  1. Some time ago (I don´t remember Visilogic version) I had a similar issue. If I remember well, my solution was to restore all system images (project | system images menu) then download again the project
  2. In addition to Kratmel comments, make sure the snap is properly seated on the back.
  3. Leave empty "initial value" field
  4. I don´t understand what you need. As I see, it is modbus protocol, and checksum (CRC) is automatically added by PLC, calculated right the way stated by the standard
  5. It´s not working as expected because the routine 10-Leak Test Validate is not being called anywhere.
  6. Recently I had problems with snap-in module analog inputs stop working (scaled value fixed at 0). I discovered it was caused by module high temperature, even the cabinet was properly cooled, so until a new module arrived, installed forced air directly to the module and the problem was gone. Check cabinet and module temperature
  7. Unistream has user acces control - UAC - where you can assing roles, users and passwords to limit actions, disable buttons and so on based on the user logged in. Take a look to this feature.
  8. In addition of Flex said, verify that your outputs are not used in other places, if so, based on the logic, they would turned off despite you are turning on here.
  9. Probably you would need Unistream Data Converter Suite (https://www.unitronicsplc.com/Download/SoftwareUtilities/UniStream_Data_Converters_Suite_1_0_18.zip) to get access and convert datatable to Excel to be able to modify it.
  10. There´s a function called Linearize, take a look at it (ladder toolbox under math section). That´s what you need.
  11. This is the way I use function: I don´t know if your issue is name related as I only use single word to filenames. One suggestions: to load the whole table, start from 0 and use "Number of Rows" tag from data table target .
  12. If you post your code, I can take a look. So far, make sure SB168 is set at power-up
  13. I noticed that using a different version of Unilogic to get online (other than the version used to program and download to PLC) gives not match error. I suggest you to use same versions on both computers.
  14. I learned something new today, thanks Fernando, I didn´t know about such string library capacity to store indirect strings.
  15. In addition to Joe´s comment, both set of instructions are placed on the same rung, so positive transition of MB71 wont be detected.
  16. You can open V1040 - Alarm Example.vlp. It is located under Help | Examples | Version 900 | Project Examples | Ladder
  17. I´m not pretty sure of this, but try changing language using "Project|PLC display language" menu
  18. Some other FB also have it: Modbus config, PID config, Events. I´ve found it useful when tunning PIDs
  19. I use custom controls to achive what you suggest, then place them in all pages
  20. It´s just a warning. Adjust the object to the required size to show the maximum value you expect to get.
  21. "number of elements" must be equal to 1 for all columns to be able to exchange data with Excel
  22. Each MI contains 2 ASCII characters, then you need 8 MIs for 15 characters including null mentioned by Flex Make sure to reset (or fill with space ASCII code) all remaining MIs when using less than 15 characters, otherwise PLC won´t show what you need.
