  1. Sometimes I have issues with not accessing data tables correctly or "hanging" it's usually resolved by doing a fresh download. Not really sure why. But it usually happens after I have been messing around in the program or DT folder.
  2. Pretty sure the 7" will as well. The HMI houses 2 rj45, 2 usb host, 1 usb device, audio jack, micro sd card. The CPU has RS485 and CANBUS.
  3. Any recommendations on a good electrical schematic software? Schematics are my weak point and I'm doing more and more machine builds requiring complex schematics so it is time to learn a full featured schematic software. Thanks in advance for any recommendations. -Swervomotor
  4. I realize this is not an answer to your issue but have you considered writing the Unilogic program to handle all the scenarios and use data tables for storing/accessing process specific data? I have done this where you separate all the different sub-routines then CALL them in order of the "process step" table for whatever part it's running. Then all you would need to do is send it the part name and do all your data/process loading inside the PLC. -Swervomotor
  5. I've had 2 SD cards go bad this year. I think if you really need that 20 years of data you would find a redundant way to back it up. A cheap NAS can easily be configured as FTP server and mounted remotely or locally. The 32 limit is the default in Unilogic, you need to change that or it will start auto-deleting older files. I'm not sure but I believe it also has difficulties with subfolders.
  6. I would check the aspect ration of whatever "screen" (tablet with VNC viewer) and match that as close as possible to the screen. For instance I would go with the low cost Unistream 7" with a 16:9 aspect ratio and find a 10"ish tablet with that ratio. Scaling is done through the VNC viewer on the tablet. I use RealVNC as a VNC viewer and the scaling can be adjusted in the properties of the connection. On the Unitronics website I see: 7" 16:9 10.4" 4:3 15.6" 16:9 -Swervomotor
  7. You should be able to create a new file no problem, Do you need a new folder for each file? Or can you create a folder on the SD from a PC and store your files in that folder? Your method of backup you will need to change the SD file # limit from 32, but you might start getting issues with so many files on the SD card as time passes. We store them to the SD in a folder then use the FTP functions to send them to our local FTP server, then overwrite. SD cards go bad.
  8. To be honest this could be easily accomplished with a micro controller (like arduino, ESP8266 or ESP32, or even a raspberryPi), power supply, and a opto-isolated relay board. >$100 Unless you are trying to teach ladder logic or the unilogic environment it is quite overkill. IMO -Swervomotor
  9. I have not but am strongly considering a unistream 10.4 multi-touch for this purpose, or possibly a lower end model and VNC from a tablet. It has so many built in Coms I think they would be great. I would need these questions answered (through research) before I decided to pull the trigger. Possible to interface with Mqtt? For voice control through voice assistant, cell phone app, and PLC control of existing networked smart "things". Power/cost study to determine if I can make the distances I would need to my entire property with centralized I/O or do I need networked distribut
  10. When I have issues with the SD card I just replace the SD card, not saying that's your issue but a lot of SD cards now are crap out of the box or shortly after.
  11. I've had better luck (actually getting something done with IT) having IT setup an FTP Server on the network and giving me a client username and password. I then setup the client on the unistream and FTP send to send the CSV on my end. This way works better for me because then I can add a bunch of machines and don't have to have IT involved because I re-use the username and password.
  12. I just tried to install a later version on windows 10, checked the box to keep the old version and got this error box. If I pick "ok" it will un-install the previous version, If I hit "cancel" it exits out of the installer.
  13. I would look at: SD card present? SD card formatted correctly (fat32) Max number of files on SD card not exceeded (this is a set-able number in unilogic) Make sure you are not resetting the contact that starts the save in the same rung (I remember this was an issue for me for some reason) I would then email Support: support@unitronics.com
  14. I'm not sure if this is the answer but I remember the file name had to be of specific format, "yourfilename" leave off the csv.
  15. I routinely find myself bouncing between 3-4 different revisions of unilogic depending on what version the program on the controller was created on. I've only been able to do this by uninstall whatever version I have and re-install the version I need. Is there a quicker way to somehow keep multiple versions on the same box without having to go through the uninstall- install process?
  16. I usually do a webpage for simple projects but thinking now VNC may be the better/fastest option in this situation. Thanks for the input on this issue
  17. Schleuniger is notoriously difficult to work with on "custom" stuff. We program all ours with Iquana, but I don't think you can access /edit the "program" registers remotely. PS. have you had any issues with your HMI's on those machines? We've had several fail.
  18. What is the best/reliable/fastest way to "cast and control" the HMI screen to a tablet (on the other side of a machine) Hardware would be a Unistream, would a VNC veiwer or webserver be the best option or are their other alternatives?
  19. After FTP is received I usually: 1st "Convert CSV to UDTF" 2nd "Load DTI From File" I would use a HMI element "Combo Box" to show the operator the available files. Each file name in the combo box would be linked to an index number which when the " Selected" bit of the combo box goes high stores the appropriate file name as a string to parameter "C" of the "load DTI from File" then loads that data from Parameter C-->A The downside to this method is that the available files listed in the combo box would be fixed so you could not change them easily. The way I hand
  20. I would like to be able to open 2 projects at once on the same machine. It would also be nice to copy/paste ladder between the two.. But I would be good with just being able to compare side by side.
  21. Is there any built in function to compare 2 projects side by side and show the differences without going through line by line?
  22. You can use the built in functions to send a CSV file: HMI button sets a bit--> "Store DTI to File" Make sure to set "F" to 1 so it saves a CSV file onto the SD card--> Then when the "H" status finishes (1-->0) you can use the built in "FTP Send" to send that CSV file you named in the "Store DTI to File" Then go find it and open in Excel (import as CSV). Now if you want to import it back into the PLC after you make changes to the file you need to reverse this process: save as CSV (on computer) "FTP Receive" "Convert CSV to UDTF" "
  23. Look a the help file under "timer TP" and "increment" You can use the falling edge of Timer.Out of one timer to start the other and increment your counter. I try to avoid using direct coils if possible and use SET and RESET coils.
  24. Ok, looks like the Node RPI is restricted as read only from ladder so Q1 is out. I am however wondering about Q2 above, The enable bit is read/write from ladder so wondering about any "start up" delay.
  25. Good day everyone, I have a project with 20 Ethernet/IP scanners running on a unistream 15.6". The machine network is separate from the plant network and goes through a layer 3 switch with VLAN port. I also have 6 Modbus TCP devices running on the machine network. I noticed when debugging the program I was having some bugs from what I assumed was network clogging with cyclic communication. By lengthening the RPI on some nodes I was able to resolve most issues. I also have a lot of disconnecting issues when trying to monitor in Online mode. I notice in the Help file under the Scanner
