  1. Thanks NoamM I will upgrade to the latest version the next time I am on site. I can see the "clear alarms" bit in "ACTIONS" but this only clears all active alarms. Is there a bit I can set to clear the alarm history? Normally after commissioning and testing a system I have many alarms that I have tested. I dont want the customer to see these alarms or he will think the unit has had major problems. Forget the second part - i found the location of the clear button in the properties window. Regards Denis
  2. Hi Alex Thanks for your reply. The unit is on site and has been running for a year. This is the only issue I can see. I dont like upgrading the software on a unit that is working unless I have a good reason to do so. It is difficult to get downtime on the machine and they normally give me a very small window for modifications. Do you know if this is a known issue with 1.28.34 that has been solved with later versions? Also is there any way to completely wipe the alarm history? Regards Denis
  3. Hi All I have a unistream 10.4" PLC+HMI. I am using program version 1.28.34 I am using the built in alarm function and also using the alarm history. The problem is that when an alarm occurs it does not always get added to the top of the alarm history list. I have set the view to default by date. I am using the date format dd/mm/yy If i get a new alarm it sometimes appears on top of the list or sometimes if I scroll down it will be in the middle of the alarm history. Does anyone know if this is a known issue with this program version. I dont want to upgra
  4. Thanks NoamM When is the expected release date for Version 30
  5. Where did you get 1.29.145? the latest version appears to be 1.29.111
  6. Hi Bernd I think this behavior is correct. For example if you want to run from midnight for 1 minute you set the start for 00:00 and end at 00:01. It runs for 1 minute and stops at the start of 00:01. If it ran to the end of 00:01 it would have run for 2 minutes The problem is that the schedule does not allow you to enter seconds. If you want to run for 24 hours set the start to 00:00 and the end to 00:00 Denis
  7. Hi I think if you select project in the top left corner of VISILOGIC. Then select properties. Under the Colors tab, I think it might be "marking view color" that you change to the same background color. Regards Denis
  8. Hi Charisteas Right click on the curve you want to display and set the position of the decimal point in "decimal format".
  9. Hi Charisteas Right click on the trend you have problems with on the left of the screen Select properties. Make sure that the Run/Stop bit (in this case MB24) has a power up value of 1. The trend will only start recording when this bit is powered up. I have forgotten this on many occasions and it can be difficult to troubleshoot. Regards Denis
  10. Hi DaveH The configuration should have downloaded with the program you have. Also remember that when you download the program to a new PLC you will need to manually enter any setpoints or timer values unless they are assigned power up values. All registers will be set to 0 unless the have power up values. After download power down and restart the PLC.
  11. Thanks Ofir I didnt see that. That solves the problem. Regards Denis
  12. Thanks Kratmel and Aus. The post referenced above is similiar in so far as the buttons pressed on the HMI can be seen on VNC. The buttons pressed on VNC can also be seen locally on HMI The post offers no solutions, Aus - The password that is entered is masked with stars, but as the buttons are pressed on VNC or local on HMI, anyone can easily see the "button pressed" indication on the opposite device. To get someones password just tell them you have a problem and as they log in remotely watch which buttons are being pressed. Maybe it is just the VNC viewer I am us
  13. When connected remotely through VNC, if someone is standing at the HMI they can easily see passwords as they are being entered. The button presses appear as the keys are pressed remotely. Many times when I connect remotely is to troubleshoot and there is normally an operator looking on locally. Is there any setting available to disable the key presses when connected remotely? Regards Denis
  14. Hi Vinicius If you want the timers to continue to run when you leave the display, you must put them in a subroutine that is being called all of the time. On rung 10 you are using a positive transition contact of MB 35 to start timer 2. This may explain why you are stopping at 4 seconds Regards Denis
  15. Hi Kevin Have you the latest software on the PLC? On your screensaver if you have an image, assign a touched bit in order to go to a specific page, this should work with the latest version and most VNC Another way is to put a button the full size of the screen with a touch property to take you out of the screensaver. In the button settings set the background to transparent so that it cant be seen. These two methods mean that you don't need to use the screen touched bit Another alternative is if you click on the system tag at the bottom of UNILOGIC, you will see a bit a
