23.0.0 Release

Added

• Support for custom Switchboard with 16 Two-Switch ports
• The SDK can now log events for debugging
• Function fgt_set_log_verbosity to enable and disable event logs
• Function fgt_set_log_output_mode to set how event logs are returned to the user
• Function fgt_get_next_log to retrieve event logs manually as strings

Changed

• Switchboard ports A to D are now mapped to port numbers 16 to 19, instead of 8 to 11.

Fixed

• Fixed spurious errors being returned by fgt_get_sensorStatus.
• F-OEM no longer returns brief connection errors when using Flow Unit M+ or L+.
• LineUP and F-OEM modules no longer report that they are in sleep mode when a sensor or valve is connected or disconnected.
• Sensor regulation no longer stops on its own when started with the Flow EZ in local control mode.
• fgt_set_valvePosition now correctly rejects negative valve positions.
• Fixed lag when using multiple simulated MFCS instruments.
• Fixed flow rate sign when using Flow Unit M with calibrations HFE, FC40 and OIL.
• Fixed Flow Unit range (as returned by fgt_get_sensorRange) failing to update when calibration is changed.
• MFCS channel range is now properly capped at 7000 mbar

Resolves #68, resolves #65, resolves #60

22.2.0 Release

Added

• Support for the NIFS flow rate sensor.
• New functions fgt_get_differentialPressureRange and fgt_get_differentialPressure. For NIFS only.
• New functions fgt_get_absolutePressureRange and fgt_get_absolutePressure. For NIFS only.
• New functions fgt_get_sensorBypassValve and fgt_set_sensorBypassValve. For NIFS only.

Changed

• fgt_set_manual can now control the input proportional valve on the Flow EZ and the F-OEM pressure module.

22.1.0 Release

Added

• M+ and L+ Flow Units support HFE, FC40 and Oil calibrations when connected
  to Flow EZ or F-OEM

Changed

• [C#] Native library path is now resolved only once, to improve performance

Fixed

• MFCS devices without serial number in usb descriptor are now initialized properly
• Recently added functions now have the correct visibility on Windows
• MFCS devices return the correct error code when disconnected
• [Python] Added missing return statement to fgt_set_valvePosition
• [LabVIEW] fgt_get_inletPressure VI can now be found in the palette
• [LabVIEW] Fixed paths to the DLL functions for some VIs
• [LabVIEW] Updated the HTML documentation

22.0.0 Release

Added

• Support for the new Flow Unit ranges M+ and L+.
• Support for the F-OEM instruments.
• New function fgt_get_sensorAirBubbleFlag to read a flag that
  indicates whether the sensor detects air in the line. Only supported by
  M+ and L+ sensors.
• New function fgt_set_digitalOutput to set the F-OEM outputs.
• New function fgt_get_inletPressure to read the supply pressure of
  a pressure controller if available.

Changed

• M-Switch set position timeout increased to 10 seconds to account for
  hardware delays.
• fgt_set_valvePosition returns a Processing error if the function
  times out without reaching the requested position.

Fixed

• Switch EZ no longer ignores commands that are sent in quick
  succession.
• Reloading instruments now works properly when previously initialized
  instrument are missing.
• Custom regulation accounts for pressure limit changes while running.

21.4.0 Release

Added

• Functions to add and remove simulated instruments

Fixed

• After replacing a Flow Unit on a Flow EZ, the type is updated on reinit
• Switchboard correctly returns an error on fgt_get_power if it is not connected
• Switchboard and Switch EZ commands sent in quick succession are less
  likely to be ignored by the instrument. A 60ms delay is still recommended.

21.3.0 Release

Added

• Support for ARM (32 and 64 bits) on Linux
• Option to suppress error message output on middleware

Changed
