4-12 Module Data, Status, and Channel Configuration for the Output Modules
Ramping only takes place, if configured, when the output is being commanded
to go to a fault state. Ramping is not done in 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.
See Ramping Types on page 4-11 and 1769-OF4CI Output
Range/Types and Output Data Formats on page 4-11 for minimum
values.
or
 the number of counts entered for a channel’s ramp rate may be equal to
0 if ramping is not enabled for the channel.
