Input Word Bit Definitions

Error Conditions (Bits 15 through 13)

There are eight possible error codes to describe any given state of the

1746-NI16 module. The following table shows the different error

codes and their associated bit settings. For more information on the

error codes, see “Error Codes” on page 6-5.

Filter Frequency (Bits 12 through 10)

The channel filter frequency bits reflects the filter frequency selected

in the configuration word. Filter frequencies are active for all current

and voltage input types. The filter frequency bits are cleared while the

channel is disabled.

NOTE

If the channel whose status you are checking is

disabled (bit O:e.x/15 = 0), all bit fields are cleared.

The status word for any disabled channel is always

0000 0000 0000 0000 regardless of any previous

setting that may have been made to the configuration

word in Class 3.
