisations on MIs. What happens if you convert your input numbers to MIs? Your needed output will still give the same accuracy on the smaller input range that is available with MIs. Using a counter based on SB13 will let you test this easily with your wanted time of 5 hours. I can't as I don't use 700s. cheers, Aus

  2. Pls upload the program you've done for the example above so that others can run it and check. I can't as I don't use 700s. Reading the above makes me think that you don't know a crucial thing that linearisation needs to work properly. It does NOT stop at the Max and Min values you specify. If your program is going to possibly give readings that will overshoot you have to have Max and Min compares going on that store the max or min value if an overshoot has happened. This is done directly after the linearisation in the ladder. This is a confusing thing for first time linearisation users. Pls read this entire topic: As far as I know this hasn't been done yet. One for @Cara Bereck Levy to ask? .....Again. I've always said I don't think it could be too hard, but I do know that the Vision system has limited "space" for mods. cheers, Aus

  3. Please read PID section in HELP. In your program no PID RUN fb present. Some add net needed in ladder.

  4. Don't feel bad, I once asked how to show elapsed time instead of remaining time on a timer in VisiLogic. It's always the little things that get you.

  5. I'm with Kratmel. I don't use Unistream but I am well aware of issues that can occur between seemingly identical plcs. Deeper looking then discovers fundamental differences in their specs. A simple test would be to load from the SD onto your plc, but this might perhaps work anyway because it is going from a simple to a pro. The other way is likely the issue. Ultimately, if this is the issue, you perhaps have no alternative other than having a simpler controller to do your work on. cheers, Aus

  6. Due to the fact that you have replaced the full version B10 of the controller with a simplified basic version B5, the functionality you have programmed probably does not meet the capabilities of a simpler PLC controller. That is, if you wrote a program from scratch for a simpler controller - probably the Unilogic environment would tell you that some of used functions are not supported. By making a simple replacement, you have avoided the messages of the Unilogic environment, but probably both used controllers are not equal in capabilities. Some option in Unistream built-in manual is marked with "For UniStream 7″ Pro only".

  7. 1. Test with SD card you already used. Does it works? 2. If you make full format for new (problematic) SD card - does format finish with no errors? 3. Find at Internet software to test SD card capacity and run test. What does test show?

  8. Joe, do you mean like this? cheers, Aus
