Bug Fixes

  1. Fixed an error when entering a variable name containing only square brackets.
  2. Fixed a bug when undoing a change to the type of a variable bound to a visualization.
  3. Fixed an error when reading the "Analog filter" parameter.
  4. The range of acceptable values ​​for the "Analog filter" parameter has been changed to 0 - 0.255 seconds. Note: If in a project with an analog input in the "Digital" mode, an invalid value for the new range (0 - 0.255) is set in the "Debounce filter" parameter, then when you try to change it to another invalid value, the value will reset to 0 seconds.
  5. Fixed an incorrect error message that occurred when the EEPROM was full.
  6. Fixed an error that occurred when clicking on a column name in a variable table.
  7. Fixed an error that occurred when hovering over the variables panel.
  8. Fixed an error that occurred due to an incorrect value of the "DHCP Mode" parameter when changing the target platform from PR103 to PR103[M02].
  9. Fixed focus shift when binding a variable to control properties.
  10. It is prohibited to create ST functions from ST function blocks and vice versa.
  11. Fixed incorrect recording of the "Brightness" parameter value into the "Default Brightness" parameter in PR225.
  12. Fixed incorrect screen size when changing the target platform from PR225 to PR205.
  13. Fixed a bug when changing the target platform from PR205 with three AO to PR225 with two AO.
  14. Fixed incorrect number of buttons when creating a new screen after changing the target device between PR205 and PR225.
  15. Fixed a bug that prevented the array properties window from closing in the variable table.
  16. Fixed a bug where after changing the akYtec ALP mod, it would be impossible to open a saved project due to a missing container.
  17. Fixed a bug when changing the target platform to PR103 in projects using PID_REG.
  18. Fixed a bug where new array elements were added to the end of the list after resizing.
  19. Fixed incorrect array simulation after duplicating it in the variable table.
  20. Fixed a bug that prevented copying elements from PR110, PR114, and PR-Kit projects of previous versions of akYtec ALP to the current version of akYtec ALP.
  21. Fixed errors that occurred when copying elements containing invalid characters from projects of previous versions.
  22. Fixed a bug where memory usage information was not updated when changing the target platform.
  23. Fixed a bug where akYtec ALP would close when opening the extensions menu.

3.0.382

New

  1. A new data type, Arrays, has been added for the FBD language.
  2. Added the ability to configure the thickness and color of the focus frame.
  3. For the "Menu" element, a new toggleable property "In Focus by Default" has been added, which automatically sets focus on this element when the screen is opened.
  4. Added a "Loading screen" feature, allowing you to change the image displayed on second-generation devices when they are powered on.
  5. In the variable table, the "Show nested variables" setting now affects the variable count in the catalog.
  6. ALP now saves and transfers the structure of network variable catalogs, which is used by ToolPro when building the parameter tree.

Updates

  1. The devices PR110, PR114, and PR-KIT have been removed from the list of supported devices.
  2. Firmware for PR103 v1.12.0 devices:
    • Added support for arrays in FBD.
    • Fixed operation over RS-485 in 7n2 mode.
  3. Firmware for PR205 and PR225 v1.11.0 devices:
    • Added support for arrays in FBD.
    • Fixed operation over RS-485 in 7n2 mode.
    • Added support for custom startup images.
    • Added support for controlling focus frame color and thickness.
    • Added support for the "In Focus by Default" property for the "Menu" control.
    • Fixed a bug causing device reboots due to incorrect memory calculation for visualization controls with rounded corners.
  4. Firmware for PR200, PR102, PR100 [M02], SMI200 v2.77, and PR100 v3.12 devices:
    • Added support for arrays in FBD.

  2. Fixed an error that occurred when calling the CD32 and DC32 functions if their argument was outside the valid Int32 range.
  3. Fixed an error where changing the text of the "Text" element for second-generation devices was not recognized by the program as a project change.
  4. Fixed an error where the analog input parameters tab was not updated after reading values.
  5. Fixed incorrect display of input pins on the diagram for functions written in ST.

  7. Fixed an error where name checking in ST was case-sensitive.
  8. Fixed an error that occurred when switching to the slave variables tab in the variable table for second-generation devices.
  9. Fixed incorrect rounding of float variables in simulation mode.
  10. Fixed an error where exporting second-generation devices to an OPC server resulted in an incorrect byte and register order being transmitted.
