Invalid Clamp Value Selected

These error codes occur when the value entered is not within the
full-range limits of the indicated channel, as determined by the
channel’s output range/type and format setting, or if the low clamp
value is greater than the high clamp value.

Invalid Ramp Rate Selected

(1)

These codes occur when the value entered is less than 1% or more
than 100% of the total full-range counts for the indicated channel, as
determined by the channel’s output range/type and format setting,
unless output ramping is disabled for the indicated channel. In that
case, the ramp rate may be set to zero without causing a configuration
error.

Invalid Real Time Sample Value

This error code occurs when the data entered for the Real Time
Sample value is less than 0 or is greater than 5000 (decimal).

See

Real Time Sampling on page 46

for details.

Module Inhibit Function

CompactLogix controllers support the module inhibit function. See
your controller manual for details.

Whenever the module is inhibited, it continues to provide information
about changes at its inputs to the 1769 Compact Bus Master (for
example, a CompactLogix controller).

(1) Some controllers do not support alternate output states. Refer to your controller user manual to determine

whether alternate output statues and these associated functions are supported.
