  1. Hello friends.I am using a PLC communicating with an UAC CB 01RS4. What I want to achieve is an meter MODBUS measuring the volt and amp value of a load, connected to a PLC via Modbus, this PLC is connected to a computer via ethernet.I managed to establish communication but didn't suceed. Indeed, All attempted sessions are fails and the status is 3 - Connection exists, but there is an error in the MODBUS commands. I have added the MODBUS module to the PLC on UniLogic, and all informations (Modbus panel, baud rate, data bit....) are correct. Then I've added a Master -> 'registers periodic' -> the modbus communication is the UAC-CB-RS4 and the adress is 5000 (which is the adress register of the Voltage measurement content (for the automate). I also tried to add a slave but still I have the same errors. If you have any clue on why I have a connection but the MODBUS command has errors, please tell me 😀. Thank you very much !!
  2. I didn't lose hope by resources about UAC, the user do not have time for expire password, I would like that it would be possible to modify password in first login. I have tried to create one logic for user control, but without sucess. Another problem, is to show current user , after logoff. The information do not update, when there is no user in use.
  3. Hello, How it's possible to create password time expired notification & save password in data tables in Unilogic program.. Thank You.
  4. Hi, first of all please let me know the difference between V1.29.111 and 103. (Version Changes and Bug reports haven't updated yet)! --- I am waiting for a solution in UAC idle timeout. It ignores if I navigate PLC through VNC connection and log me out despite clicks on the HMI severel times. Is it possible to reset Idle Timeout timer in every HMI changes? --- I noticed that I can't change the Message Box icons. After download it turns back to default green info symbol. Any solution for this in the new update? Best regards, Balazs Tarro
  5. Hey everyone, I have a little issue how UniStream managing passwords. If somebody is typing his/her own password on the PLC I can see all the letters via VNC connection. I mean I can see what buttons were pressed. Also the same in opposite situation. Our projects are monitorized by several user at the same time and it is not comfortable when a user sees admin passwords. Half-Solution: Using PC's keyboard --> only works with PC. People rather use mouse clicking Any solution for this? Best regards, Balázs
  6. Hi, In my project I have to do ladder logic to logout users. At this moment if a user is logged in UAC is ignoring the user's HMI changes, value changes or other operations and it logout in idle timeout. I'd like to reset the timeout timer if some operation in progress. UAC also can logout automatically during an operation or loading other HMIs. Do you have any advice to solve this? I've tried to set and reset Event update bit in every HMI changes (via HMI is active bit) with no results. Unfortunately Logout action is only able in HMI editor. Thanks!
  7. Hi, I have an issue in the UAC module. When trying to "Login" with an null/empty user field or valid user name and wrong password , the system put the last user logged in the UAC struct. I don't understand why, but the system go back with last user & group. Regards.
  8. Hi, In UAC (User Access Control) struct the next Group events are missing: - Change Group Name - Delete Group
  9. Dear all, I just update the PLC at version 1.22.13; also I update a project that I wrote with the version 1.19.xx; in this project I have enabled the UAC and insert some users with different levels..also I included a "service" user that has full access...when I try to upload the project I have an error "the password for UniApps Administrator could not be changed" and the download don't works. I tried to set the "service" user as "super group" but was the same. what I'm doing wrong?
  10. Hi, I have a project (HMI USP-070-B10) with several users and groups. Using 3 access levels into the screen controls. I have a client who would like to have full access without login every time when power on the HMI. Is it possible to make something like auto login or to make default user with full access? Thank you in advance, Ognyan Obretenov
