Issue Details

I would like to use my C Series Digital Module with an encoder in FlexLogger, so I can use it to measure angular velocity. However, when I go to configure it, the only option for Physical Measurement is Digital: 

Solution

In order to be configured with an encoder, FlexLogger needs access to a counter. FlexLogger cannot use the on board counter of a cDAQ chassis, and C Series Modules don't contain counters, therefore, most C Series Modules cannot be configured with an encoder as normal cDAQ counter channels.

There is one exception to this rule, the NI-9361 Counter Input Module, which contains 8 embedded counters. With this module you can configure your channels with an encoder. Below is an example using this set up to measure angular velocity:


This set up gives you the option to make several different types of Physical Measurement as seen below:
