  1. If you have done a lot of downloads to the PLC data can get stored in registers where you might not have intended. Every now and again it is a good idea to download a blank program and do an initialize and reset. then try your program again.
  2. Hi Aleix When you disconnect the wire from terminal 9 of the PLC and put a meter in series with the input, what reading do you get. make sure that the polarity of the meter is correct with the negative probe in terminal 9. Do you get the same 8ma or -8ma or nothing. If nothing re-check your wiring. If -8ma reverse the wires on 6 and 7 of the INOR. If it is 8ma re-check the jumper settings and the hardware configuration in the program.
  3. Hi Aleix Are you using the same 24v supply for the INOR and the PLC? If not make sure that both 0v are common for the supplies.
  4. Hi Rainer1 The Alarm displays are already built by Visilogic. You don't need to create a display, just call the display in the display in the ladder. Its difficult to see what you get if you don't have a PLC running.
  5. Hi Tim You can use any document program like WORD to type the symbol you want. Then copy the symbol and paste it into the TEXT AFTER field. Regards Denis
  6. Under the Vector tab you can use the bit to numeric or numeric to bit. For the source of the function you can select inputs or outputs.
  7. 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.
  8. 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.
  9. 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.
  10. 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
  11. 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.
  12. 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
  13. 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
  14. 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 just me?
  15. 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 messages.
