The bits are defined as follows:
• Sx = General status bits for channels 0…3. This bit is set when an error (over- or
under-range) exists for that channel, or there is a general module hardware error.
• Ox = Over-range flag bits for channels 0…3. These bits are set when the input signal is
above the user-specified range. The module continues to convert data to the maximum
full range value during an over-range condition. The bits reset when the over-range
condition clears.
• Ux = Under-range flag bits for input channels 0…3. These bits are set when the input
signal is below the user-specified range. The module continues to convert data to the
maximum full range value during an under-range condition. The bits reset when the
under-range condition clears.
• SGNx = The sign bit for channels 0…3.
Configuration Data File
The configuration of the format for analog inputs is made at going to run (GTR). Changes made
to the configuration file while in run mode have no effect.
The configuration table is shown below.
