Dynamic
Programming
The following example explains how to change data in the channel
configuration word when the channel is currently enabled.
Example - Execute a dynamic configuration change to channel 2 of the
universal module located in slot 3 of a 1746 chassis. Change from
monitoring a bipolar 10 V signal to monitoring the CJC sensors
mounted on the terminal block. This gives a good indication of what
the temperature is inside the control cabinet. Finally, set channel 2 back
to the bipolar 10 V range.
