FlexLogger Crashes While Opening Projects That Have at Least One Plugin Configured

FlexLogger may crash while opening a project that meets the following conditions:
  • The project was saved in FlexLogger 2020 R1 or earlier
  • The project has at least one plugin which consumes data from a FlexLogger channel
  • The project is being opened in FlexLogger 2020 R2, 2020 R3, 2020 R4, or 2021 R1

Workaround:

  1. Open the project on a computer using the same version of FlexLogger with which you created and saved the project.
  2. Delete all plugins from the project and save a copy of the project.
  3. Move the copied project to a computer with the desired version of FlexLogger installed and open it.
  4. Add the plugins back to the project and re-apply their configuration.

Formula Output Incorrect When Operating on Both Digital and Analog Channels

FlexLogger may map channels incorrectly and produce the wrong output from any formula that includes both digital (any channel that has a boolean value) and analog channels (any channel that has a numeric value). If the name of a digital channel comes alphabetically before the name of any analog channels in the formula, then the channels will get mapped to the wrong position in the formula. For example, the formula "b_digital ? a_analog : c_analog" would be mapped incorrectly because the name "b_digital" comes before "c_analog" alphabetically.

Workaround:

Rename channels so that, alphabetically, all analog channels are before any digital channels. You can use the attached tool, FlexLogger2020FormulaDiagnosticUtility, to determine if any of your projects may be affected by this issue.

Adding DAQ Channels in a Non-sequential Order Corrupts Anything Referencing a Channel

When new DAQ channels are configured in non-sequential order within a device (PXI, cDAQ, FieldDAQ, USB, etc.), any existing or future calculated channels, plugins, logging triggers, and events reference the wrong channel. This means that calculated channels and plugins will be operating on the wrong data and events and triggers may not fire when expected. To obtain more information, click the link below.

Workaround:

Save and re-open your project after you have finished all new channel configurations and before you validate the project.

Reported Version:
