Important: While the module performs the configuration alteration, it
does not monitor input device data change at any channel.
Verifying Channel
Configuration
Changes When executing a dynamic channel configuration change, there will
always be a delay from the time the ladder program makes the change
to the time the NI8u gives you a data word using that new configuration
information. Therefore, it is very important to verify that a dynamic
channel configuration change took effect in the module, particularly if
the channel being dynamically configured is used for control. The
following example explains how to verify that channel configuration
changes have taken effect.
Example - Execute a dynamic configuration change to channel 2 of the
universal module located in slot 3 of a 1746 chassis, and set an internal
“data valid” bit when the new configuration has taken effect. In this
example the input image of the channel is selected to contain the
channel status word.
