Ramping
Output ramping is used to limit the rate of change of an output
channel. You enter the rate as a percentage (between 0 and 200%) of
full scale per second, where 0 disables the ramping feature, and full
scale is the difference between the low and high scaling points. 4.3
shows the effect of ramping on the output signal.

Alarm Enable
Clamping and ramping are only active when the alarm enable bit
(decimal bit 17, octal bit 15) has been set to 1.
Reset State
This field determines the action taken by the channel if the I/O reset
backplane pin is asserted.
