Kojekude Posted January 27 Report Share Posted January 27 Hello, I upgraded firmare from 1,32.xxx to version 1.35.227. I cant download program to PLC. Program is just configuration (PLC model, IP address). I tried with different Panel resolutions - without result. PLC is USC-B5-TR22. Link to comment Share on other sites More sharing options...
Saragani Posted January 28 Report Share Posted January 28 Hi, Is the PLC near you? If yes, then export the project to a Disk On Key (USB Flash drive), put the Disk On Key in the PLC and load the project from the UniApps. This should sort the communication problem Link to comment Share on other sites More sharing options...

Kojekude Posted January 28 Author Report Share Posted January 28 The program in PLC is same - in version 1.32 Link to comment Share on other sites More sharing options...
Saragani Posted January 28 Report Share Posted January 28 Not a ulpr file, but: Plug is the Disk On Key to your computer, and then: In the new opened window: You need to select "Removable Drive", and it should auto detect the Destination Drive (for example: E: ) Check the "I have read and understand the guidelines" Plug the Disk On Key to your PLC Click on "Create File", and then click on the "Import Application" from the Flash Drive, and you should see that it is writing "Downloading" and after it's done. the PLC should communicate with the PC again. Just one note: Make sure that the project that is currently opened, is with the type of the PLC that you are going to import the project on, else the PLC will either tell you that it doesn't find a project to import, or it will import another file (matching the PLC), which might be of version 1.32 or older.

CIC Posted March 3 Report Share Posted March 3 Hi All, I have updated to V1.35.227 and have a USP-104-B10 hmi with an extender for the I/O, then 1 x UID0808T and 1 x UIA0402N module connected. I imported an existing program that I had running correctly on v1.31 software. I upgraded it to suit V1.35 which was fine. I updated the firmware on the new hmi to suit the v1.35 software which went all good. But I couldnt establish ethernet connection between pc and hmi. So I was told to export the application to a DOK usb stick, which I did. I downloaded the application to the hmi directly from the usb stick and the application has loaded, i/o cards are happy and it appears my application is running. But I still cant get online via ethernet with my pc. I was told that loading the application via usb stick would overcome the issue of not being able to connect, but it hasnt. I have set the IP addresses correctly in the hmi, to match the application as indicated on the pc. I have also gone into settings on my pc to make sure there are no firewall issues. But still cant get connection. I have tried different ethernet leads, I have loaded the unitronics software onto another pc, still no success. Anyone got any suggestions for me please.

MVP 2023 Joe Tauser Posted March 4 MVP 2023 Report Share Posted March 4 Make sure you're setting the panel IP address, not the CPU IP address. The PC communicates with the panel. You can check the addresses on the PLC itself using UniApps. Joe T. Link to comment Share on other sites More sharing options...
HansCZ Posted March 4 Report Share Posted March 4 Have the similar problem. Somebody adviced this But it did not help me. I think the solution is to wait for 1.36 as in the current version there are more bugs (time schedule for instance). Link to comment Share on other sites More sharing options...
