  1. Hi @Ausman! Yes, I have and no luck, but you are correct on the firmware. I just go with the newest visi version (Old habits), and it wants to upgrade to newer firmware to let me download the program into the vision. I found a vision350 PLC with older firmware and another computer with older Visilogic version. I tried my program and it works! I then upgraded the firmware on the vision and now it behaves same as I mention above. Now the question is, can I roll back on OS? And can I report this bug somewhere to Unitronics? This version was in the PLC and this is
  2. Hi all. For a few years, I have been using the HSC frequency measurement on the V350. My program uses the example that was given by Unitronics and I have not altered it much. Suddenly, my programs have stopped working when I download them to a new PLC. The HSC behaves unusual and gives me false readings. My program is to control micro water turbines and it uses HSC to measure the frequency of the generator. I am using a simple frequency converter that gives me pulses into my HSCO port. The pulses are 50Hz and I confirm using a digital meter that the input receives 50Hz.
  3. @Saragani FIXED! Thank you very much for this, I tested the file and it works perfectly. See the snapshot, one is with the file, the other is not. What was the bug? running out of memory somewhere? Again, thank you all for your help and Saragani for fixing the problem. Cheers!
  4. @Saragani Hi sorry for the delay, its finals at my university and I was bit busy. I just sent support email with my program. Thank you very much for this. Cheers.
  5. I can give you the program if you want, or remote access. If that helps. I know that if I press the "M" button I can see the rest of the graph. I know that the problem is on multiply computers, even with fresh install of remote operator, the lines disappear exactly same between computers. Using remote on Visilogic does not show this problem. See pictures:
  6. Hi I finally went to the place and checked on the PLC and the remote operator software. It seems to be some kind of bug on the Remote Operator.
  7. Hi Flex, Yes this is exactly what happens. I can see the data when I press the "M" button. I am not sure if this is doing something with the memory of the trend, but I am not saving data to the SD card. Hi Michal! I am using Remote Operator but I have not checked if this is also in the PLC display too, will do that next time. But thank you for linking your post. I am going to test the Remote Access program and see if it changes anything. Cheers. Arnor
  8. Hi, I have a V700 that has few trends on display. Randomly the trends goes black and the line disappears, and you cant see anything. If I press the "M" button the trend line that disappear is back. Its is very annoying because we need to see the trend and we have to log on to the V700 and press the "M" button to see it. Any idea why this happens? See attachment.
  9. Thank you very much. I separated all the blocks like you said and it started working! Cheers!
  10. Hi! My name is Arnor and I am from Iceland I am trying to establish connection between two Vision PLC's. I have the master: V700 and V350 as slave. I can use SCADA pc software to connect to the slave and read the data. But I am not able to read data from slave to V700. I added both programs to google drive folder (sorry, the programs was to large, and its a bit mesh): https://drive.google.com/open?id=1yL1h1ZvJomBeoY7v22UvHVeY09T4ooAC I am using also Serial modbus on both sides that works well. The PLC are set up like this: V700: V350:
