Channel Configuration, Data, and Status 5-17
The channel status word can be analyzed bit by bit. In addition to
providing information about an enabled or disabled channel, each
bit’s status (0 or 1) tells you how the input data from the voltage or
current analog sensor connected to a specific channel is translated for
your application. The bit status also informs you of any error
condition and can tell you what type of error occurred.
A bit-by-bit examination of the status word for Class 1 and Class 3 is
provided in the respective charts on the following pages.
