  1. In the examples that come with the program installation there is an application called "Alarms with time stamp" This is in the database folder "Normally" at this location C:\Program Files (x86)\Unitronics\Unitronics U90 Ladder\Examples\Data base It might help to achieve what you need.
  2. Yes. Thats what I have done before. The only problem is that if the problem is not sorted after the reset the power will continue to cycle on and off.
  3. There is no description in visilogic, but I have used SB90 many times to indicate a loss of communication. I know it works with a snap in block (goes high if the block is removed) I think it will also work with external expansion.
  4. Hi Nicklamp Please see below link, it gives the ranges for standard and enhanced controllers. At the bottom of that there are further links to webinars that will help setting up. if you have succeeded in reading MI's then you have the hardest part done. To read MI's you probably used the modbus block 3 - "read holding registers", for inputs use block 2- Read Inputs. Input 0 will be 6000h https://support.unitronics.com/index.php?/selfhelp/view-article/vision-and-modbus-communication
  5. That is a video I would definitely watch. The chiefs at Unitronics should jump at this offer. would make a great training presentation for all levels of user.
  6. When you are setting up a display, select numeric elements on the right hand side. Here you can assign an IP address or IP settings box that the user can use to modify addresses
  7. Thanks Aus/Joe Hi Aus - yes I did the repair via the system restore. I had a recent backup done and tried this first but it failed. Joe - I have followed the steps you suggest. File downloaded with no problems. Thanks for the help
  8. Hi Not really related to this topic, but related to downloading the file. I use Firefox browser. When I tried to download the file above and selected to save it to disk, the file appears to download but after a few seconds windows crashes. This happened twice before on another laptop, however this is a new laptop and it happens again. Windows explorer keeps trying to restart every second so I cant troubleshoot anything. The only way to get back working is to restore from a backup or do a system restore. Any ideas if this is a Windows, Firefox, Unirtonics or j
  9. I think this should be a message on the header of all posts. For example I get a default message when I post stating the following "Your content will need to be approved by a moderator". Many new posters get frustrated when their post is not posted, read or solved immediately, not realizing that this is a voluntary forum. When people try to post there should be a message advising them of this and also if they would like to also send to the official UNITRONICS support. It would be easy for the forum designers to include this than everyone needing to set up their individual m
  10. Hi I think the unit is listed in the remote I/O user manual. Try this link https://www.unitronicsplc.com/wp-content/uploads/2020/06/UniStream-Remote-I-O-User-Manual.pdf
  11. Hi KVJ When you have a situation like this where you do not know if the program is the same and if you do a download there is no way to go back you should consider the following. A V570 PLC is not a very expensive unit. If you convince your customer to invest in a spare unit, you can try the new program in that unit and see if it behaves as expected. If it does not work, just put the old PLC back. Regards Denis
  12. Hi Put the DOK into your PC Connect to PLC with ethernet cable In UNISTREAM click on "UNISTREAM MANAGEMENT" and then "REMOTE UPDATE" Half way down the window that pops up select DOK as the "target drive" Click on "UPDATE" at the bottom of the window and the PLC should be updated with the latest version.
  13. Hi On your initial post you mention that you can ping the PLC. Even though you cant go online because of a firmware mismatch, you should still be able to use the remote update function. You dont need the SD Suite just a blank SD card. Its possible that a USB stick in the PLC will also accept the files. Regards Denis
  14. Hi If you can communicate with the PLC over ethernet then you should be able to update using the remote update option. You will need an SD card in the PLC in order to accept the download files.
  15. 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
