Module Data, Status, and Channel Configuration Chapter 3
If configured, ramping takes place only when the output is
commanded to go to a fault state. Ramping does not occur during
normal run operation.
The ramp rate values are entered in the Configuration Data file and
are accepted as valid only if:
•
the number of counts entered for a channel’s ramp rate is
greater than or equal to a minimum of 1% of the total number of
full scale counts for the channel’s selected data format.
•
the number of counts entered for a channel’s ramp rate is equal
to zero and ramping is not enabled for that channel.
Output Type/Range Selection
This selection lets you configure each output channel individually and
provides the means of designating whether the output is a voltage or
current source. The output range for each output channel is also
configured by this selection.
