To a .txt not that I know of, to a .csv which can be opened in a text editor, yes. The way I've handled this in the past is to:
FTP receive (go grab the original .csv file)
Convert CSV to UDTF
Load DTI from file
Make whatever changes in the data with PLC DTI functions
Store DTI to file with .csv (Convert back to .csv)
FTP send (send it back to the network folder)
Also you can setup a Webserver on the PLC to edit table values and follow the same flow as above after making changes to update the (original) file on the network.
I usually have the PLC go grab the network file at Power on, and also have a button on the HMI and webserver to go grab the network file that way we can make changes to the data and re-fresh it on the PLC remotely.

I have not looked at your file but I know your host email account needs to be configured for SMTP. I would start there if it hasn't already been configured.

Joe,
Thank you for the direction! Swervomotor pretty much nailed my problem, the input sizes differ between the Omron vision system and the Unitronics.
Nice catch Swervo!! Impressive!
Shane,
Happy to help, glad you got it worked out.

Check the Panel IP address and program version number in UNI APPS by press and hold the top right corner of the HMI, Make sure your IPV4 IP address under network settings on your laptop for the USB network adapter is on the same subnet eg( if HMI is 192.168.1.20, then you should be something like 192.168.1.30 with the same subnet mask eg 255.255.255.0) Make sure you are using the same version of Unilogic that the project was downloaded with by confirming in UNI APPS the software version. Lastly make sure you are on the same physical network, if you go through switches to get to the machine are they actually connected?

FTP is the way I do it, I use filezilla but I'm sure you can use any of them. Just set up the FTP server on the PLC and use the credentials to go grab what you need. (Solutions explorer ->PLC communication -> protocols -> FTP-> FTP servers) If you have a local server/NAS you can use the FTP function blocks pretty easy as well to do automatic send/receives.

I am a control engineer and was brought in on an existing project consisting of a Omron vision system and a Unitronics USP-070-B10. I was tasked with adding additional measurement tools to the vision system. The vision system is utilizing an 10 indices array(float) nested inside a STRUCT. I am planning to add 50 more measurements to the vision system. I thought it would be easier to just increase the size of the existing array to accommodate the new measurements. After increasing the size of the existing array I compiled the project and oddly enough I had about 40 mismatches between the PC and the PLC including communication mismatches that were not there prior to the increase. I went ahead an downloaded the file to the plc. After the download was complete I could no longer connect to the vision system, nor could I connect to the collaborative robot that the Omron camera was mounted on. I generally only work with Beckhoff, Allen Bradley, or Siemens PLCs, so I am not very familiar with Unitronics. I know in the past 30 years of programming I have modified the index size of arrays on countless systems, and never had an issue. Has anyone ran across a similar issue when increasing the number of indices in an existing array?? I modified nothing else in the programming except for the number of indices in one array and literally nothing works. Does this have something to do with the way the PLC is allocating the memory? I have never seen a option in any other PLC to "Reallocate Memory". The documentation doesn' t mention "Reallocate memory" anywhere, so I have no idea when or why I would need to use that. Can anyone shed some light on that??
Thanks,
Shane
I agree Support is going to be your best bet but I would start by looking at:
How are they communicating? Ethernet/IP, Modbus?
When adding vision "measurements" in the vision controller, does the communications struct that was previously running already have place holders for those bytes? Hard to put into words but if you made changes to the communication struct in the plc it would not match the output coming from the vision controller. In the picture attached if the input size changed (by adding components) unless your actual output coming from the Omron also changed size you would have a mismatch and it likely would not work.

Your PC could be missing the driver for the usb to ethernet adaptor , or did you check the IP and subnet on your laptop (assuming) so that it was on the same network as the PLC (eg 192.168.x.xxx).

We had this issue on a 15.6", non-responsive intermittent response. When you touched the screen at different places the x,y touch coordinates would not change. The recommendation was to loosen the screws and remove any screen cover but that did not fix. Ended up returning it under RMA and it was defective.

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.

So, the 10 and 15 inch USL series HMIs can connect to VNC through ethernet without the cpu? I'm looking for a solution like this, but didn't realize the HMI came with rj-45 ports.
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.

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.

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.

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.

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

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.

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

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 distributed I/O w/local Power supply.
To be honest I wish they made a POE arduino nano/micro/esp for this purpose.
I hate changing batteries so while something like a battery powered ESP32 would be great (2 cores, wifi, etc.) I need something that is POE or hardwired to central/distributed I/O
I'm sure you could do PC control for cheaper but I'm so familiar with the Unistream the cost difference is much less important then the learning curve and hardware/software troubleshooting.

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.

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.

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.
-
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:
-
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.
-
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?

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
Index Data Table Issue
in UniLogic Software
Posted
Not really enough to tell what the problem is but it looks to me like you are using local tags in the function vs Global tags. I wasn't aware of a limit but it makes sense there may be a limit to the number of local tags you can define per function. I would check your Data Table name is in the global tags area. Outside of that I would contact support.
