PLIN-API & PlinMng.exe Version History

2021-12-14 - Version 2.8.1

Bug fixes:

  • The GetErrorText function may not always have returned a text
  • The hwpBossClient parameter returned an unexpected value when it was set or retrieved
  • If the maximum of LIN hardware channels (255) are connected to the service, another new hardware channel could throw an exception


2020-12-03 - Version 2.8.0


  • Added new client parameters clpLogStatus and clpLogConfiguration for the functions LIN_SetClientParam and LIN_SetGetParam, to set up the new logging functionality
  • Like the PCAN-Basic API, the new logging function can also be activated via the Windows Registry
  • Added new hardware parameters hwpScheduleActive, hwpScheduleState and hwpScheduleSuspendedSlot for the function LIN_GetHardwareParam
  • The error codes relating to the schedule table functions have been revised

Bug fixes:

  • The LIN_RegisterClient function did not recognize the maximum number of clients and always returned a handle 1 if 255 clients were already created. In this case the function now returns errOutOfResource
